Tanzu Talk

JT Perry is back to talk about enterprise AI in healthcare. They also talk about the status of new business models like "doc in a box" and Amazon Health. See the full show notes in the video version of this episode.

Fresh from working on developer platforms at Uber, Serdar Badem tells us his experience working on improving developer productivity. He's working at Tanzu now and so he also discusses the work we're doing to help improve developer productivity.

The phrase "value stream" is used so often in software development that it's easy to forget exactly what it means. "Waste" is another word like that. In this episode, Coté talks with Steve Pereira about value stream mappings, what waste is, exactly, and why it's so difficult to do what seems like an obviously good idea, like value stream mapping. - Steve in LinkedIn. - Steve's book. - Flow community. - Awesome waste/countermeasure handout, including definitions of waste.

In this episode Coté talks with Laura Tacho, the CTO of DX on several topics, starting with tech debt. Laura shares her viewpoint on how the concept and use of 'tech debt' changes based on perspective, and the need for better quantification of these concepts for businesses. They also discuss developer productivity metrics and three types of meetings. Read all of Laura's great articles here.

You always hear that making a series of small changes is better than BIG BANG change. How does this really play out though? Doesn't that seem a little...naive when it comes to large organizations doing the BIG and MISSION CRITICAL work? In this episode, Coté talks with Betty Junod on this topic. She draws from many sources like her first hand experience as an executive and working with the DevOps and cloud native community. They also discuss making culture changes in organizations and how recent work to figure out how to determine "business value." Watch the video of this recording if you prefer that kind of thing.

Ben educates Coté on what Backstage is. Coté is always thinking that new tech does more than it actually does, and he eagerly de-scopes his inflated expectations with Ben's wiseness. This is the most detailed explanation of the core of Backstage you're likely to see, and the two only about third of the Backstage ecosystem overall. See Ben at BackStageCon, Nov 6th, 2023 in Chicago.

The three of us are back to discuss what a service mesh is and why it exists as a stand-alone thing. The result we come to is that you want this kind of network control and management as its own layer, not something that’s built into the stack. Check out the video if you prefer that.

What does a car manufacture need to do to speed up their software delivery cycle? Manufacturing is often finely tuned following lean and other principles, but the software development and delivery process, oddly, is not. In this episode, we talk about he last five years of software transformation at Jaguar Land Rover (JLR). We discuss the type of software JLR creates for itself, the need to change to transform (driven by quality and speed of delivery), putting CI/CD in place, challenges to change management (mostly about people), and the mismatch between finance and software.

Coté talks with Bryan Ross about fitting Kubernetes (and it's use) into the business strategy. Check out Bryan's YouTube channel for more Bryan.

"75% of IT and business executives say that their companies’ ability to compete is directly related to their ability to release quality software quickly" reads a recent Forrester Consulting report. If that’s the case, why are so many developer in large organizations have a bad developer experience? Paul Kelly wrote up the case for good DevEx and what it looks like for developers on the VMware Tanzu blog recently. In this episode, Cora and Coté talk with him about the blog. Paul also wrote two books on Visual COBOL so, naturally, we open up by talking about COBOL. Why did we ever need more? You can watch the original, streamed video if you like that kind of thing.

So you've built an app platform. And those pesky developers aren’t showing up to use. Or, worse, they grumble about it! Did you remember to tell anyone about it, to convince them to use it? You know: marketing! Also, they'll need to know how to use it. And you know what that means! Documentation. In this episode, Coté and Ben talk about the basics platform marketing: brand, principles, advocacy, internal conferences, and more. They also discuss the role of Backstage in making platforms better, as well as everyday developer life. You can also watch the video of this episode, if you prefer that kind of thing.

This week, Ben and Ed try to help Coté understand what the changes in RHEL open source development mean. We don't figure it out completely, but get close enough. Also, Ed tells us what Crossplane is. Finally, we briefly discuss two new reports from Gartner and Forrester that seek to define the cloud native application stack.

Right after Cloud Foundry Day 2023, Nick and Coté do a quick re-cap of the day. Taking place in Germany, there were many people from the German community, and elsewhere of course. Nick goes over his little talk which focused on Cloud Foundry usage and metrics. His recent post on The New Stack includes a lot of the same content. Keep an eye on the Cloud Foundry YouTube channel for recordings of all the talks, including Nick’s and Coté’s.

Cloud Foundry is one of the most mature, most proven platform as a service stacks. And it's open source! Ahead of CF Day on June 21st, 2023 (in person and live), Coté catches up with Ram Iyengar, Chief Evangelist at Cloud Foundry Foundation. They discuss Cloud Foundry's integrations with Kubernetes and related projects, organizations that use and contribute to Cloud Foundry, how Cloud Foundry fits into platform engineering think (and doesn't), the Cloud Foundry Foundation, and how Ram ended up being a developer advocate. Cloud Foundry Day is on June 21st, 2023 in Heidelberg, Germany. It's in person and online, so you can attend whether you're in person, or cozy at home. It's free to attend online.

In this episode, Cora and Coté talk with Abby Bangser about the platform maturity model draft that the platform working group at the CNCF has been working on. While the draft is a work in progress, the model the team is developed is extremely useful for thinking about how you build and run your platform team. Check out the interview, and if you’re interested in more, take a look at the draft paper. If you’re really full of beans, you can also contribute. You can also watch the video of this episode if you prefer. As Abby mentioned, you can find her by searching for Abby Bangser in most social and web places. She’s @a_bangser in Twitter, @abangser.bsky.social in Bluesky, @abangser in Mastodon, and, of course, in LinkedIn.

We talk about getting PCI compliance into Kubernetes, and other security think in the cloud native world. Securing Tanzu Application Service and Tanzu Application Platform. David Zendzian talks with Cora and Coté about what exactly “security” means in the cloud native context. They use his upcoming paper on PCI compliance as an example throughout.

In this episode, Coté is joined by Fouad Hamdi, to discuss a project he worked on to modernize of a 30-year-old mainframe app. Fouad provides a comprehensive breakdown of how he and his team at VMware Tanzu Labs approached this task, migrating a system relied on by over 3 million users from a mainframe infrastructure to a microservices architecture. Read the original blog post they discuss here. Details Fouad and Coté delve into the initial goals for mainframe modernization, the constraints, and past attempts at modernization that shaped the path they took. Fouad shares how they managed to migrate safely and at a rapid pace, all while maintaining the existing system's functionality. Listen as Fouad walks us through how the team leveraged the power of event storming workshops and Domain Driven Design (DDD) to understand the business domain and identify key areas for modernization. They discuss the challenges of working with older technologies like COBOL, and the strategies they used to bring business knowledge to a new generation of developers. They also explore how the team navigated complex issues such as coexistence between the old and new systems, and how they incrementally built the new system to avoid any disruption of service. Fouad shares invaluable insights into the importance of context in these modernization efforts, and the lessons they learned along the way. Whether you're a software engineer, an architect, or a business leader looking to modernize your own systems, this episode is filled with practical advice and lessons learned from modernizing a mainframe application. Tune in to learn from Fouad's experience and to understand how you can apply these lessons to your own mainframe modernization journey. More Read the original blog postFouad’s BlogFouad in LinkedIn
