Serverless computing is a cloud execution model where developers run functions without managing servers or infrastructure. Cloud providers handle provisioning, scaling, and maintenance automatically. Functions execute on demand and scale instantly based on traffic, with billing based on actual usage rather than preallocated capacity.
Why it matters
Serverless reduces operational overhead and simplifies deployment, especially for event-driven or intermittent workloads. It allows teams to focus on application logic instead of infrastructure management.
Examples
Running AWS Lambda functions triggered by API Gateway or using Cloudflare Workers to handle edge logic. Lessons like Serverless Computing Explained explore this model.
