Cloud-Native für .NET-Entwickler: Moderne End-to-End-Architekturen

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 Ganztages-Workshop zeigen Christian Weyer und Thorsten Hans anhand von verteilten Anwendungsarchitekturen und bewährten 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.

14. Disadvantages of Windows Containers • Bigger in size • longer push/pull times • Require more storage (affects Kubernetes & PaaS) • Higher resource consumption • Windows Containers & Hosts need more CPU & memory • Direct impact on infrastructure budged • Host & container OS must have same version (strict policy) • https://kubernetes.io/docs/concepts/windows/intro/#windows-os-version-support • Meaning you may end up with way more infrastructure Cloud-Native-Workshop Moderne End-to-End-Architekturen in der Praxis Cloud-Native Software 14 Myth Busting & Definitions
