Case Study: Nokia achieves sub-millisecond, real-time billing at scale with Aerospike

Improved Customer Experience through Enhanced Real-Time Billing and Charging Systems

Nokia Networks, which builds applications for telcos and communications service providers, faced declining customer satisfaction and mounting competitive pressure because its legacy billing and charging systems could not keep up with streaming and edge-generated data. The old platform produced questionable billing accuracy, was hard to integrate and change quickly, and could not scale economically to handle terabytes of data and tens of thousands of transactions per second.

Nokia rebuilt its real-time billing and charging stack on Aerospike’s flash‑optimized NoSQL platform, enabling sub-millisecond latency, high throughput, 5‑9s availability and cross‑data‑center replication. The new solution supports per-account routing, traffic shaping, real-time subscriber notifications, differentiated data plans and self‑service provisioning, delivering dramatic TCO savings versus in‑memory alternatives while increasing service uptake, enabling timely personalized offers and reducing churn.
