Introducing the Amazon EKS Hybrid Nodes gateway for hybrid Kubernetes networking

Amazon Web Services has launched the Amazon EKS Hybrid Nodes gateway, a new networking feature designed to simplify connectivity between cloud-based Amazon EKS clusters and on-premises Kubernetes workloads. The gateway automates the complex networking requirements that typically arise in hybrid Kubernetes deployments, eliminating the need for manual routing configuration changes or extensive coordination with network infrastructure teams when running workloads across both environments. The new gateway addresses several critical networking challenges by automatically enabling communication between the Kubernetes control plane and webhooks, facilitating pod-to-pod traffic across cloud and on-premises infrastructure, and providing connectivity for AWS services including Application Load Balancers, Network Load Balancers, and Amazon Managed Service for Prometheus. Organizations can deploy the gateway to Amazon EC2 instances using Helm, and the system automatically maintains VPC route tables as workloads scale up or down. The Amazon EKS Hybrid Nodes gateway is now available at no additional charge in all AWS regions where Amazon EKS Hybrid Nodes is supported, excluding China regions. Customers only pay for the underlying AWS infrastructure costs, including EC2 instance charges and data transfer fees. AWS has also made the gateway's codebase available as open source, allowing organizations to inspect and potentially contribute to the project.
