AWS Lambda is a serverless computing service that allows users to run code without managing servers. It automatically scales based on data input and is often used in big data processing and as a glue between AWS services. Lambda can also be used to build serverless websites and connect various AWS services, such as API Gateway, Cognito, and DynamoDB. Its flexibility allows for creative integration of different components, making it a powerful tool for developers.
