Case Study: Calm achieves faster, more stable cloud infrastructure with Toptal’s AWS EKS rebuild

Calm rebuilds infrastructure in 3 days with Toptal

The wellness app Calm faced a critical two-day outage in its self-managed Kubernetes environment, highlighting vulnerabilities due to limited in-house DevOps capacity. Each hour of downtime cost an estimated $40,000. To address this, Calm engaged Toptal for expert assistance.

Toptal’s solution was to rapidly rebuild the infrastructure on Amazon EKS within just three days, rather than repairing the failed system. This move to a managed control plane immediately stabilized operations. The results included improved reliability, faster server responses, and the avoidance of an estimated $1.92 million loss from the prior outage, providing Calm with a scalable and secure foundation.
