      AWS Lambda 

     Documentation

AWS Lambda is a zero-administration compute platform for back-end 

web developers that runs your code for you in the AWS cloud and provides 

you with a fine-grained pricing structure. AWS Lambda runs your back-end 

code on its own AWS compute fleet of Amazon Elastic Compute Cloud 

(Amazon EC2) instances across multiple Availability Zones in a region, which

 provides the high availability, security, performance, and scalability of the AWS

 infrastructure.
