Implement centralized observability for multi-account Amazon EKS

This article explains how to implement centralized observability for multi-account Amazon EKS clusters using a hub-and-spoke architecture combining three complementary approaches.

• Enable Amazon EKS Dashboard for organization-wide cluster health and upgrade visibility
• Configure CloudWatch cross-account observability to replicate metrics, logs, and traces across accounts within regions
• Create cross-account cross-Region dashboards using IAM role assumption for multi-region visibility
• Hub-and-spoke pattern centralizes monitoring while maintaining account isolation and security boundaries
• No additional charges for cross-account observability; dashboards cost $3/month each
• Reduces incident response time by eliminating console switching and manual metric correlation
• Supports up to 100,000 source accounts per monitoring account
• Use CloudFormation StackSets to automate link creation across multiple accounts at scale

This solution unifies fragmented multi-account EKS monitoring into a single pane of glass without modifying existing infrastructure, enabling faster incident response and proactive capacity planning.
