When a developer spins up a virtual machine on AWS, that virtual machine could be purchased using one of several types of cost structures.

Serverless tools have come a long way since the release of AWS Lambda in 2014. Serverless apps were originally architected around Lambda, with the functions-as-a-service being used to glue together larger pieces of functionality and API services. Today, many of the common AWS services such as API Gateway and DynamoDB have functionality built in to
