Vercel Reliability Patterns Overview Build fault-tolerant Vercel deployments with circuit breakers, retry logic, graceful degradation, and instant rollback integration. Addresses reliability at two levels: function-level resilience (protecting against dependency failures) and deployment-level resilience (protecting against bad deploys). Prerequisites - Vercel project deployed to production - Understanding of failure modes in serverless - External dependencies (databases, APIs) identified Instructions Step 1: Circuit Breaker for External Dependencies Important for serverless: Circuit breaker s…
