Serverless avec Google Cloud : Comment mettre rapidement en production vos applications ?

Avec Thibault Ruaro: https://twitter.com/thibaultruaro

L'univers de l'hébergement Cloud est très vaste et nécessite de s'approprier de nouveaux paradigmes afin d'exploiter au maximum ces infrastructures.

Le Serverless est une solution Cloud qui permet de rapidement mettre en production vos applications :
le serveur et le runtime sont gérés directement par la solution permettant aux équipes de développement de se concentrer sur le code métier.

Que ce soit avec Google App Engine, la solution de PaaS (Platform as a Service) ou encore avec les Cloud Functions, la solution FaaS (Function As a Service) ou encore Cloud Run, GCP fournit un environnement et des outils pour être productif dans le Cloud.

Grâce à notre partenariat avec Google Cloud, Zenika est fier de proposer ce webinar de 1h autour du Serverless.

19. Serverless computing refers to the concept of building and running applications
    that do not require server management. It describes a finer-grained deployment
    model where applications, bundled as one or more functions, are uploaded to a
    platform and then executed, scaled, and billed in response to the exact demand
    needed at the moment.

27. Cloud Run
    Fully managed, deploy your
    workloads and don’t see the
    cluster.
    Cloud Run on Anthos
    Deploy into Anthos, run
    serverless side-by-side with
    your existing workloads.
    Knative Everywhere
    Use the same APIs and
    tooling anywhere you run
    Kubernetes with Knative.

28. Container contract
    Listen on 0.0.0.0 on port $PORT (default 8080)
    HTTP server must start < 4 min (timeout → 504)
    Request time < 60 min (default → 5 min)
    Stateless (in-memory file system, doesn’t persist)
    Computation only within request (No background activity)

29. Container resources
    1 vCPU per container instance (configurable to 4vCPU)
    512 MiB of memory up to a max of 8 GiB (configurable)
    80 concurrent requests per container (configurable 1-1000)
    1000 max containers by default (configurable 1-1000)
    Access to a Metadata Server

    Good fit
    Stateless
    HTTP request-response workloads
    Scale: way up, down to zero, bursty
    Any runtime: any language, any
    dependencies, etc
    Constraints
    Must use containers
    No background tasks
