This session explores canary and blue-green deployment strategies in multi-cluster environments using AWS EKS, external-dns, Route 53, and KubeStellar. Drawing from the speaker's experiences, attendees will gain practical insights into managing clusters across different VPCs and regions.

Canary deployments gradually introduce new versions, ensuring stability, while blue-green deployments maintain two identical production environments for comprehensive testing. The presentation will highlight specific challenges faced during deployment on AWS EKS with ALB and offer solutions based on real-world experiences. Despite following AWS documentation, various hurdles were encountered due to gaps in EKS-specific knowledge, leading to unexpected results. This session will demonstrate how opensource projects like KubeStellar can facilitate successful canary and blue-green deployments, helping attendees avoid similar pitfalls.
