AWS re:Invent 2022 - Building real-world serverless applications with AWS SAM (SVS303) 

I don't completely agree with this, especially as regards DynamoDB. You can pass the table name in to the lambda thru an environment variable. However, do you really want the table (and all the data in it) to go away if the stack is destroyed?

now it would be aws cdk (even less typing) and there is cdktf (CDK for Terraform)

You do NOT want to write CloudFormation yourself. It's a terrible experience, even worse than writing terraform. Use CDK.

I find it a lot easier to learn when it's not just slides. I prefer to see the speaker.
