There's been a lot of talk about controlling cloud costs by bringing workloads back to the datacenter, you know, private cloud. The three of us discuss what's going on here. Also, surveys consistently show that only about half of developers are doing continuous integration (CI), and fewer are doing continuous delivery (CD). Can that be real? Ben doesn't think so. We also discuss how secure software supply chain thinking might change the tight coupling between CI/CD, making that slash back into a wall between the two: CI|CD. Also, Ben reveals his cartography background.
If subscribe to our show, you'll definitely be interested in the golden path series of talks this year. Check them out, for free, at SpringOne.io. Also, the CFP for SpringOne 2023 is open now, apply!
As ever, with your three friends: @egrigson, @benbravo73, & @cote.

You've been asked to build a cloud native cloud platform. The developers need some containers, probably some orchestration. So, what do you now? In this episode, Coté talks with ITQ's Robert Kloosterhuis about just this topic. Drawing on Robert's background as a virtualization admin and now, the Tanzu portfolio of stuff, they go through the type of thinking and work ITQ does with customers. Also, some tips on getting around Amsterdam for the people coming in for KubeCon EU.
Check out the live recording in video form, if you prefer that kind of thing.

The CNCF has a new kubernetes survey out and it has some interesting findings. We discuss several of them and our takes on them. Also, fresh back from cfmgmtcamp in Ghent, Coté talks about a new entrant in the configuration and release management space, System Initiative. 
As ever, with your three friends: @egrigson, @benbravo73, & @cote.
Here's the original video we streamed live if you're into that kind of thing.

In this episode, we check in on the Spring community by looking at the most recent State of Spring survey. While in survey land, we look at the Dynatrace Kubernetes in the Wild study: what are the top languages used in kubernetes, and how is on-premises use shaping up> Also, SpringOne was great, and now there's so much more of it each week until the next SpringOne this fall. And, check out how smooth Ben is at picking up MC duties when Coté's internet stops working.
Here is the original, unedited video stream if you're into that kind of thing.
Apologies that this episode is a week late posting. Coté got busy.

What's the deal with low code? After discussing current IT spending forecasts, Ed, Ben, and Coté discuss some recent thinking on how low code seems to fit into your business. We also discuss the organization structures needed for doing platform engineering and all that.
As ever, with your three friends: @egrigson, @benbravo73, & @cote.
IT forecast Worldwide IT spending is projected to total $4.5 trillion in 2023, an increase of 2.4% from 2022, according to the latest forecast by Gartner, Inc. This is down from the previous quarter’s forecast of 5.1% growth. While that’s declined, software and IT Services still have a lot of growth, hardware is pulling growth down: “The software and IT services segments are projected to grow 9.3% and 5.5% in 2023, respectively. The devices segment is forecast to decline 5.1% this year as both consumers and enterprises lengthen device refresh cycles.” Summary from Coté's newsletter.
What's up with "low-code" - what is Ed seeing, what does Ben think?
On Organizational Structures and the Developer Experience - If you’re working on developer tools, you need a different org structure than working on public cloud services. // “The reality is that org structures that have been designed to iterate and produce services at scale are not likely to satisfactorily address gaps between the services that negatively impact developer experiences without at least some change. If there’s no appetite for that, progress is likely to be limited.”

2023 Predictions and Hopes

Tuesday Dec 13, 2022

Tuesday Dec 13, 2022

It’s the last episode of the year so the three of us go over not only predictions in the cloud native space, but also our hopes for what happens. Also, there’s special guest ChatGPT on its predictions and a surprise piece of advice for New Year’s Day.
In the original video of this recording, at the end you get a bonus overview of GNOME from Ben.
A bit of a spoiler for you: platform engineering, more edge, consolidation of the app and kubernetes stack and platforms. Also, a shocking hope about GNOME (Linux desktops)!

Wednesday Dec 07, 2022

In this episode, we discuss the use of accelerators in the Tanzu Application Platform to help developers start programming quickly and efficiently. We also touch on some of the developer-focused announcements made at the recent AWS re:Invent conference. Finally, we have a discussion about ChatGPT experiments and their potential to reduce the amount of tedious work for office workers. Ben expresses some concerns about the technology, but Coté offers a compelling argument for its usefulness.†
Be sure to check out Ben’s new talk about Backstage in the Tanzu Application Platform GUI including: Accelerators (code templates), secure software supply chain visualization, API documentation, and more!
If you prefer video, here is the original recording, it has some bonus monster truck material: 
Links discussed in the show:
We talk about Ben’s recent video on templates (“accelerators”) in the Tanzu Application Platform. Also, we discuss the supply chain demo he does in that same video.
AWS Re:Invent news. Another 2 hr keynote with plenty of new services, many on the data side of things, plus the usual new EC2 instances. We talk about CodeCatalyst and AppComposer. Check out last week’s Software Defined Talk overview for more.
ChatGPT - an AI powered bot that’s been in my timeline a few times this week. From the same people that provide Dall-E, AI assisted drawing from natural language. SpectroCloud gave it a Kubernetes focused interview and it did pretty well. This feels like Boston Dynamics showcasing their robot inventions, in that it simultaneously amazes the public at large and scares them in equal measure. Unfortunately it doesn’t respond to ‘Shall we play a game?’ (for those that remember War Games and WOPR) - that would have been a cool Easter egg! See Coté’s experiments and take on it too.
† This week’s description written by ChatGPT with the prompt: “Can you write a podcast episode summary for me? We talked about some developer tools that help start programming (called accelerators) in our own product (the Tanzu Application Platform), then about a few developer things at AWS re:Invent. And then Coté talked a long time about ChatGPT experiments and his theory about how it can help reduce office worker toil. Ben was a bit scared.”

There was a lot going on at VMware Explore Europe last week, so we focus in on the Tanzu related stuff. Then: we do our usual check-in on platform engineering; a brief magic quadrant tour; see if there's any lessons to learn from Twitter the company; and close out discussing VMware's recent open source supply chain survey.
VMware Explore EU:
Cindy's round-up.
Tanzu Kubernetes Grid 2.1 - including support for Oracle Cloud.
Tanzu Mission Control - getting air gap stuff working (not out yet?).
Tanzu Service Mesh Advanced - roadmap announcements about: auto-discovering kubernetes and VM things; integrating with TAP to do security policy stuff; adding in running config stuff out of git (for, you know, GitOps).
Aria Graph, GA (previewed/announced in US): "Today at VMware Explore Europe, VMware is announcing the availability of a new freemium offering of VMware Aria Hub powered by VMware Aria Graph. This new free tier offering enables customers to inventory, map, filter, and search resources from up to two of their native public cloud accounts in either Amazon Web Services or Microsoft Azure."
More stuff: Bitnami updates, sovereign cloud stuff (working with partners to stand-up Tanzu in regional clouds).

We're past the "DevOps is Dead" phase, which is nice.
I think we can say "Developer Experience" without feeling dorky too. Even "DX."
New public cloud MQ, for IaaS+PaaS. Rank (first to last): AWS, Microsoft, Google, Alibaba, Oracle, IBM, Tencent, Huawei.
Transforming Twitter:
Finally, an example of the "pathological" column in the Westerum table.
