Building large-scale or even reasonably complex systems is made more difficult because the body of knowledge about how to do so is very distributed. The systems design primer is a great collection of resources with a clear educational focus.

Scale Summit is a great unconference event with a wide range of discussions about operations and infrastructure. This set of notes summarises some of those conversations.

Kubernetes is a complex distributed system with some a number of different moving parts that all need some level of monitoring. This 4 part series breaks some of that down, including a case study from a Kubernetes user.

I was pondering monorepos this last week and a good conversation ensued, with people with a variety of experiences and opinions. A good summary of the thread.

One of the advantages of infrastructure as code is that good practices can be documented in a way that makes reuse easy. This post shows how to apply various AWS security best-practices in your Terraform code.

Data storage at scale is all about trade offs. This post steps through resolving a large lag in a replicated MySQL setup after adding a new slave to the cluster.
