Serverless-Szenarien mit Azure Functions & Co. - Integration-as-a-Service

Wie bitte? Microsofts Azure-Cloud auf der W-JAX? Ja, in der Tat. Denn nicht immer muss oder soll es AWS oder GCP sein. Azure bietet mittlerweile eine holistische Plattform für so gut wie jede Cloud-Anforderung an. Auch und vor allem in den Bereichen Cloud-native und Serverless Functions investiert Microsoft sehr viel. In dieser Session zeigt Christian Weyer neben den Grundlagen vor allem typische Anwendungsszenarien für Azure Functions. Der Fokus soll dabei auf eventgetriebenen Integrationslösungen und Workflowszenarien liegen – hier bedarf es nicht immer Unmengen von Code, um ans Ziel zu kommen. Lehnen Sie sich also zurück und sehen Sie "die andere Cloud" in Action. Keine Angst vor Azure!
