What is the difference between a serverless function and a lambda function?

Question

I am working with CloudFormation and I am a bit confused between serverless Function and Lambda function, like when to use aws::serverless::function and when to go with aws::lambda::function

Answer 1

If we see, there is no conceptual difference between serverless and lambda functions.

AWS::Lambda::Function is the syntax of Cloudformation to define AWS Lambda function whereas AWS::Serverless::Function is AWS SAM syntax which creates lambda function internally in CloudFormation.

In the initial stage of Lambda, there were some problems with developing serverless applications because of the complexity of writing CloudFormation for API gateway and Lambda. So later AWS came up with AWS SAM to overcome complexity in defining CloudFormatiom and also an alternative to Serverless Framework.
