CodeDeploy deployment types

• CodeDeploy is a deployment service that automates application deployments to EC2 instances, on-premises instances, serverless Lambda functions, or ECS services.

• You can deploy a nearly unlimited variety of application content, including:

  • Code

  • Serverless AWS Lambda functions

  • Web and configuration files

  • Executables

  • Packages

  • Scripts

  • Multimedia files

CodeDeploy compute platforms

• EC2/On-Premises:

  • Describes instances of physical servers that can be EC2 cloud instances, on-premises servers, or both.

  • Applications can be composed of executable files, configuration files, images, and more.

• Lambda:

  • Used to deploy applications that consist of an updated version of a Lambda function.

  • It manages the Lambda function in a serverless compute environment made up of a high-availability compute structure.

• ECS:

  • Used to deploy an ECS containerized application as a task set.

Blue/Green deployment on an AWS Lambda compute platform

• You must choose one of the following deployment configuration types to specify how traffic is shifted from the original AWS Lambda function version to the new AWS Lambda function version:

  • Canary (Shifted in two increments):

    • Specify:

      • Percentage of traffic shifted in the first increment.

      • Interval before the remaining traffic is shifted in the second increment.

  • Linear (Shifted in equal increments with an equal number of minutes between each increment):

    • Specify:

      • Percentage of traffic shifted in each increment.

      • Number of minutes between each increment.

  • All-at-once (Shifted all at once)
