Serverless Containers with Cloud Run Mete Atamel Developer Advocate at Google @meteatamel 

Intro 

Operational Model Programming Model No Infra Management Managed Security Pay only for usage Service-based Event-driven Stateless Serverless 

Containers Any language Any library Any binary Ecosystem of base images .js .rb .go .py .sh … 0 1 0 1 0 0 1 1 1 

Containers Flexibility Serverless Velocity 

Container to production in seconds Natively Serverless One experience, where you want it Cloud Run Bringing serverless to containers 

Container to production in seconds Just ‘deploy’ Any stateless container Any language, any library URL in seconds 

Natively serverless Focus on writing code Scale up fast Scale down to zero Pay for exact usage No servers to manage 

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. One experience, where you want it 

Basics 

HTTPS Endpoint Public • Website • API endpoint Private • Internal services • Async tasks • Mobile backend • Webhook 

Container contract Listen on 0.0.0.0 on port $PORT (default 8080) HTTP server must start < 4 min (timeout → 504) Request time < 15 min (default → 5 min) Stateless (in-memory file system, doesn’t persist) Computation only within request (No background activity) 

Container resources 1 vCPU per container instance (non-configurable) 256 MiB of memory up to a max of 2 GiB (configurable) 80 concurrent requests per container (configurable 1-80) 1000 max containers by default (configurable 1-1000) Access to a Metadata Server Sandboxed by gVisor 

Pay per use CPU / Memory / Requests 100ms 

Concurrency: up to 80 concurrent requests concurrency = 1 concurrency = 80 

Billable time Instance Billable Time Request 1 Start Request 1 End Request 2 Start Request 2 End Instance Time Billable Non-billable 

Other use cases
