ARM64 Migration Overview

Hyperconnect has successfully migrated a significant portion of its workloads to ARM64 architecture using AWS Graviton processors. The transition started with a cost-saving exploration of Graviton2 instances, which offer approximately 20% lower prices and up to 40% better performance compared to Intel instances. The initial migration involved testing managed services like Elasticache and RDS, followed by a broader migration of Kubernetes-based microservices. A dual architecture strategy was implemented to allow coexistence of AMD64 and ARM64 applications during the transition.

Migration Strategy

• Preparation of ARM64 nodes in the Kubernetes cluster.
• Building multi-architecture Docker images for applications.
• Modification of CI/CD pipelines to support ARM64 builds.
• Gradual rollout through canary deployments.

Through these efforts, Hyperconnect achieved a significant reduction in EC2 instance costs, with ARM64 instances accounting for over 47% of their total usage by mid-2023.
