Redundant ways to use AWS Lambda

Local test enviroments : 

• (ServerlessApplicationModelSAM), 
• (ServerlessFramework|SLS)

SAM uses (RuntimeInterfaceEmulator|RIE), SLS uses ... buttfuckall, no one has a name for it, it's not RIE, but it does the same thing.

Alternatives are LocalStack, et al.

Deployment tools :

• SAM, 
• SLS, 
• (CloudDevelopmentKit|CDK), 
• (CloudFormation|CF) 

... they are all wrappers for CF ... and CF is just a wrapper for the AWS API, so the most minimalist approach turns out to be to script against the AWS API directly. 

Alternatives are Terraform, Ansible, et al.
