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).
