Read more“Kubernetes is the Linux of the cloud”This quote by Kelsey Hightower during the Kubecon 2017 in Austin emphasize the rise of Kubernetes among modern cloud infrastructures. This rise is partly driven by the developers community, but also by the web giants such as Google, Amazon, Alibaba or Red Hat who have invested a lot on this technology, and keep contributing to its improvement and smoothening its integration to their respective ecosystems.

The Brain-Eye Law: To a certain extent, observational power can compensate for mental weakness. Jerry Weinberg "I received your email. I get what you want to do. But, what's the goal?"

Read moreA few months ago our friends Guillaume Lefevre and Etienne Coutaud made an appearance at the 2017 KubeCon to present their work on a monitoring solution based on Prometheus and Grafana. (The video can be found here) A bit over a month later, we faced a problem in production, the platform started to behave abnormally. The graphs showed bursts in metrics which was unusual and some people were wondering if a deployment could have changed something in the configuration and triggered the problem. Even if…
