Case Study: Superhuman reduces AWS cross-AZ traffic by 50% with Buoyant Linkerd

Superhuman reduces AWS cross-AZ traffic by 50% with Buoyant

Superhuman, an AI productivity platform, faced significant engineering complexity and operational burden from managing a vast multi-cloud, multi-region infrastructure supporting over 40 million users. Their challenge was to secure service-to-service communication, reduce reliance on costly external load balancers, and simplify networking across hundreds of AWS accounts as they migrated to Kubernetes.

By implementing Buoyant's Linkerd service mesh with its High-Availability Load Balancing (HAZL) feature, Superhuman achieved mandatory mTLS encryption and simplified cross-cluster communication. The solution delivered a measurable 50% reduction in AWS cross-AZ traffic, drastically cut the number of load balancers required, and resulted in significant overall cost savings for Superhuman.
