AWS Networking Solution for EKS Clusters without Direct Connectivity

Did you know that even when you have two separate EKS clusters in different VPCs with no direct network connectivity, there's still a way to enable secure communication between them? In this latest DevOps tip, we explore how to achieve this using AWS PrivateLink, NLB, and VPC Endpoints. By creating a Network Load Balancer (NLB) for the microservice in one cluster, registering it as a VPC Endpoint Service, modifying the microservice to access via the NLB, and setting up an Interface VPC Endpoint in the other cluster, you can enable private communication without exposing services to the internet or requiring direct network connectivity between VPCs. This solution is particularly useful for organizations with multiple EKS clusters that require secure communication without compromising security.
