Cloud Computing Intermediate

What is Lambda Function (Cloud)?

An AWS serverless compute service that runs code in response to events without provisioning or managing servers.

AWS Lambda executes functions triggered by events: API Gateway requests, S3 uploads, DynamoDB changes, SQS messages, scheduled events, and more. You pay only for execution time (billed per millisecond) with no idle costs.

Functions have memory (128MB-10GB), timeout (up to 15 minutes), and concurrent execution limits. Cold starts (first invocation delay) can be mitigated with provisioned concurrency. Lambda supports Python, Node.js, Java, Go, Ruby, .NET, and custom runtimes via containers.
