AWS has launched Lambda Web Functions, a new serverless compute option designed to run HTTP applications directly without custom adapters or configuration. Developers use familiar Node.js frameworks such as Express and Hono to build AI inference endpoints, streaming APIs, microservices and server-side rendered applications.
Each execution environment handles multiple concurrent requests, reducing cold starts and improving response times. The service supports automatic scaling, multi-Region routing, VPC connectivity and native HTTP streaming.
Its pricing separates active CPU usage from time spent waiting on external services, helping organizations manage costs. Existing Lambda functions remain unchanged under the new Event Functions name.
