DevOps in a Serverless World, best practices and tools

You might think that moving to Serverless is going to hinder your ability to manage your apps but instead if you adopt the right approach, implement the right objectives, Serverless can instead be a wonderful opportunity to align business goals and development agility.

The presentation covers some SRE (Site Reliabity Engineering) practices such as SLOs and error budget and discusses how Google Cloud Functions, App Engine, and Cloud Run offer both the productivity of Serverless and the observability for proper DevOps.

1. @alexismp DevOps et Serverless Utopie ou opportunité? ALEXIS MOUSSINE-POUCHKINE DEVELOPER ADVOCATE GOOGLE CLOUD @ALEXISMP
2. @alexismp Serverless Operational Model No Server Management Fully Managed Security Pay only for usage Programming Model Service-based Open Auto-scale Event-driven
3. @alexismp Survey ! Serverless is about deploying : 1/ Functions, obviously! 2/ Applications, otherwise it’s just glue code... 3/ Containers ! (because Kubernetes)

25. @alexismp cloud.google.com Containers Everything at Google runs in containers • Gmail, Web Search, Maps, ... • MapReduce, batch, ... • GFS, Colossus, ... • Even GCP’s VMs run in containers! 2 billion containers per week
26. @alexismp cloud.google.com Functions Container to production in seconds One DevX Fully-managed or GKE Containers (can too be serverless) Applications Cloud Run Natively serverless
