Case Study: Doctolib achieves secure, high-scale healthcare messaging with Akka

Doctolib runs secure messaging for 1M+ healthcare providers with Akka

Doctolib, a European e-health leader, needed to build a modern, encrypted, and compliant messaging system for over a million healthcare providers to securely handle sensitive patient data. The challenge was to create a provably reliable system that met strict European regulations without the high operational cost and compliance surface area of conventional infrastructure like external caches and message queues.

Using the Akka Agentic AI Platform, Doctolib implemented a distributed messaging system with built-in sharding, clustering, and replication. This solution eliminated the need for external dependencies, allowing two engineers to build the system in just three months and run the entire backend. The results include handling 2,500 messages per second at peak, achieving 99.9999% availability, and ensuring full regulatory compliance, all while significantly reducing infrastructure and operational overhead for Doctolib.
