AWS Lambda

AWS Lambda is a serverless compute service that enables users to run code in response to events without provisioning or managing servers. Users write functions in various programming languages, and Lambda executes these functions automatically in response to triggers such as changes in data, HTTP requests, or messages from other AWS services. Lambda scales automatically based on the number of incoming events and charges only for the compute time consumed, making it a cost-effective solution for running applications and automating workflows. It is widely used for building event-driven architectures, microservices, and real-time data processing applications.
