Cloud-Native: Definition, Praktiken & Patterns

Cloud-Native bedeutet nicht zwangsläufig Kubernetes oder gar Public-Cloud. Vielmehr definiert Cloud-Native eine Reihe von Attributen, die es beim Design und der Implementierung von verteilten Anwendungen zu beherzigen gilt. In diesem Vortrag räumen Christian Weyer und Thorsten Hans auf pragmatische Art und Weise mit den Begrifflichkeiten auf und diskutieren Praktiken, wie man moderne Cloud-Native Anwendungen entwerfen und umsetzen kann. Zudem zeigen sie praxiserprobte und bewährte Architektur-Patterns, mit denen essenzielle Themen wie Robustheit, Skalierbarkeit, Überwachbarkeit, und Konfigurierbarkeit ganzheitlich adressiert werden können. Egal ob lokal, im privaten Rechenzentrum oder in der öffentlichen Cloud:  als .NET-Entwickler ist es an der Zeit, sich Cloud-Native anzuschauen.
