A company is designing a service that mandates encryption in transit, ensuring traffic remains encrypted from the client to the backend. The service will utilize the gRPC protocol over TCP port 443 and must support thousands of concurrent connections. The backend will be deployed on an Amazon EKS cluster with Kubernetes Cluster Autoscaler and Horizontal Pod Autoscaler enabled. Mutual TLS is required for two-way authentication between the client and the backend.
Which solution fulfills these requirements?
A
Install the AWS Load Balancer Controller for Kubernetes. Using that controller, configure a Network Load Balancer with a TCP listener on port 443 to forward traffic to the IP addresses of the backend service Pods.
B
Install the AWS Load Balancer Controller for Kubernetes. Using that controller, configure an Application Load Balancer with an HTTPS listener on port 443 to forward traffic to the IP addresses of the backend service Pods.
C
Create a target group. Add the EKS managed node group's Auto Scaling group as a target Create an Application Load Balancer with an HTTPS listener on port 443 to forward traffic to the target group.
D
Create a target group. Add the EKS managed node group’s Auto Scaling group as a target. Create a Network Load Balancer with a TLS listener on port 443 to forward traffic to the target group.
