An excellent, and practical, post with tips on helping a team or organisation actually change its culture. Culture might be a central tenet of devops, but finding hands-on discussions can be challenging.

I’d wager most support organisations, including development teams, use a very traditional 3 tier support model. This post explains some of the weaknesses of that approach and explores an alternative; swarming.

An in-depth look at time-series data, and how you can use it across an organisation rather than just as a detail for a monitoring system.

The operations side of serverless is still a new field I feel, one of the specific areas worthy of discussion is security. This post provides a good overview of the current state of affairs and challenges to overcome.

Kubernetes as a large number of concepts, at various levels of abstraction. Deployments sit fairly high in the stack, and this post explains when and how they are used for gradual rollouts of containers.
