## AI overview

AWS Lambda Web Functions let developers deploy standard Node.js HTTP servers and frameworks such as Express, Hono, Fastify, and Next.js directly to Lambda. One warm execution environment can handle concurrent requests, and responses can stream; billing covers active CPU time and memory, with memory charged for the environment's lifetime. Multi-Region routing sends requests to the closest Region, and CloudFront can provide custom domains, edge caching, or AWS WAF. The service targets HTTP workloads including APIs, full-stack apps, microservices, server-side rendering, and streaming. It currently supports only Node.js and is available in five Regions: Northern Virginia, Ohio, Oregon, Tokyo, and Ireland. Existing Lambda functions are now called Lambda Event Functions, with no required changes. The excerpt notes that Google Cloud Run and Azure Container Apps offer a similar adapter-free web application model, with scale-to-zero and configurable concurrency.
