For our last 2022 Kaizen episode, we went all out:
All of this, and a whole lot more, is captured as GitHub discussion 🐙 changelog.com#433. If you want to see everything that we improved, that is a great companion to this episode.
What do you do when your infrastructure runs 1000 miles away and you only have access every 90 minutes? Find out from Andrew Guenther from Orbital Sidekick.
The ability to learn on the job has been a critical skill for David Beale throughout his career. Is the job market not allowing that anymore?
In your company, who designs the end-to-end developer experience? From design to implementation, what is the developer experience that you actually ship? Even though the average developer wastes almost half of their working hours because of bad DX, many of us don’t even know what that means, or how to improve it.
Kenneth Auchenberg is working at Stripe, building economic infrastructure for the internet. Gerhard found his perspective on Developer Experience Infrastructure (DXI) refreshingly simple, as well as very useful.
Few genuinely need a multi-cloud setup. There is plenty of advice out there which mostly boils down to don’t do it, you will be worse off. Vex.dev is a startup that provides APIs for video and audio streaming. The hard part is real-time combined with massive scale - think hundreds of thousands of concurrent connections. They achieve this by using a combination of Fly.io, AWS and GCP. Jason Carter, founder of Vex Communications, is joining us today to talk about the multi-cloud setup that vex.dev runs.
Today we are talking with Maikel Vlasman, technical lead for a large Dutch machine construction company, and a cloud engineer by heart. We cover self-updating GitLab & ArgoCD, Maikel’s thinking behind dev environment setup and a Kubernetes workshop that he is preparing for his team. The goal is to function as a true DevOps team with shared responsibilities.
This conversation started as a thread in our community Slack - link in the show notes. Thank you Maikel for being a long-time Changelog listener and for reaching out to us - we enjoyed telling this story.
From switching ISPs to migrating Amazon off Oracle, Pete Naylor knows which database to use.
Today we talk to Mark Ericksen about all the things that we could be doing on the new platform - this is a follow-up to episode 50.
Mark specialises in Elixir, he hosts the Thinking Elixir podcast, and he also helps make Fly.io the best place to run Phoenix apps, such as changelog.com. In the interest of holding our new platform right, we thought that it would be a great idea to talk to someone that does this all day, every day, for many years now.
We touch up on how to run database migrations safely, and how to upgrade our application config to the latest Phoenix version. We also talked about some of the more advanced platform features that we may want to start leveraging, like the multi-region PostgreSQL.
Danielle Lancashire is here to tell us how Fermyon cloud is built on top of nomad and EC2 and how they put it in a box with Kubernetes and WebAssembly.
Alex Sims, a Senior Software Engineer at James & James, an eCommerce fulfilment company, reached out to us about the Kaizen story of the third-party logistics (3PL) platform that he has been involved with for several years now.
The system delivered 16 millions of orders in 10 years, and 4.5 million in the last year alone. All the numbers are going up, and there is only so much that a single PHP monolith deployed as VM images can handle. So how do you even start thinking about the architectural improvements, and inspire everyone involved to move towards better?
We encourage you to look at the architectural diagrams in the show notes, especially the 10 year roadmap, and ask Alex for a blog post follow-up. While today’s episode was a good conversation starter, there is a lot that we did not have time to cover.
Verónica López, Kubernetes SIG Release tech lead & distributed systems engineer, joins Justin & Autumn to share her experiences deploying services at scale.
Git was designed to be distributed but there is a lot of gravity around GitHub. What does the model look like for a business that encourages you to run your own git server and what does the backend for gitea.com look like?
Gareth Greenaway from the Salt project joins us for a trip down memory lane with configuration management and why open source projects have changed over the past decade.
Tammer Saleh, founder of Super Orbital, a tiny team of exceptional Kubernetes engineers and teachers, is joining us today to talk about what is cool in the Cloud Native world. Yes, it’s the same Tammer that we had the pleasure of on shipit.show/31 - Is Kubernetes a platform?
In today’s episode, we also cover two great blog posts:
We wrap up with ✨ The Cool Wall of Cloud Native ✨
Today we are talking with Frederic Branczyk, founder of Polar Signals & Prometheus maintainer. You may remember Frederic from episode 33 when we introduced Parca.dev.
This time, we talk about a database built for observability: FrostDB, formerly known as ArcticDB. eBPF generates a lot of high cardinality data, which requires a new approach to writing, persisting & then reading back this state.
TL;DR FrostDB is sub zero cool & well worthy of its name.
Our today’s guest spent 4 days building a feature for his side project so that we could ship it together on Ship It!, while recording. The feature is called rave mode, and the context is Bass, an interpreted functional scripting language written in Go, riffing on the ideas of Kernel & Clojure. When the local build runs, you can now press r to synchronise the beats of your currently playing Spotify track with the build output. For a demo, see bass v0.9.0 release.
Please welcome Alex Suraci, a.k.a. vito, the creator of Concourse CI and Bass.
This episode is dedicated to the late John Shutt, the creator of Kernel.
Your ideas continue in Bass.
Thank you for getting them out into the world.
A few weeks ago, Jerod spoke with Liz Rice about the power of eBPF on The Changelog. Today, we have the pleasure of both Liz Rice, Chief Open Source Office at Isovalent & Thomas Graf, CTO & co-founder at Isovalent, the creators of Cilium.
Around 2014, Facebook achieved a 10x performance improvement by replacing their traditional load balancers with eBPF. In 2017, every single packet that went to Facebook was processed by eBPF. Nowadays, every Android phone is using it. Truth be told, if it’s network-related and it matters, eBPF is most likely a part of it.
Andrew Atkinson joins Autumn & Justin to tell them why folks should (and are) picking PostgreSQL as their database in 2024 and how to scale it.
This is the post-KubeCon CloudNativeCon EU 2022 week. Gerhard is talking to Matt Moore, founder & CTO of Chainguard about all things Knative and Sigstore.
The most important topic is swag, because none has better stickers than Chainguard.
The other topic is the equivalent of Let’s Encrypt for securing software.
This is our 5th Kaizen where we talk about the next improvement to changelog.com: we are now running on Fly.io and our PostgreSQL is managed. This is a migration that many were curious about, including Simmy de Klerk, the person that requested this episode.
After migrating all our media files to AWS S3 (check episode 40), we thought that this part was going to be easy. Plan met reality. Pull request 407 has all the details.
We want to emphasise the type of partner relationships that we seek at Changelog & why they are important to us, as well as to our listeners. Honeycomb & Fly embody the principles that we care about, and Gerhard thinks that we are currently missing a Kubernetes partner.
Jon “gzip enthusiast” Johnson joins us for a history lesson on compression & how it impacts everything from containers to Alpine.
Autumn and Justin are joined by Chris Swan to discuss tech industry trends like AI and sustainability, gamifying the software development process and motivating devs to write more secure code, OpenSSF Scorecards and how they offer a way to measure and improve the security and compliance of GitHub repos, the scoring system, and the security posture of a repository.
All of the health anxiety of early internet adopters traced back to WebMD’s self diagnosis. Some sysadmin’s on-call nightmares came from a different part of the site.
Bailey Hayes & Taylor Thomas from Cosmonic join the show for a look at WebAssembly Standard Interfaces (WASI) and trade-offs for portable interfaces.
Today we talk with two lovely folks from Transistor.fm: Jason Pearl, Senior Software Developer & Jon Buda, co-founder. Gerhard was curious to find out about their setup & how did it change with the launch of the new podcast website builder. After all, you have been hearing us talk about our setup for years, so it was high-time to challenge some assumptions and learn how another team is solving similar problems.
TL;DL: keeping it simple is at the root of smooth operations & stable systems.
In our 6th Kaizen, we talk with Jerod about all the things that we cleaned up after migrating changelog.com from a managed Kubernetes to Fly.io. We deleted the K8s cluster and moved wildcard cert management to Fastly & all our vanity domain certs to Fly.io. We migrated the Docker Engine that our GitHub Actions is using - PR #416 has all the details. We did a few other things in preparation for our secrets plan. Thank you Maikel Vlasman, James Harr, Adrian Mester, Omri Gabay & Owen Valentine for kicking it off in our Slack #shipit channel.
Gerhard’s favourite improvement: the new shipit.show domain.
One of our listeners, Andrew Welker, suggested that we talk about Klustered, so a few hours before David Flanagan was about to do his workshop at Container Days, we recorded this episode. We talked about all the weird and wonderful Kubernetes debugging sessions on Klustered, a YouTube playlist with 43 videos and counting.
We then talked about Rawkode Academy, and we finished with conferences. Good thing we did, because David almost forgot about KubeHuddle, the conference that he is co-organising next week. Gerhard is looking forward to talking at it! No, seriously, check it out at kubehuddle.com.
In this episode Justin and Autumn are joined by Mandi Walls to take you back to a time before the cloud. Before Kubernetes. When a/s/l was common and servers were made of metal. Back to the days of AOL to discuss how chat rooms worked.
I don’t think that you can imagine just how excited Gerhard was to find out that Audi, his favourite car company, has a Kubernetes competence centre. We have Sebastian Kister joining us today to tell us why people, followed by tech make the process.
The right thing to focus on is the genuine smiles that people give in response to something we do or say. That is an important SLI & SLO for reducing friction between silos.
How does this impact the flow of artefacts into production systems that design & build cars?
Paul Frazee joins the show to tell us all about how Bluesky builds, tests, and deploys mobile and web applications from the same code base.
