sam deploy (optionally after sam package)
What is SAM Accelerate?
A feature set to speed up deployments by syncing code and resources faster, without full CloudFormation updates.
What does sam sync do?
Synchronizes code and infrastructure defined in your SAM templates to AWS.

S3ReadPolicy, SQSPollerPolicy, DynamoDBCrudPolicy.
How does SAM integrate with CodeDeploy?
It uses CodeDeploy for traffic shifting and validates deployments using pre/post traffic hooks.
What does AutoPublishAlias do in SAM?
Automatically publishes new versions on code updates and moves the alias to point to the new version.
