I'm looking for advice on how to set up traffic distribution across multiple EKS clusters after experiencing an outage in the us-east-1 region. I'm planning to establish another cluster in us-east-2, but I'm unsure about the best practices for distributing traffic between these two regions. All my Kubernetes resources are linked to a single region, and the traffic flows from the public internet. Any suggestions would be really appreciated!

You might want to consider Route 53's geo-routing feature, which could help with traffic distribution across regions. You can check out the detailed setup in the AWS documentation. It's a solid solution for managing regional traffic efficiently.
One effective approach is to use Amazon Route 53 for DNS management. You can set up your EKS clusters like this:
- For us-east-1, route traffic through a regional Application Load Balancer (ALB) connected to your EKS cluster.
- Do the same for us-east-2.
Then, configure a Route 53 record that points to both regional ALBs and apply a routing policy. Don’t forget to implement health checks in Route 53 to automatically reroute traffic if one cluster fails. Let me know if you need more guidance!
Have you thought about using CloudFront with two separate origins for your EKS clusters? It could provide additional benefits in terms of caching and distribution, though if you're mostly focused on backend services, maybe it isn't necessary. Just a thought!
It would be helpful to know more about your setup. In my case, we have one data center per region, and we utilize managed AWS services, which simplifies the distribution. We're using Akamai for traffic management, but Route 53 can handle similar tasks.
If your services are primarily based on Kubernetes, integrating external services could enhance your architecture.
