• Like CloudFormation but much easier and more friendly
  • Generate complex CloudFormation from simple SAM YAML file
• Use YAML
• Supports anything from CloudFormation: (Outputs, Mappings, Parameters, Resources, ...)
• Only 2 commands to deploy to AWS
• Use CodeDeploy to deploy lambda functions
• Have functionality to run AWS Lambda, API Gateway, DynamoDB locally
