Lambda (AWS Lambda)

AWS Lambda is a cloud service that runs your code automatically in response to events or triggers, without needing to manage servers. Think of it as a virtual worker that executes specific tasks only when needed, such as processing a file upload or responding to a user action. You provide the code, set the conditions for when it should run, and AWS handles the rest, scaling instantly to match demand. This allows for efficient, cost-effective, and scalable application development without worrying about underlying infrastructure.
