Question

A software-as-a-service (SaaS) company uses an Amazon Elastic Container Service (Amazon ECS) cluster behind an Application Load Balancer (ALB) to deliver real-time analytics services to clients. The company uses AWS CodePipeline and AWS CodeDeploy to establish a blue/green deployment process for the solution. The company requires the deployment process to automatically shift traffic in equal increments across a specified total deployment time, with no manual intervention. The deployment process must ensure zero downtime and seamless updates. Which solution meets these requirements?

Accepted Answer

D. Set up a deployment configuration in CodeDeploy. Configure weighted routing on the ALB during deployment.

Answer

Set the TrafficRoutingConfig parameter to TimeBasedLinear in the appspec.yaml file of the CodeDeploy application that the company uses to deploy the ECS services. Set values for the linearPercentage parameter and the linearInterval parameter.

Answer

Update the TrafficRoutingConfig parameter of the appspec.yaml file of the CodeDeploy application that the company uses to deploy the ECS services to the AllAtOnce type.

Answer

Create a deployment group configuration. Set the TrafficRoutingConfig parameter to the TimeBasedCanary type. Configure listener rules on the ALB to forward traffic to the target groups based on specified weights.
