During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:26 Lois: Hello and welcome to the Oracle University Podcast! I'm Lois Houston, Director of Communications and Adoption with Customer Success Services, and with me is Nikita Abraham, Team Lead: Editorial Services with Oracle University. Nikita: Hi everyone! In our last episode, we explored the security and migration strengths of Oracle Database@AWS. Today, we're joined once again by Senior Principal Database Instructor Rashmi Panda to look at how the platform keeps your database available and resilient behind the scenes. 01:00 Lois: It's really great to have you with us, Rashmi. As many of you may know, keeping critical business applications running smoothly is essential for success. And that's why it's so important to have deployments that are highly resilient to unexpected failures, whether those failures are hardware-, software-, or network-related. With that in mind, Rashmi, could you tell us about the Oracle technologies that help keep the database available when those kinds of issues occur? Rashmi: Databases deployed in Oracle Database@AWS are built on Oracle's Foundational High Availability Architecture. Oracle Real Application Cluster or Oracle RAC is an Active-Active architecture where multiple database instances are concurrently running on separate servers, all accessing the same physical database stored in a shared storage to simultaneously process various application workloads. Even though each instance runs on a separate server, they collectively appear as a single unified database to the application. As the workload grows and demands additional computing capacity, then new nodes can be added to the cluster to spin up new database instances to support additional computing requirements. This enables you to scale out your database deployments without having to bring down your application and eliminates the need to replace existing servers with high-capacity ones, offering a more cost-effective solution. 02:19 Nikita: That's really interesting, Rashmi. It sounds like Oracle RAC offers both scalability and resilience for mission-critical applications. But of course, even the most robust systems require regular maintenance to keep them running at their best. So, how does planned maintenance affect performance? Rashmi: Maintenance on databases can take a toll on your application uptime. Database maintenance activities typically include applying of database patches or performing updates. Along with the database updates, there may also be updates to the host operating system. These operations often demand significant downtime for the database, which consequently leads to slightly higher application downtime. Oracle Real Application Cluster provides rolling patching and rolling upgrades feature, enabling patching and upgrades in a rolling fashion without bringing down the...

In this episode, hosts Lois Houston and Nikita Abraham are joined by special guests Samvit Mishra and Rashmi Panda for an in-depth discussion on security and migration with Oracle Database@AWS. Samvit shares essential security best practices, compliance guidance, and data protection mechanisms to safeguard Oracle databases in AWS, while Rashmi walks through Oracle's powerful Zero-Downtime Migration (ZDM) tool, explaining how to achieve seamless, reliable migrations with minimal disruption.

During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:26 Nikita: Welcome to the Oracle University Podcast! I'm Nikita Abraham, Team Lead: Editorial Services with Oracle University, and with me is Lois Houston, Director of Communications and Adoption with Customer Success Services. Lois: Hello again! We're continuing our discussion on Oracle Database@AWS and in today's episode, we're going to talk about the aspects of security and migration with two special guests: Samvit Mishra and Rashmi Panda. Samvit is a Senior Manager and Rashmi is a Senior Principal Database Instructor. 00:59 Nikita: Hi Samvit and Rashmi! Samvit, let's begin with you. What are the recommended security best practices and data protection mechanisms for Oracle Database@AWS? Samvit: Instead of everyone using the root account, which has full access, we create individual users with AWS, IAM, Identity Center, or IAM service. And in addition, you must use multi-factor authentication. So basically, as an example, you need a password and a temporary code from virtual MFA app to log in to the console. Always use SSL or TLS to communicate with AWS services. This ensures data in transit is encrypted. Without TLS, the sensitive information like credentials or database queries can be intercepted. AWS CloudTrail records every action taken in your AWS account-- who did what, when, and from where. This helps with audit, troubleshooting, and detecting suspicious activity. So you must set up API and user activity logging with AWS CloudTrail. Use AWS encryption solutions along with all default security controls within AWS services. To store and manage keys by using transparent data encryption, which is enabled by default, Oracle Database@AWS uses OCI vaults. Currently, Oracle Database@AWS doesn't support the AWS Key Management Service. You should also use advanced managed security services such as Amazon Macie, which assists in discovering and securing sensitive data that is stored in Amazon S3. 03:08 Lois: And how does Oracle Database@AWS deliver strong security and compliance? Samvit: Oracle Database@AWS enforces transparent data encryption for all data at REST, ensuring stored information is always protected. Data in transit is secured using SSL and Native Network Encryption, providing end-to-end confidentiality. Oracle Database@AWS also uses OCI Vault for centralized and secure key management. This allows organizations to manage encryption keys with fine-grained control, rotation policies, and audit capabilities to ensure compliance with regulatory standards. At the database level, Oracle Database@AWS supports unified auditing and fine-grained auditing to track user activity and sensitive operations. At the resource level, AWS CloudTrail and OCI audit service provide...

If you've ever wondered how Oracle Database really works inside AWS, this episode will finally turn the lights on. Join Senior Principal OCI Instructor Susan Jang as she explains the two database services available (Exadata Database Service and Autonomous Database), how Oracle and AWS share responsibilities behind the scenes, and which essential tasks still land on your plate after deployment. You'll discover how automation, scaling, and security actually work, and which model best fits your needs, whether you want hands-off simplicity or deeper control.

Let's get started! 00:26 Lois: Hello and welcome to the Oracle University Podcast! I'm Lois Houston, Director of Communications and Adoption with Customer Success Services, and with me is Nikita Abraham, Team Lead: Editorial Services with Oracle University. Nikita: Hi everyone! In our last episode, we began the discussion on Oracle Database@AWS. Today, we're diving deeper into the database services that are available in this environment. Susan Jang, our Senior Principal OCI Instructor, joins us once again. 00:56 Lois: Hi Susan! Thanks for being here today. In our last conversation, we compared Oracle Autonomous Database and Exadata Database Service. Can you elaborate on the fundamental differences between these two services? Susan: Now, the primary difference is between the service is really the management model. The Autonomous is fully-managed by Oracle, while the Exadata provides flexibility for you to have the ability to customize your database environment while still having the infrastructure be managed by Oracle. 01:30 Nikita: When it comes to running Oracle Database@AWS, how do Oracle and AWS each chip in? Could you break down what each provider is responsible for in this setup? Susan: Oracle Database@AWS is a collaboration between Oracle, as well as AWS. It allows the customer to deploy and run Oracle Database services, including the Oracle Autonomous Database and the Oracle Exadata Database Service directly in AWS data centers. Oracle provides the ability of having the Oracle Exadata Database Service on a dedicated infrastructure. This service delivers full capabilities of Oracle Exadata Database on the Oracle Exadata hardware. It offers high performance and high security for demanding workloads. It has cloud automation, resource scaling, and performance optimization to simplify the management of the service. Oracle Autonomous Database on the dedicated Exadata infrastructure provides a fully Autonomous Database on this dedicated infrastructure within AWS. It automates the database management tasks, including patching, backups, as well as tuning, and have built-in AI capabilities for developing AI-powered applications and interacting with data using natural language. The Oracle Database@AWS integrates those core database services with various AWS services for a comprehensive unified experience. AWS provides the ability of having a cloud-based object storage, and that would be the Amazon S3. You also have the ability to have other services, such as the Amazon CloudWatch. It monitors the database metrics, as well as performance. You also have Amazon Bedrock. It provides a development environment for a generative AI...

In this episode, hosts Lois Houston and Nikita Abraham take you inside how Oracle brings its industry-leading database technology directly to AWS customers. Senior Principal OCI Instructor Susan Jang unpacks what the OCI child site is, how Exadata hardware is deployed inside AWS data centers, and how the ODB network enables secure, low-latency connections so your mission-critical workloads can run seamlessly alongside AWS services. Susan also walks through the differences between Exadata Database Service and Autonomous Database, helping teams choose the right level of control and automation for their cloud databases.

During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:26 Nikita: Welcome to the Oracle University Podcast! I'm Nikita Abraham, Team Lead: Editorial Services with Oracle University, and with me is Lois Houston, Director of Communications and Adoption with Customer Success Services. Lois: Hi there! Last week, we talked about multicloud and the partnerships Oracle has with Microsoft Azure, Google Cloud, and Amazon Web Services. If you missed that episode, do listen to it as it sets the foundation for today's discussion, which is going to be about Oracle Database@AWS. 00:59 Nikita: That's right. And we're joined by Susan Jang, a Senior Principal OCI Instructor. Susan, thanks for being here. To start us off, what is Oracle Database@AWS? Susan: Oracle Database@AWS is a service that allows Oracle Exadata infrastructure that is managed by Oracle Cloud Infrastructure, or OCI, to run directly inside an AWS data center. 01:25 Lois: Susan, can you go through the key architecture components and networking relationships involved in this? Susan: The AWS Cloud is the Amazon Web Service. It's a cloud computing platform. The AWS region is a distinct, isolated geographic location with multiple physically separated data center, also known as availability zone. The availability zone is really a physically isolated data center with its own independent power, cooling, and network connectivity. When we speak of the AWS data center, it's a highly secured, specialized physical facility that houses the computing storage, the compute servers, the storage server, and the networking equipment. The VPC, the Virtual Private Cloud, is a logical, isolated virtual network. The AWS ODB network is a private user-created network that connects the virtual private cloud network of Amazon resources with an Oracle Cloud Infrastructure Exadata system. This is all within an AWS data center. The AWS-ADB peering is really an established private network connection that's between the Oracle VPC, the Virtual Private Cloud, and the Oracle Database@AWS network. And that would be the ODB. Within the AWS data center, you have something that you see called the child site. Now, an OCI child site is really a physical data center that is managed by Oracle within the AWS data center. It's a seamless extension of the Oracle Cloud Infrastructure. The site is hosting the Exadata infrastructure that's running the Oracle databases. The Oracle Database@AWS service brings the power as well as the performance of an Oracle Exadata infrastructure that is managed by Oracle Cloud Infrastructure to run directly in an AWS data center. 03:57 Nikita: So...

Multicloud is changing the way modern teams run their workloads: with real choice and real control. In this episode, hosts Lois Houston and Nikita Abraham welcome Senior Principal OCI Instructor Sergio Castro, who explains how Oracle has partnered with Microsoft Azure, Google Cloud, and AWS to bring Oracle Database directly inside their data centers, unlocking sub-millisecond latency and new levels of flexibility. They discuss how organizations can seamlessly migrate from on-premises or between clouds with minimal disruption, take advantage of best-in-class cloud services, and enhance business continuity.

Let's get started! 00:26 Lois: Hello and welcome to the Oracle University Podcast! I'm Lois Houston, Director of Communications and Adoption with Customer Success Services, and with me is Nikita Abraham, Team Lead: Editorial Services. Nikita: Hi everyone! We're kicking off a new season of the podcast today, this time on Oracle Database@AWS. But before we fully dive into that, we've got Sergio Castro with us to introduce multicloud and talk about some of its use cases. Sergio, who you may have heard on the podcast before, is a Senior Principal OCI Instructor with Oracle University. 01:02 Lois: Hi Sergio! Thanks for joining us today. We've spoken a lot about multicloud before, but we couldn't possibly discuss Oracle Database@AWS without another quick intro to multicloud. So, for anyone who doesn't already know, what is multicloud? And could you also talk about what Oracle is doing in this space? Sergio: It is the use of several Cloud providers to deliver an IT service. Basically, a multi-cloud strategy allows organizations to distribute their workloads across multiple Cloud platforms and providers. This will help aiding the flexibility when picking the right tool for each job. Basically, by selecting the best Cloud Service, IT architects can take advantage of each provider's strengths, including custom hardware, software, and service capabilities. And Oracle is a pioneer in multi-cloud. We have partnerships with Azure, Google Cloud, AWS, and we've been doing multi-cloud since 2019, including Oracle Interconnect for Azure and Oracle Interconnect for Google Cloud. Our multi-cloud products is the Oracle Database Service at Azure, at Google Cloud, and at AWS. Here we have our database inside the data centers of these Cloud Service providers. And multi-cloud can be complemented by resources that you have on-premises, providing you with a hybrid Cloud model. And our public Cloud offerings are not limited to the commercial realm. Multi-cloud is beginning to be available also in the government realm. You can now find Oracle Interconnect for Azure in the US government realm. We also have government realm offerings in the UK and in the European Union. And of course, dedicated Cloud. If you're going to be involving on-premises, you can also have all the Oracle Cloud Infrastructure resources behind your firewall, behind your routers with dedicated Cloud. So the offers from Oracle Cloud Infrastructure are really exceptional. It offers you great flexibility and choice. And the choice is yours. You select the platform for your Oracle Cloud solutions. 03:39 Nikita: You've already...

During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:26 Lois: Welcome to the Oracle University Podcast. I'm your host, Lois Houston, and I'm joined today by Jeffrey Malcolm, Operating Adviser working in the private equity space, to talk about how Oracle AI certifications have impacted his professional and personal life. Hi Jeffrey, thank you so much for taking the time to chat with us today. Our conversation actually stems from a fascinating discussion we had at AI World, Oracle's annual user conference. There you shared your journey to becoming Oracle AI certified... How that process not only shifted your perspective on emerging technologies, but also influenced the way you work, interact with colleagues and clients, and even how you encourage continued learning in your own family. I'm really excited to dive deeper into your story and explore the value and real world benefits of certification in today's AI-driven landscape. 01:20 Jeffrey: Uh Lois, first of all, thank you for having me. Um, it was fantastic running into your teammates at AI World. It was amazing. You know, for for me, you know, as we go through this AI journey with my portfolio companies, I'm constantly looking at what are the new things out there? How can I get myself enabled? So, excited that we're having this conversation today. 01:42 Lois: That's great. So, let's start at the beginning. Before your certifications, what was your initial reaction when you heard about Oracle's OCI and AI certification programs? Were you immediately interested or was there hesitation? Jeffrey: I was skeptical. You know, I was skeptical about OCI capabilities as you guys didn't have much market penetration at the time. You know, in my technology career, I built several enterprise applications on AWS, Azure, and GCP. However, OCI Cloud was new and my wife Kay Malcolm, who you know, kept raving at home over and over about OCI, that the cloud was faster, it was more secure and cost friendly. All of which this thing that I'm hearing are appealing to me as a CIO because that's something that I need to control at my companies that I'm working with. Lois: Right. Jeffrey: So because even though I was skeptical I was like if all of these things are appealing to her, I'm going to go ahead, I'm going to take the certification, I'm going to confirm all of these allegations that she's making to just make sure that, you know, it's actually true. And I was pleasantly surprised once I pulled the covers back. 02:59 Lois: So, you mentioned that your wife actually encouraged you to sign up for the free OCI Foundations training. Can you tell me a little bit more about that experience and how it influenced your decision to continue learning? Jeffrey: When she took the OCI test, at first she passed with a 95% score. So, you know, that encouraged me to just, you know, to take it as as as informative as I can. And to be honest, I wanted to beat her score because, you know, we're competitive. Um, upon passing and seeing...

Security, compliance, and resilience are the cornerstones of trust. In this episode, Lois Houston and Nikita Abraham continue their conversation with David Mills and Tijo Thomas, exploring how Oracle Cloud Infrastructure empowers organizations to protect data, stay compliant, and scale with confidence. Real-world examples from Zoom, KDDI, 8x8, and Uber highlight these capabilities.

During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:26 Lois: Hello and welcome to the Oracle University Podcast! I'm Lois Houston, Director of Communications and Adoption with Customer Success Services, and with me is Nikita Abraham, Team Lead: Editorial Services with Oracle University. Nikita: Hi everyone! In our last episode, we started the conversation around the real business value of Oracle Cloud Infrastructure and how it helps organizations create impact at scale. Lois: Today, we're taking a closer look at what keeps the value strong — things like security, compliance, and the technology that helps businesses stay resilient. To walk us through it, we have our experts from Oracle University, David Mills, Senior Principal PaaS Instructor, and Tijo Thomas, Principal OCI Instructor. 01:12 Nikita: Hi David and Tijo! It's great to have you both here! Tijo, let's start with you. How does Oracle Cloud Infrastructure help organizations stay secure? Tijo: OCI uses a security first approach to protect customer workloads. This is done with implementing a Zero Trust Model. A Zero Trust security model use frequent user authentication and authorization to protect assets while continuously monitoring for potential breaches. This would assume that no users, no devices, no applications are universally trusted. Continuous verification is always required. Access is granted only based on the context of request, the level of trust, and the sensitivity of that asset. There are three strategic pillars that Oracle security first approach is built on. The first one is being automated. With automation, the business doesn't have to rely on any manual work to stay secure. Threat detection, patching, and compliance checks, all these happen automatically. And that reduces human errors and also saving time. Security in OCI is always turned on. Encryption is automatic. Identity checks are continuous. Security is not an afterthought in OCI. It is incorporated into every single layer. Now, while we talk about Oracle's security first approach, remember security is a shared responsibility, and what that means while Oracle handles the data center, the hardware, the infrastructure, software, consumers are responsible for securing their apps, configurations and the data. 03:06 Lois: Tijo, let's discuss this with an example. Imagine an online store called MuShop. They're a fast-growing business selling cat products. Can you walk us through how a business like this can enhance its end-to-end security and compliance with OCI? Tijo: First of all, focusing on securing web servers. These servers host the web portal where customers would browse, they log in, and place their orders. So these web servers are a prime target for attackers. To protect these entry points, MuShop deployed a service called OCI Web Application Firewall. On top of that, the MuShop business have also used OCI security list...

Understanding cloud costs can be challenging, but it's essential for maximizing value. In this episode, hosts Lois Houston and Nikita Abraham speak with Oracle Cloud experts David Mills and Tijo Thomas about how Oracle Cloud Infrastructure offers predictable pricing, robust security, and high performance. They also introduce FinOps, a practical approach to tracking and optimizing cloud spending.

During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:27 Nikita: Welcome back to another episode of the Oracle University Podcast! I'm Nikita Abraham, Team Lead of Editorial Services with Oracle University, and I'm joined by Lois Houston, Director of Communications and Adoption with Customer Success Services. Lois: Hi everyone! Last week, we talked about how Oracle Cloud Infrastructure brings together developer tools, automation, and AI on a single platform. In today's episode, we're highlighting the real-world impact OCI can have on business outcomes. 00:58 Nikita: And to tell us about this, we have our experts David Mills and Tijo Thomas back with us. David is a Senior Principal PaaS Instructor and Tijo is a Principal OCI Instructor, and they're both from Oracle University. David, let's start with you. What makes Oracle Cloud Infrastructure the trusted choice for organizations across industries like banking, healthcare, retail, and government? David: It all comes down to one thing. OCI was built for real businesses, not side projects, not hobby apps, not test servers, but mission-critical systems at scale. Most clouds brag about their speed, but OCI is consistently fast, even under pressure. And that's because Oracle built OCI on a non-blocking network and bare metal infrastructure, with dedicated resources and no noisy neighbors. So, whether you're running one application or 1,000, you get predictable, low latency, performance every time as OCI doesn't force you into any specific mold. You want full control? Spin up a virtual machine and configure everything. You need to move fast? Use a managed service like Autonomous Database or Kubernetes. Prefer to build your own containers, functions, APIs, or develop with low code or even no code tools? OCI supports all of it. And it plays nicely with your existing stack—on-prem or in another cloud. OCI adapts to how you already work instead of making you start over. 02:39 Lois: And when it comes to pricing, how does OCI help customers manage costs more effectively? David: OCI is priced for real business use, not just the flashy low entry number. You only pay for what you use. No overprovisioning, no lock in. Virtual machines can scale up and down automatically. Object storage automatically shifts to a lower cost tier based on frequency of access. Autonomous services don't need babysitting or patching. And unlike some providers, OCI doesn't charge you to get your own data back. It's enterprise grade cloud without enterprise grade sticker shock. 03:26 Lois: Security and flexibility are top priorities for many organizations. How does OCI address those challenges? David: OCI treats security as a starting point, not an upsell. From the moment you create an account, every tenant is isolated. All data is encrypted. Admin activity is logged and security tools like Cloud Guard are ready to go. And if you need to prove...

Every system depends on reliable infrastructure behind the scenes. Oracle Cloud Infrastructure (OCI) delivers that reliability with speed, flexibility, and built-in security. Join Lois Houston and Nikita Abraham as they speak with Oracle Cloud experts David Mills and Tijo Thomas about what makes OCI different and how it drives real results for businesses of every size.

During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:26 Lois: Hello and welcome to the Oracle University Podcast! I'm Lois Houston, Director of Communications and Adoption with Customer Success Services, and with me is Nikita Abraham, Team Lead: Editorial Services with Oracle University. Nikita: Hi everyone, and welcome to a brand-new season of the podcast! We're really excited about this one because we'll be diving into how Oracle Cloud Infrastructure is transforming the way businesses innovate, stay secure, and drive results. 00:55 Lois: And to help us with this, we've got two experts who know this space inside out—David Mills, Senior Principal PaaS Instructor, and Tijo Thomas, Principal OCI Instructor, both from Oracle University. Hi David! For those who might not be familiar, could you explain what Oracle Cloud Infrastructure is? David: OCI, as we call it, is Oracle's enterprise grade cloud platform, built from the ground up to run the systems that matter most to business. It provides the infrastructure and platform services businesses need to build, run, and scale applications securely, globally, and cost effectively. To provide more context, all of Oracle's SaaS applications such as NetSuite, Customer Experience, Human Capital Management, Supply Chain Management, as well as Enterprise Resource and Enterprise Performance Management, they all run on OCI. But OCI isn't just for Oracle's own apps. It's a full featured cloud platform used by thousands of customers to run their own applications, data, and services. OCI includes platform services such as databases, integration, analytics, and many others, and of course, the infrastructure services, such as compute, networking, and storage, which comprise the core of OCI. Bottom line, if something is running on Oracle Cloud, OCI is behind it. OCI includes over 100 services across numerous categories like compute, storage, networking, database, containers, AI, developer tools, integration, security, observability, and much more. So, whether you're lifting and shifting legacy workloads or building new apps in the cloud, OCI has the building blocks. 03:02 Lois: David, who was OCI designed for? David: OCI was built from scratch to address the limitations of first-generation clouds. No patchwork of legacy acquisitions, just a clean, modern, high-performance foundation designed for real enterprise workloads. OCI was designed for businesses that can't compromise financial services, health care, retail, governments, customers with strict regulations, global scale, and mission-critical systems. These are the companies choosing OCI not just because it works, but because it works under pressure. 03:42 Nikita: What else makes OCI different from other cloud platforms? David: Oracle's network and storage architecture delivers low latency results consistently. Then there's pricing—simple, predictable, and often much lower than our competitors. OCI was...

Today's episode is the last one in this series and is a throwback to a conversation on APEX with Chaitanya Koratamaddi, Director of Product Management for Oracle APEX. 00:57 Lois: We began by asking Chaitanya what Oracle APEX is and why it's so widely used. So, let's jump right in! Chaitanya: Oracle APEX is the world's most popular enterprise low code application platform. APEX enables you to build secure and scalable enterprise-scale applications with world class features that can be deployed anywhere, cloud or on-premises. And with APEX, you can build applications 20 times faster with 100 times less code. APEX delivers the most productive way to develop and deploy mobile and web applications everywhere. 01:40 Lois: That's impressive. So, what's the adoption rate like for Oracle APEX? Chaitanya: As of today, there are 19 million plus APEX applications created globally. 5,000 plus APEX applications are created on a daily basis and there are 800,000 plus APEX developers worldwide. 60,000 plus customers in 150 countries across various industry verticals. And 75% of Fortune 500 companies use Oracle APEX. 02:19 Nikita: Wow, the numbers really speak for themselves, right? But Chaitanya, why are organizations adopting Oracle APEX at this scale? Or to put it differently, what's the core business challenge that Oracle APEX is addressing? Chaitanya: From databases to all data, you know that the world is more connected and automated than ever. To drive new business value, organizations need to explore and exploit new sources of data that are generated from this connected world. That can be sounds, feeds, sensors, videos, images, and more. Businesses need to be able to work with all types of data and also make sure that it is available to be used together. Typically, businesses need to work on all data at a massive scale. For example, supply chains are no longer dependent just on inventory, demand, and order management signals. A manufacturer should be able to understand data describing global weather patterns and how it impacts their supply chains. Businesses need to pull in data from as many social sources as possible to understand how customer sentiment impacts product sales and corporate brands. Our customers need a data platform that ensures all this data works together seamlessly and easily. 04:00 Lois: So, you're saying Oracle APEX is the platform that helps businesses manage and...

I'm Lois Houston, Director of Communications and Adoption with Customer Success Services, and with me is Nikita Abraham, Team Lead: Editorial Services with Oracle University. Nikita: Hi everyone! You're listening to our Best of 2025 series, where over the next few weeks, we're revisiting four of our most popular episodes of the year. Lois: Today is #2 of 4, and we're throwing it back to an episode with Senior Manager of CSS OU Cloud Delivery Samvit Mishra. This episode was all about shining a light on multicloud, a game-changing strategy involving the use of multiple cloud service providers. 01:07 Nikita: That's right, Lois. Oracle has been an early adopter of multicloud and a pioneer in multicloud services. So, we began that conversation by asking Samvit to explain what multicloud is and why someone would need more than one cloud provider. Samvit: Multicloud is a very simple, basic concept. It is the coordinated use of cloud services from more than one cloud service provider. 01:30 Nikita: But why would someone want to use more than one cloud service provider? Samvit: There are many reasons why a customer might want to leverage two or more cloud service providers. First, it addresses the very real concern of mitigating or avoiding vendor lock-in. By using multiple providers, companies can avoid being tied down to one vendor and maintain their flexibility. 01:53 Lois: That's like not putting all your eggs in one basket, so to speak. Samvit: Exactly. Another reason is that customers want the best of breed. What that means is basically leveraging or utilizing the best product from one cloud service provider and pairing it against the best product from another cloud service provider. Getting a solution out of the combined products…out of the coordinated use of those services. 02:22 Nikita: So, it sounds like multicloud is becoming the new normal. And as we were saying before, Oracle was a pioneer in this space. But why did we embrace multicloud so wholeheartedly? Samvit: We recognized that our customers were already moving in this direction. Independent studies from Flexera found that 89% of the subjects of the study used multicloud. And we conducted our own study and came to similar numbers. Over 90% of our customers use two or more cloud service providers. HashiCorp, the big infrastructure as code company, came to similar numbers as well, 94%. They basically asked companies if multicloud helped them advance their business goals. And 94% said yes. And all this is very recent data. 03:13 Lois: Can you give us the backstory of Oracle's entry into the multicloud...

During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:25 Lois: Hello and welcome to the Oracle University Podcast! I'm Lois Houston, Director of Innovation Programs with Oracle University, and with me is Nikita Abraham, Team Lead: Editorial Services. Nikita: Hey everyone! Last week, we discussed how you can keep your data safe with authentication and authorization. Today, we'll talk about various security risks that could threaten your systems. 00:48 Lois: And to help us understand this better, we have Orlando Gentil, Principal OCI Instructor, back with us. Orlando, welcome back! Let's start with the big picture—why is security such a crucial part of our digital world today? Orlando: Whether you are dealing with files stored on a server or data flying across the internet, one thing is always true—security matters. In today's digital world, it's critical to ensure that data stays private, accurate, and accessible only to the right people. 01:20 Nikita: And how do we keep data private, secure, and unaltered? Is there a security framework that we can use to make sense of different security practices? Orlando: The CIA triad defines three core goals of information security. CIA stands for confidentiality. It's about keeping data private. Only authorized users should be able to access sensitive information. This is where encryption plays a huge role. Integrity means ensuring that the data hasn't been altered, whether accidentally or maliciously. That's where hashing helps. You can compare a stored hash of data to a new hash to make sure nothing's changed. Availability ensures that data is accessible when it's needed. This includes protections like system redundancy, backups, and anti-DDoS mechanisms. Encryption and hashing directly support confidentiality and integrity. And they indirectly support availability by helping keep systems secure and resilient. 02:31 Lois: Let's rewind a bit. You spoke about something called hashing. What does that mean? Orlando: Hashing is a one-way transformation. You feed in data and it produces a unique fixed length string called a hash. The important part is the same input always gives the same output, but you cannot go backward and recover the original data from the hash. It's commonly used for verifying integrity. For example, to check if a file has changed or a message was altered in transit. Hashing is also used in password storage. Systems don't store actual passwords, just their hashes. When you log in, the system hashes what you type it and compare the stored hash. If they match, you're in. But your actual password was never stored or revealed. So hashing isn't about hiding data, it's about providing it hasn't changed. So, while hashing is all about protecting integrity, encryption is the tool we use to ensure confidentiality. 03:42 Nikita: Right, the C in CIA. And how does it do that? Orlando: Encryption takes readable data, also known as plaintext, and turns it into something unreadable called ciphertext...

How do all your devices connect and stay safe in the cloud? In this episode, Lois Houston and Nikita Abraham talk with OCI instructors Sergio Castro and Orlando Gentil about the basics of how networks work and the simple steps that help protect them. You'll learn how information gets from one place to another, why tools like switches, routers, and firewalls are important, and what goes into keeping access secure. The discussion also covers how organizations decide who can enter their systems and how they keep track of activity.

During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:25 Lois: Hello and welcome to the Oracle University Podcast! I'm Lois Houston, Director of Innovation Programs with Oracle University, and with me is Nikita Abraham, Team Lead: Editorial Services. Nikita: Hi everyone! In the last episode, we spoke about local area networks and domain name systems. Today, we'll continue our conversation on the fundamentals of networking, covering a variety of important topics. 00:50 Lois: That's right, Niki. And before we close, we'll also touch on the basics of security. Joining us today are two OCI instructors from Oracle University: Sergio Castro and Orlando Gentil. So glad to have you both with us guys. Sergio, with so many users and devices connecting to the internet, how do we make sure everyone can get online? Can you break down what Network Address Translation, or NAT, does to help with this? Sergio: The world population is bigger than 4.3 billion people. That means that if we were to interconnect every single human into the internet, we will not have enough addresses. And not all of us are connected to the internet, but those of us who are, you know that we have more than one device at our disposal. We might have a computer, a laptop, mobile phones, you name it. And all of them need IP addresses. So that's why Network Address Translation exists because it translates your communication from a private IP to a public IP address. That's the main purpose: translate. 02:05 Nikita: Okay, so with NAT handling the IP translation, how do we ensure that the right data reaches the right device within a network? Or to put it differently, what directs external traffic to specific devices inside a network? Sergio: Port forwarding works in a reverse way to Network Address Translation. So, let's assume that this PC here, you want to turn it into a web server. So, people from the outside, customers from the outside of your local area network, will access your PC web server. Let's say that it's an online store. Now all of these devices are using the same public IP address. So how would the traffic be routed specifically to this PC and not to the camera or to the laptop, which is not a web server, or to your IP TV? So, this is where port forwarding comes into play. Basically, whenever it detects a request coming to port, it will route it and forward that request to your PC. It will allow anybody, any external device that wants to access this particular one, this particular web server, for the session to be established. So, it's a permission that you're allowing to this PC and only to this PC. The other devices will still be isolated from that list. That's what port forwarding is. 03:36 Lois: Sergio, let's talk about networking devices. What are some of the key ones, and...

In this episode, hosts Lois Houston and Nikita Abraham team up with Senior Principal OCI Instructor Sergio Castro to unpack the basics of cloud networking and the Domain Name System (DNS).

During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:25 Lois: Hello and welcome to the Oracle University Podcast! I'm Lois Houston, Director of Innovation Programs with Oracle University, and with me is Nikita Abraham, Team Lead: Editorial Services. Nikita: Hi everyone! For the last few weeks, we've been talking about different aspects of cloud data centers. Today, we're focusing on something that's absolutely key to how everything works in the cloud: networking and domain name systems. 00:52 Lois: And to guide us through it, we've got Sergio Castro, Senior Principal OCI Instructor at Oracle University. We'll start by trying to understand why networking is so crucial and how it connects everything behind the scenes. Sergio, could you explain what networking means in simple terms, especially for folks new to cloud tech? Sergio: Networking is the backbone of cloud computing. It is a fundamental service because it provides the infrastructure for connecting users, applications, and resources within a cloud environment. It basically enables data transfers. It facilitates remote access. And ensures that cloud services are accessible to users. This provided that these users have the correct credentials. 01:38 Nikita: Ok, can you walk us through how a typical network operates? Sergio: In networking, typically starts with the local area network. Basically, networking is a crucial component for any IT service because it's the foundation for the architecture framework of any of the services that we consume today. So, a network is two or more computers interconnected to each other. And not necessarily it needs to be a computer. It can be another device such as a printer or an IP TV or an IP phone or an IP camera. Many devices can be part of a local area network. And a local area network can be very small. Like I mentioned before, two or more computers, or it could grow into a very robust and complicated set of interconnected networks. And if that happens, then it can become very expensive as well. Cloud networking, it's the Achilles heel for many of the database administrators, programmers, quality assurance engineers, any IT other than a network administrator. Actually, when the network starts to grow, managing access and permissions and implementing robust security measures, this coupled with the critical importance of reliable, and secure performance, can create significant hurdles. 03:09 Nikita: What are the different types of networks we have? Sergio: A local area network is basically in one building. It covers… it can be maybe two buildings that are in close proximity in a small campus, but typically it's very small by definition, and they're all interconnected to each other via one router, typically. A metropolitan area network is a typical network that spans into a city or a metro area, hence the name metropolitan area network. So, one building can be on one edge of the city and the other building can be at the other edge...

In this episode, hosts Lois Houston and Nikita Abraham, along with Principal OCI Instructor Orlando Gentil, break down the differences between Infrastructure-as-a-Service, Platform-as-a-Service, and Software-as-a-Service.

During this series of informative podcasts, we’ll bring you foundational training on the most popular Oracle technologies. Let’s get started! 00:25 Nikita: Welcome to the Oracle University Podcast! I’m Nikita Abraham, Team Lead: Editorial Services with Oracle University, and with me is Lois Houston, Director of Innovation Programs. Lois: Hey there! Last week, we spoke about how hypervisors, virtual machines, and containers have transformed data centers. Today, we’re moving on to something just as important—the main cloud models that drive modern cloud computing. Nikita: Orlando Gentil, Principal OCI Instructor at Oracle University, joins us once again for part four of our discussion on cloud data centers. 01:01 Lois: Hi Orlando! Glad to have you with us today. Can you walk us through the different types of cloud models? Orlando: These are commonly categorized into three main service models: Infrastructure-as-a-Service, Platform-as-a-Service, and Software-as-a-Service. Let's use the idea of getting around town to understand cloud service models. IaaS is like renting a car. You don't own the car, but you control where it goes, how fast, and when to stop. In cloud terms, the provider gives you the infrastructure—virtual machines, storage, and networking—but you manage everything on top—the OS, middleware, runtime, and application. Thus, it's like using a shuttle service. You bring your bags—your code, pick your destination—your app requirements, but someone else drives and maintains the vehicle. You don't worry about the engine, fuel, or routing planning. That's the platform's job. Your focus stays on development and deployment, not on servers or patching. SaaS is like ordering a taxi. You say where you want to go and everything else is handled for you. It's the full-service experience. In the cloud, SaaS is software UXs over the web—Email, CRM, project management. No infrastructure, no updates, just productivity. 02:32 Nikita: Ok. How do the trade-offs between control and convenience differ across SaaS, PaaS, and IaaS? Orlando: With IaaS, much like renting a car, you gain high control. You are managing components like the operating system, runtime, your applications, and your data. In return, the provider expertly handles the underlying virtual machines, storage, and networking. This model gives you immense flexibility. Moving to PaaS, our shuttle service, you shift to a medium level of control but gain significantly higher convenience. Your primary focus remains on your application code and data. The provider now takes on the heavy lifting of managing the runtime environment, the operating system, the servers themselves, and even the scaling. Finally, SaaS, our taxi service, offers the highest convenience with the lowest control level. Here, your responsibility is essentially just using the application and managing your specific configurations or data within it. The cloud provider manages absolutely everything else—the entire infrastructure, the platform, and the application itself. 03:52 Nikita: One...

I’m Lois Houston, Director of Innovation Programs with Oracle University, and with me is Nikita Abraham, Team Lead: Editorial Services. Nikita: Hi everyone! For the last two weeks, we’ve been talking about different aspects of cloud data centers. In this episode, Orlando Gentil, Principal OCI Instructor at Oracle University, joins us once again to discuss how virtualization, through hypervisors, virtual machines, and containers, has transformed data centers. 00:58 Lois: That’s right, Niki. We’ll begin with a quick look at the history of virtualization and why it became so widely adopted. Orlando, what can you tell us about that? Orlando: To truly grasp the power of virtualization, it's helpful to understand its journey from its humble beginnings with mainframes to its pivotal role in today's cloud computing landscape. It might surprise you, but virtualization isn't a new concept. Its roots go back to the 1960s with mainframes. In those early days, the primary goal was to isolate workloads on a single powerful mainframe, allowing different applications to run without interfering with each other. As we moved into the 1990s, the challenge shifted to underutilized physical servers. Organizations often had numerous dedicated servers, each running a single application, leading to significant waste of computing resources. This led to the emergence of virtualization as we know it today, primarily from the 1990s to the 2000s. The core idea here was to run multiple isolated operating systems on a single physical server. This innovation dramatically improved the resource utilization and laid the technical foundation for cloud computing, enabling the scalable and flexible environments we rely on today. 02:26 Nikita: Interesting. So, from an economic standpoint, what pushed traditional data centers to change and opened the door to virtualization? Orlando: In the past, running applications often meant running them on dedicated physical servers. This led to a few significant challenges. First, more hardware purchases. Every new application, every new project often required its own dedicated server. This meant constantly buying new physical hardware, which quickly escalated capital expenditure. Secondly, and hand-in-hand with more servers came higher power and cooling costs. Each physical server consumed power and generated heat, necessitating significant investment in electricity and cooling infrastructure. The more servers, the higher these operational expenses became. And finally, a major problem was unused capacity. Despite investing heavily in these physical servers, it was common for them to run well below their full capacity. Applications typically didn't...

During this series of informative podcasts, we’ll bring you foundational training on the most popular Oracle technologies. Let’s get started! 00:25 Lois: Hello and welcome to the Oracle University Podcast! I’m Lois Houston, Director of Innovation Programs with Oracle University, and with me is Nikita Abraham, Team Lead: Editorial Services. Nikita: Hi everyone! Today, we’re covering the fundamentals you need to be successful in a cloud environment. If you’re new to cloud, coming from a SaaS environment, or planning to move from on-premises to the cloud, you won’t want to miss this. With us today is Orlando Gentil, Principal OCI Instructor at Oracle University. Hi Orlando! Thanks for joining us. 01:01 Lois: So Orlando, we know that Oracle has been a pioneer of cloud technologies and has been pivotal in shaping modern cloud data centers, which are different from traditional data centers. For our listeners who might be new to this, could you tell us what a traditional data center is? Orlando: A traditional data center is a physical facility that houses an organization's mission critical IT infrastructure, including servers, storage systems, and networking equipment, all managed on site. 01:32 Nikita: So why would anyone want to use a cloud data center? Orlando: The traditional model requires significant upfront investment in physical hardware, which you are then responsible for maintaining along with the underlying infrastructure like physical security, HVAC, backup power, and communication links. In contrast, cloud data centers offer a more agile approach. You essentially rent the infrastructure you need, paying only for what you use. In the traditional data center, scaling resources up and down can be a slow and complex process. On cloud data centers, scaling is automated and elastic, allowing resources to adjust dynamically based on demand. This shift allows business to move their focus from the constant upkeep of infrastructure to innovation and growth. The move represents a shift from maintenance to momentum, enabling optimized costs and efficient scaling. This fundamental shift is how IT infrastructure is managed and consumed, and precisely what we mean by moving to the cloud. 02:39 Lois: So, when we talk about moving to the cloud, what does it really mean for businesses today? Orlando: Moving to the cloud represents the strategic transition from managing your own on-premise hardware and software to leveraging internet-based computing services provided by a third-party. This involves migrating your applications, data, and IT operations to a cloud environment. This transition typically aims to reduce operational overhead, increase flexibility, and enhance scalability, allowing organizations to focus more on their core business functions. 03:17 Nikita: Orlando, what’s the “brain” behind all this technology? Orlando: A CPU or Central Processing Unit is the primary component that performs most of the processing inside the computer or...
