We leverage AWS Global Accelerator to enhance application availability and performance across multiple AWS regions, primarily to support seamless traffic management for blue-green deployments and improve fault tolerance. Our environment consists of applications deployed across multiple regions, with each region hosting distinct versions for testing and updates.
Using AWS Global Accelerator, we route traffic to different regional endpoints to test new application versions before fully transitioning. This enables smooth blue-green deployments and rolling updates without downtime. Additionally, the service's static anycast IP addresses and intelligent traffic routing have improved fault tolerance by automatically redirecting traffic to healthy endpoints during regional failures. We conducted load testing to evaluate performance, measuring metrics such as requests per second and latency, which demonstrated significant improvements compared to traditional load balancing configurations.
