Was genau ist Serverless und was sind sinnvolle Anwendungsszenarien für Serverless Applications? In welchem Zusammenhang stehen dabei die Akronyme IaaS, PaaS, Baas und FaaS? Wir sprechen über „Stolperfallen“ und „Wie man’s richtig macht“.

3. Was ist die Idee
von Serverless?

4. #WISSENTEILEN
Run code, not servers
Serverless Function: Entwickler schreibt eine Business-
Funktion, „bundled“ diese mit den entsprechenden
Abhängigkeiten (LIBs) und lädt sie in die Cloud.
Serverless Environment: Führt die Funktion bei „Aufruf“ in
der passenden Runtime effizient, flexibel und hoch skalierbar
aus.
“

5. #WISSENTEILEN
No machines, VMs or containers*
Entwickler: Fokussiert sich ausschließlich auf die
Umsetzung der Business-Logik und das Erstellen des
Function-Bundle.
Cloud Provider: liefert und maintained rundum-sorglos
Umgebung für die Serverless Functions, inklusive etwaiger
Cloud Services (z.B. Storage, DB, Streaming, AI).
