Optimizing storage performance for Amazon EKS on AWS Outposts

This article provides guidance on optimizing storage performance for Amazon EKS running on AWS Outposts, covering hybrid cloud deployment options and storage solutions.

• EKS extended clusters keep control plane in AWS Region; local clusters host control plane on Outposts
• Amazon EBS provides high-performance local block storage with consistent latency and IOPS
• Amazon EFS enables shared file storage but requires service link connectivity to AWS Region
• Amazon S3 on Outposts delivers local object storage with S3 API compatibility
• Monitor CloudWatch metrics for IOPS, throughput, latency, and burst balance across storage types
• Implement AWS KMS encryption, TLS, and least-privilege IAM policies for security
• Optimize costs through right-sizing, lifecycle policies, and automated backups

Organizations can build resilient hybrid applications by selecting appropriate storage solutions based on performance, compliance, and data residency requirements.
