This document provides an overview of AWS Serverless Application Model (SAM) which is a framework for building and managing serverless applications. SAM allows defining the architectural components of a serverless application in a SAM template and managing the application lifecycle through the SAM CLI. It describes how SAM transforms CloudFormation templates to deploy serverless resources like AWS Lambda functions, API Gateway APIs, and DynamoDB tables. The document also outlines the various commands of the SAM CLI used for local development and testing as well as deploying serverless applications.

DeploymentPreference:
Type: LinearXPercentEveryYMinutes
Traffic to new version will linearly increase in steps of X percentage every Y minutes. Ex:
Linear10PercentEvery10Minutes will add 10 percentage of traffic every 10 minute to complete in 100
minutes.
Type: CanaryXPercentYMinutes
X percent of traffic will be routed to new version for Y minutes. After Y minutes, 100 percent of traffic will be
sent to new version. Some people call this as Blue/Green deployment. Ex: Canary10Percent15Minutes will
send 10 percent traffic to new version and 15 minutes later complete deployment by sending all traffic to
new version.
