AWS Lambda

AWS Lambda allows codes to be run without provisioning or managing servers. StratusGrid uses AWS Lambda to provide customers with a serverless, scalable, fast, and reliable solution for running scripts. AWS Lambda enables StratusGrid the ability to architect event-driven solutions by allowing for these scripts to be invoked by CloudWatch and other AWS services. Each code is run and is automatically scaled according to your application. Customers are only charged for every 100ms that the customers’ code itself executes and the number of times the code is triggered.
