Lambda Aliases

• To alias a Lambda Version. For example:
  • v1 => dev
  • v2 => test
  • $LATEST => prod
• Aliases are mutable
• Can assign weights for Blue / Green deployment support. For example:
  • Same alias but 50% go to v1 and 50% go to v2
  • For automatic traffic shift, see Lambda and CodeDeploy
• Note: alliases cannot reference other aliases
