AWS CodeDeploy

An AWS service that automates application deployments to EC2, on-premises servers, Lambda, and ECS using an appspec file.

Definition

CodeDeploy supports in-place and blue/green deployments, deployment configurations (AllAtOnce, HalfAtATime, OneAtATime, canary and linear for Lambda/ECS), lifecycle hooks, and automatic rollback on alarms or failure.

Example

A Lambda deployment uses LambdaCanary10Percent5Minutes and rolls back if a CloudWatch alarm fires.

Exam tip

Lifecycle hooks and rollback on CloudWatch alarms are frequent AWS DevOps exam topics.
