Implementing granular failover in multi-Region Amazon EKS

This article discusses a solution for implementing granular failover in multi-Region Amazon EKS (Elastic Kubernetes Service) environments, addressing challenges in multi-tenant infrastructure.

• Traditional multi-Region architectures force uniform failover policies across all applications
• The proposed solution uses application-specific Route 53 health checks to enable selective failover
• Key benefits include:
  • Enhanced monitoring at the application level
  • Intelligent failover management
  • Maintaining multi-tenant cost benefits
• The solution allows organizations to:
  • Achieve application-specific resilience
  • Meet diverse availability requirements
  • Avoid unnecessary cross-Region routing

The article provides a detailed walkthrough of implementing this solution, including creating EKS clusters, configuring Route 53 health checks, and setting up alias records to enable granular failover.
