Lambda

AWS Lambda is a serverless computing service that runs code in response to events without requiring you to provision or manage servers. It automatically scales applications by running code in response to triggers like HTTP requests via API Gateway, file uploads to S3, or database updates. Developers write functions in supported languages like Python, Node.js, or Java, and Lambda handles the underlying infrastructure.

Also known as: AWS Lambda, Lambda Functions, Serverless Functions, Function as a Service, FaaS

🧊Why learn Lambda?

Developers should use AWS Lambda for event-driven applications, microservices, and backend processing where scalability and cost-efficiency are priorities, as it charges only for compute time used. It's ideal for tasks like real-time file processing, data transformation, and building APIs, reducing operational overhead compared to traditional server management.
