Découvrir les Cloud Events avec Cloud Run

CloudEvents est une spécification de la CNCF ayant pour objectif d’améliorer la portabilité des événements publiés sur nos systèmes Cloud voir même Multi-Cloud.

Cloud Run est un produit Serverless de la Google Cloud Platform qui supporte cette spécification. Ainsi depuis Cloud Run, nous pouvons directement écouter des événements au format CloudEvents.

Nous vous montrerons des exemples d’implémentations avec des démonstrations.

6. 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.

24. “Eventarc provides an easier path to receive
    events. You don’t have to worry about the
    underlying infrastructure with Eventarc. It is a
    managed service with no clusters to set up
    or maintain. ”

27. ● Open Source Standard but quite new…
    ● CNCF healthy project: Spec (format & protocol) + SDKs + Integrations
    ● Good idea to define connectors (source & sink)
    ● Interoperable (supported by Knative/eventing)
    ● Superior Dev Experience thanks to a predictable format message
    ● Decouple apps (from infrastructure and configuration)
    ● Discoverability of event sources
    Our point of view

28. ● 👍 No longer lock-in with the supported trigger
    ● 😱 No news from AWS in this project
    “It is very similar to AWS’s CloudWatch Events functionality”
    ● 💪 Wide range of usage (Kafka, AMQP, Webhook)
    ● 🤔 Future of the Working Group
    ● 🚧 New goal: get a global vision of our event-driven system thanks to
    Workflow https://github.com/serverlessworkflow/specification/
    Next steps
