- 2. Programme Intro - Why Azure Functions qu’est ce que c’est Extensions à Azure Functions Dapr qu’est ce que c’est Azure Functions + Dapr
- 3. #DevoxxFR 3 Serverless doesn't mean there are no servers, it means let's think about servers...less.
- 4. Dans le cloud on est Event Driven on a besoin d’ Event Driven Architecture Développer des apps à base de microservice qui interagissent avec des services qui sont resilient et scalable De multiples langages de programmation C# Python Javascript … Stateless, Stateful, et utilisation de pattern tels que les functions, workflow, actor Le moins possible d’adhérence à la plateforme : on veut que notre code tourne partout
- 5. Azure Functions V3 - 4.0 public preview avec .NET 6 support Opensource Host écrit en .net core On peux écrire des functions en C#, F#, Java, Javascript, Python, Powershell
- 6. Tooling Azure Function Core Tools VS CODE et l’extension Azure Functions Github Codespace ou Devcontainer est pratique

- 17. Application Types Develop resilient, scalable, microservice-based apps that interact with services stateless, stateful, long-running, short-lived function-like Increasingly apps are polyglot. Written with different languages and frameworks
- 18. Microservice building blocks Standard APIs accessed over http/gRPC protocols from user service code http://localhost:3500/v1.0/state/inventory/orderkey http://localhost:3500/v1.0/invoke/myapp/method/neworder Runs as local “side car library” dynamically loaded at runtime for each service Service- to- service invocation State management Publish and subscribe Resource bindings and triggers Actors Distributed tracing Secrets HTTP API gRPC API Extensible Application code Any code or framework… Microservices written in
