And of course we have incorporated all of that experience in the source code. The main features are now in place, and are getting better and better on a daily basis.

Tutorial: Backing up Kubernetes Clusters with K8up

One of the most common questions we got from companies moving to Kubernetes has always had to do with backups: how can we ensure that the information in our pods and services can be quickly and safely restored in case of problems?

A (Very!) Quick Comparison of Kubernetes Serverless Frameworks

Serverless is one of those hot topics that, as many others in our industry, looks a bit like a good old idea recycled and brought back to fashion. Yet Serverless (or “Function as a Service”) looks like a natural evolution to a movement that started more than a decade ago, when Heroku and Google App Engine came under the spotlight. (This blog post is the transcription of the presentation given at the CNC Switzerland meetup, May 9th 2019. Slides are available at the end of this page.)

How to leverage Kubernetes operators using the Operator SDK framework

Kubernetes has become an omnipresent platform to host cloud-native applications. As a rather low-level platform, it is often made developer-friendly by wrapping it into higher-level platforms, such as OpenShift (OKD), and by turning it into a managed service platform, such as APPUiO, which can be deployed to any cloud infrastructure.
