Serverless container platform for stateless applications

Core Idea: Cloud Run is Google Cloud's serverless compute platform that automatically scales stateless containers, charging only for the resources used during request processing with zero cost when idle.

Key Elements

• Key Features

  • Fully managed serverless environment
  • Automatic scaling from zero to many instances
  • Pay-per-use billing model (compute resources used)
  • Native container support (Docker)
  • HTTP/HTTPS request handling
  • Background and scheduled tasks support
  • Integrated with Google Cloud's security model

• Technical Specifications

  • Supports containers built for x86-64 architecture
  • Maximum request timeout: 60 minutes
  • Memory allocation options: 128MB to 32GB
  • CPU allocation options: 1-8 vCPUs
  • Concurrent requests per instance: configurable
  • Instance startup time: typically seconds
  • Container size limit: 10GB
  • Environmental variable and secret integration

• Use Cases

  • API backends
  • Web applications
  • Microservices
  • Event handlers and webhooks
  • Scheduled jobs
  • Data processing tasks
  • Automation tools deployment

• Implementation Steps

  1. Containerize application with Dockerfile
  2. Ensure container listens on PORT env variable (required)
  3. Deploy via gcloud CLI or Console
  4. Configure autoscaling parameters
  5. Set up service accounts and IAM permissions
  6. Connect to other Google Cloud services (optional)

• Code Example

# Basic Cloud Run deployment command
gcloud run deploy SERVICE_NAME \
  --image=CONTAINER_IMAGE \
  --platform=managed \
  --region=REGION \
  --allow-unauthenticated \
  --port=PORT_NUMBER \
  --cpu=1 \
  --memory=512Mi \
  --min-instances=0 \
  --max-instances=10 \
  --set-env-vars="ENV_VAR1=value1,ENV_VAR2=value2"
