An interesting look at how AWS uses time-sharing to allocate CPU cycles to Lambda functions, and how higher-memory also equates to more available CPU.

A great, detailed, post on building a development infrastructure for a large slow running test suite. The main things I like where stepping through the constraints of the system, context at the time and eventual design decisions made.

Take a practical look at the different strategies to deploy an application to Kubernetes. We list the pros and cons of each strategy and define which one to adopt depending on real world examples and use cases.
Tools
Propone is a very interesting looking project which provides a tool for writing network-wide routing policy which can generate a highly scalable, and completely distributed eBGP implementation for every device in the network
