Justin Garrison joins us to talk about Amazon’s silent sacking, from his perspective. He should know. He works there. Well, as of yesterday he quit. We discuss how the cloud and Kubernetes have transformed the way software is developed and deployed, the impact silent layoffs have on employees and their careers, speaking out about workplace issues (the right way), how changes in organizational structure can lead to gaps in expertise and responsibility which can lead to potential outages and slower response times.

By the way, we officially let the cat off out of the bag in this episode. Justin has joined the ranks here at Changelog and is taking over as the host of Ship It! Expect new episodes soon.

This week it’s storytime with Steve Yegge! Steve came out of retirement to join Sourcegraph as Head of Engineering. Their next frontier is Cody, their AI coding assistant that answers code questions and writes code for you by reading your entire codebase and the code graph. But, we really spent a lot of time talking with Steve about his time at Amazon, Google, and Grab. Ok, it’s storytime!

Rust efficiencies at AWS scale

Tim McNamara is known as New Zealand’s Rust guy. He is the author of Rust in Action, and also a Senior Software Engineer at AWS, where he helps other builders with all things Rust.

The main reason why Gerhard is intrigued by Rust is the incredible resource frugality. Fewer CPUs means less energy used, which is good for the planet, and good for the monthly bill. This becomes most noticeable at Amazon’s scale, when S3, Lambda, CloudFront and other services start adding Rust components.

Eight months ago, in 🎧 episode 49, Alex Sims (Solutions Architect & Senior Software Engineer at James & James) shared with us his ambition to help migrate a monolithic PHP app running on AWS EC2 to a more modern architecture. The idea was some serverless, some EKS, and many incremental improvements.

So how did all of this work out in practice? How did the improved system cope with the Black Friday peak, as well as all the following Christmas orders? Thank you Alex for sharing with us your Ship It! inspired Kaizen story. It’s a wonderful Christmas present! 🎄🎁

Matias Pan is a Staff Software Engineer at Lemon Cash, a crypto startup based in Argentina. Lemon infrastructure runs digital wallets & physical cards, which technically makes them a bank. How does Matias & his team think about enabling developers get code from their workstations into production? Remember, we are talking about a bank - a bad deploy is a big deal. And when a bad database migration goes out, what happens then?

Improving an eCommerce fulfilment platform

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.

Gunnar Holwerda (Engineering Manager) and Tom Pansino (DevOps Team Lead) share with us a few stories about how the teams at opensesame.com manage AWS operational complexity. The first link in the episode show notes are the slides that Tom & Gunnar prepared for this conversation. Check them out as you hear us speak about the Inverse Conway Manoeuvre, and why you should always go for the bananas.

A monorepo of serverless microservices

In this episode, Gerhard talks to his Skyhook Adventure friends: Alan Cooney, Saul Cullen & Wycliffe Maina. They are the ones that introduced Gerhard to the world of serverless in the context of Amazon Web Services. Gerhard shared his experience with remote work, how to ship software with confidence and consistency, and what to look for in infrastructure as code.

At the heart of Skyhook Adventure are adventure trips, and 2020 was not a good one for this business. As you can already tell, code and infrastructure was not the biggest challenge for this team. Having said that, serverless, microservices, a monorepo and the event-based architecture played a big part in successfully navigating the challenges.

This is a story about what happens when a good team allows itself to be guided by solid experience and keeps doing the right thing, long-term. It’s fun, real, and it applies to many.
