This skill helps to walk you through the Creation of AWS Lambda function by step by step assistance. AWS Lambda is an event-driven, serverless computing platform provided by Amazon as a part of Amazon Web Services. It is a computing service that runs code in response to events and automatically manages the computing resources required by that code. AWS Lambda is a compute service that lets you run code without provisioning or managing servers.
