Unter Infrastructure verstehen wir die Kombination der beiden Disziplinen, die für den flexiblen und zuverlässigen Betrieb von Systemen in Rechenzentren benötigt werden: einerseits das Design, die Installation und Konfiguration der Server-Infrastrukturen, andererseits die tägliche Betreuung dieser Systeme. Unser Fokus liegt auf Hochverfügbarkeit und -skalierbarkeit, Migrationen, Cloud und Open Source Data Center Management. Dabei verwenden wir innovative Technologien, mit Akzent auf Open Source. Durch die Verzahnung mit den Entwicklungsteams können wir die Infrastrukturen sehr präzise auf die entwickelte Software abstimmen (DevOps).

Welcome To The Container Jungle: Docker vs. containerd vs. Nabla vs. Kata vs. Firecracker and more!

2020-04-08T09:59:20+00:00

Which Container runtime do you use? Classics like Docker and containerd, or have you tried VM-based projects like Nabla, Kata or Firecracker? In this blog post, we compare more than ten container runtimes and classify them based on standards like OCI, Kubernetes’ CRI and CNI.

Welcome to the Jungle! Not a day goes by without the introduction of a new tool or framework that you should use in your container and orchestration setup. Well, you’

Hype Meets Harsh Reality: Microservices in the Wild Part 2

2020-04-03T14:25:53+00:00

Everyone wants to leave monoliths behind for new and shiny microservices these days. We have a look at the implications this had for our real-world project and why you would (not) want to go down that road. Part 2 lists the changes that actually happened.

This is the second part of a three-part series. We cover a real-life microservice migration with all its flaws and benefits. In the first part, we described why we sa

Istio: Transparent Multicluster

2020-03-09T17:37:33+00:00

Like all service meshes Istio tries to move some common network functionality into the infrastructure layer. Istio also allows some more complex features like Multicluster and multi mesh. In this blog post we will take a deeper look how we can use Istio multicluster for transparent failovers.

Istio is one of the many service mesh implementations out there. There is a very nice overview of the different service mesh implementations by INNOQ. Like all servic
