This repo has serverless sample code/templates/scripts that I found useful during my quest of learning how to build serverless applications.
SERVERLESS is not JUST LAMBDA
Serverless includes all the services in which the end user doesn't have to essentially manage/operate the "servers" on which the application/service runs. For ex: It could be services like AWS Fargate, AWS Kinesis, AWS Athena, Amazon SNS, Azure Functions etc.
