Case Study: Viettel achieves sub-millisecond, 60,000 TPS online charging at 40% lower TCO with Aerospike

Viettel cuts TCO by 40% and scales to 400M users with Aerospike

Viettel, Vietnam's largest telecommunications provider, faced the challenge of modernizing its online charging system to combat customer churn and support rapid growth across diverse services and underserved regions. Their legacy system could not handle the demand for personalized, flexible services or scale to support millions of users and future innovations in 5G and IoT. To address this, Viettel selected Aerospike to power its new platform.

By implementing Aerospike's database, Viettel created a containerized, high-performance charging solution. This new system achieved sub-millisecond latency and over 60,000 transactions per second, enabling real-time personalization for customers. The results included a 40% reduction in total cost of ownership, five-nines availability, and the ability to scale from 170 million to 400 million users, earning Viettel global recognition for its digital innovation.
