GCP Cloud Run

Specialized skill for building production-ready serverless applications on GCP. Covers Cloud Run services (containerized), Cloud Run Functions (event-driven), cold start optimization, and event-driven architecture with Pub/Sub.

Principles

• Cloud Run for containers, Functions for simple event handlers
• Optimize for cold starts with startup CPU boost and min instances
• Set concurrency based on workload (start with 8, adjust)
• Memory includes /tmp filesystem - plan accordingly
• Use VPC Connector only when needed (adds latency)
• Containers should start fast and be stateless
• Handle signals gracefully for clean shutdown
