What are the benefits of serverless architecture?

Serverless architecture provides compelling benefits: (1) No server management — developers focus entirely on business logic, not infrastructure; (2) Automatic scaling — handles zero to millions of requests without configuration; (3) Cost efficiency for variable workloads — pay only for execution time, not idle capacity; (4) Faster time to market — skip infrastructure provisioning, jump straight to coding features; (5) High availability — built into the platform across multiple availability zones; (6) Reduced operational complexity — no patching, capacity planning, or on-call for infrastructure; (7) Event-driven integration — rich ecosystem of event sources enables loosely coupled architectures; (8) Language flexibility — multiple runtime support; (9) Built-in monitoring — CloudWatch, X-Ray integration out of the box; (10) Resilience — functions retry failed invocations automatically for async triggers.
