Serverless compute that runs code without managing servers
AWS Lambda is the pioneering and most popular serverless compute platform, executing code in response to events (API calls, S3 uploads, DynamoDB changes, scheduled tasks) without server provisioning. It's the foundation of serverless architecture on AWS. Lambda enables rapid development with pay-per-execution pricing, automatic scaling, and zero infrastructure management. It's central to modern event-driven architectures and is used for APIs, data processing, automation, and backend logic.
