AWS

Lambda:--
Lambda is the serverless compute offering from AWS. It is event-driven.

CloudWatch or API Gateway etc can invoke Lambda to run to certain event or alarm.

Lambda is the FaaS - Function as a Service. It supports many languages. Like: Python , Ruby, C#, Node.js, Google Go etc

It is serverless in that you don't have to provision any EC2 instances. It can scale out and in automatically.
All you need to do is provide the code. It integrates seemlessly with AWS services like S3, DynamoDB etc. It is also used for automation to run scripts to perform actions like turning EC2 instances on or off etc.
