Amazon EKS Hybrid Nodes allow running generative AI inference workloads across cloud and on-premises environments, offering consistent management and reduced operational complexity.
EKS Hybrid Nodes support various AI/ML use cases like real-time edge inference, on-premises data residency, and running inference workloads closer to source data.
Proof of concept involved deploying a single EKS cluster for AI inference on-premises with EKS Hybrid Nodes and in the AWS Cloud with Amazon EKS Auto Mode.
Prerequisites include setting up Amazon VPC, AWS Site-to-Site VPN connection, on-premises nodes with NVIDIA drivers, and tools like Helm, kubectl, eksctl, and AWS CLI.
Steps include creating an EKS cluster with EKS Hybrid Nodes and Auto Mode enabled, preparing hybrid nodes, installing NVIDIA device plugin for Kubernetes, and deploying NVIDIA NIM for inference.
Validating nodes connectivity, deploying GPU-specific solutions for Auto Mode, such as g6 instance family, and testing NIM for inference were part of the deployment process.
Cleanup steps were outlined to avoid long-term costs, and the post emphasized how EKS Hybrid Nodes simplify AI workload management by unifying Kubernetes footprint.
For more detailed guidance, users are directed to the EKS Hybrid Nodes user guide and re:Invent 2024 session (KUB205) explaining hybrid nodes functionality, features, and best practices.
