Case Study: Pyro achieves carrier-grade, high-throughput roaming for 7 million subscribers with MySQL Cluster

MySQL & Pyro Score at the 2010 FIFA World Cup

Pyro Group, a global communications technology provider, deployed its InRoam Service Delivery Platform to enable seamless, low-cost international roaming for hundreds of thousands of fans at the 2010 FIFA World Cup. As InRoam gained adoption, Pyro faced a business and technical challenge: escape Microsoft stack lock‑in and licensing limits while meeting carriers’ demands for extreme performance, scalability and high availability during peak roaming events for customers like Cell C.

Pyro ported InRoam to Linux and chose MySQL Cluster 7.1 to deliver carrier‑grade availability, low latency and linear scalability on commodity blades. The MySQL Cluster–backed SDP was sized to support 7 million roaming subscribers per day (≈1,000 reads / 500 writes per second on up to 1 TB), reduced TCO by eliminating shared storage, and sped deployment (Cell C went live in one week versus the typical four), enabling reliable, high‑throughput roaming services.
