What is Amazon Lambda?
💡 Model Answer
Amazon Lambda is a serverless compute service that runs your code in response to events and automatically manages the underlying compute resources. You upload your code as a Lambda function, specify triggers (e.g., API Gateway, S3, CloudWatch), and Lambda executes the function, scaling the number of instances based on incoming traffic. You pay only for the compute time consumed, and there is no need to provision or manage servers. Lambda supports multiple runtimes (Node.js, Python, Java, Go, .NET, Ruby, etc.) and integrates with many AWS services for building event‑driven architectures.
