What is the difference between a Serverless Function, and a Lambda Function

Question

I am playing around with the Cloudformation Serverless Transformation, and am trying to figure out how and when to use AWS::Serverless::Function or AWS::Lambd

Answer 1

Framework wise there is not much difference between both however, there are minor difference technically as below

Serverless: It creates the IAM role, S3 Bucket, Cloudformation Template, create, update & deploy the code. Can Invoke the program from command.

One more important point, when we would like to delete the function and all associated services like S3, IAM role etc, that can be done using a single line command. In AWS Lambda, we need to manually remove each service one by one

AWS Lambda: It allows snippets of code to execute in response to triggers caused by activity from other AWS resources such as an AWS CloudWatch alarm, changes in a NoSQL table as DynamoDB, an upload event in an S3 bucket, etc.

AWS Lambda function has limits and it is recommended that you keep code size down and break up bigger function to smaller ones.
