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).

4 Ways to Manage Your OpenStack Secrets with Terraform and git

2018-11-29T09:49:00+00:00

Terraform and OpenStack provide some clever ways of authenticating to OpenStack and configuring your clouds. This article shows you four easy ways so you never have to worry about accidentally uploading secrets to places where they shouldn't be.

Uploading secrets (i.e. passwords and usernames) to version control is an obviously terrible idea. Yet, there are almost 450,000 commits to github for the search term
