SRE Weekly Issue #96

Here’s the recording of my Velocity 2017 talk, posted on YouTube with permission from O’Reilly (thanks!). Want to learn about some gnarly DNS details?

I fell in love with this after reading just the title, and it only got better from there. Why add debug statements haphazardly when an algorithm can automatically figure out where they’ll be most effective? I especially love the analysis of commit histories to build stats on when debug statements were added to various open source projects.

Julia Evans is back with another article about Kubernetes. Along with explaining how it all fits together, she describes a few things that can go wrong and how to fix them.

In this introductory post of a four-part series, we learn why chaos testing a lambda-based infrastructure is especially challenging.

I love the idea of a service that automatically optimizes things even without knowing anything about their internals. Mmm, cookies.

What we are releasing is unfortunately not going to be readily consumable. It is also not an OSS project that will be maintained in any way. The goal is to provide a snapshot of what Lyft does internally (what is on each dashboard, what stats do we look at, etc.). Our hope is having that as a reference will be useful in developing new dashboards for your organization.

It’s not a secret since they published a paper about it. This is an intriguing idea, but I’m wondering whether it’s really more effective than staging environments tend to be in practice.
