AWS Lambda is a compute service that runs your code in response to events and automatically manages the underlying compute resources for you. You can use AWS Lambda to extend other AWS services with custom logic, or create your own back-end services that operate at AWS scale, performance, and security. AWS Lambda can automatically run code in response to modifications to objects in Amazon S3 buckets, notifications sent from Amazon SNS, messages arriving in Amazon Kinesis streams, or table updates in Amazon DynamoDB. »
