Several posts this week with content from workshops, classes and training sessions. I know just how much effort it takes to put together high-quality learning material like that and I’m super appreciative and happy that folks are increasingly making this content freely available online.

The STELLA report from the SNAFU catchers consortium was published this week and makes interesting reading for anyone working on incident response or running large-scale systems. It contains writeups of several failures involving common technologies, delves into the theory and provides useful recommendations.

An excellent take on why monitoring is changing in the face of the adoption of cloud native platforms and microservice architectures. Nicely ties the co-evolution of the spaces together.

A good take on why Kubernetes is interesting. The point about having a single database of the state of all of your applications is super powerful in my view.

An excellent set of resources for anyone wanting to understand distributed systems. A nice, and not overlong, list of important books, papers and blog posts.

An interesting look at the numbers behind the growth of hyper-scale public cloud provider datacenters, and why the idea that everything will rapidly move to the public cloud might play out more slowly.

Assessing risk, and using that assessment to help design systems or processes, is a useful skill. It’s critical to avoid under (or over) investment in securing systems in particular. This freely available workshop content serves as a great introduction to risk assessment fundamentals.

A nice detailed look at how docker handles failure of containers, looking at signals, exit codes, restart policies and health checks.
