Question

A company operates an application on Amazon Elastic Kubernetes Service (Amazon EKS) clusters in the company’s primary AWS Region and secondary Region. The company uses Auto Scaling groups to spread each EKS cluster’s worker nodes across multiple Availability Zones. Each EKS cluster also uses an Application Load Balancer (ALB) to distribute inbound traffic. The company plans to deploy a new stateless application to this infrastructure. The company requires a fault-tolerant, multi-Region solution. Which solution meets these requirements?

Accepted Answer

A. Deploy the new application to both EKS clusters. Create Amazon Route 53 records with health checks for both ALBs. Use a failover routing policy. Implement Kubernetes readiness and liveness probes.

Answer

Deploy the new application to the EKS cluster in the primary Region. Create Amazon Route 53 records with health checks for the primary Region ALUse a simple routing policy.

Answer

Deploy the new application to both EKS clusters. Create Amazon Route 53 records with a weighted routing policy that evenly splits traffic between both ALBs. Implement Kubernetes readiness and liveness probes.

Answer

Deploy the new application to the EKS cluster in the primary Region. Create Amazon Route 53 records with health checks for the primary Region ALB. Use a failover routing policy.
