Packaging is always a hot topic. This post makes a convincing argument that the state of python packaging has improved measurably over the last few years.

A great post on building highly available database clusters, in this case a pool of MySQL replicas supported by HAProxy. Lots of code samples and demos.

Puppet 4 has been available for a while now with some useful new features like a type system and improvements to error messages, performance and more. A good list of gotchas for anyone upgrading.

Consul and more generally service discovery is a key part of many modern architectures. This post covers some of the things learned from running Consul for a while, including managing load, monitoring and auditability.

A good introduction to using recent features in Jenkins to build a modern pull-request centric test pipeline using the new Jenkinsfile.

A good look at how updates from package repositories can lead to larger Docker containers, why this isn’t desirable and what you can do about it.

Autoscaling is a key part of taking advantage of moving to a cloud environment. This post delves into why and covers some typical autoscaling strategies.

A discussion of the importance of automation and standards as teams scale out with more and more services. How do you avoid the microservices version of works on my machine?
