Case Study: $60B Global Telecom Provider achieves 40x capacity, 13x throughput and 90% cost savings with Software AG's BigMemory Max

$60 billion telecommunications firm uses BigMemory to serve hundreds of millions of worldwide customers

A $60 billion global telecommunications provider launched a pay-as-you-go global Wi‑Fi service that vastly outpaced expectations—reaching the five-year user forecast of 5 million in six months—and needed to scale to about 200 million users. Its existing Oracle RAC setup maxed out around 150 transactions per second and a vendor quote of $5 million to expand made the current approach prohibitively slow and expensive.

The company chose Terracotta BigMemory Max for enterprise-grade in-memory performance, high availability and fast restart. The deployment delivered a 40× capacity increase (5M to 200M users), a 13× throughput improvement (≈150 to >2,000 TPS) and roughly 90% cost savings versus the Oracle expansion; applications kept running at peak performance even when the database of record was down, and the provider is rolling BigMemory out to other billing and account systems.
