Cloud-Native-Workshop: Moderne End-to-End-Architekturen in der Praxis

Ob Modernisierung oder Neuimplementierung: heutzutage soll es Cloud-Native sein! Doch was bedeutet Cloud-Native eigentlich, und was bedeutet es nicht? Müssen es wirklich immer und überall zustandslose Microservices sein? In diesem Ganztagesworkshop zeigen Christian Weyer und Thorsten Hans anhand verteilter Anwendungsarchitekturen und bewährter Patterns, wie Sie Cloud-Native-Anwendungen erstellen können. Durch praxisorientierte Beispiele werden .NET-Architekten und -Entwickler die unterschiedlichen Herausforderungen aufgezeigt und pragmatische Lösungswege diskutiert. Egal ob Sie als Ziel die lokale Infrastruktur, ein privates Rechenzentrum oder eine Public-Cloud wie Azure haben: Bereiten Sie sich und Ihr Team darauf vor, Anwendungen anhand essenzieller Cloud-Native-Attribute wie Konfigurierbarkeit, Überwachbarkeit, Robustheit, und Skalierbarkeit zu designen.
