Case Study: Bharti Airtel achieves real-time customer personalization at scale with Aerospike

Bharti Airtel reduces TCO by 90% with Aerospike

Bharti Airtel, a leading telecom operator, faced the challenge of unifying real-time, personalized experiences for its 350 million customers. The company needed to process over 100 billion records daily, aggregate data from all customer channels, and increase engagement by predicting customer actions. To build its Customer 360 solution and leave behind a legacy outsourced system, Airtel turned to the Aerospike database.

Aerospike provided a high-performance data layer that consolidated Airtel's customer data into a single repository capable of handling 40,000 transactions per second with sub-millisecond latency. The solution enabled Airtel to process over 100 billion records daily and gain a holistic customer view. By implementing Aerospike, Airtel achieved a 90% reduction in total cost of ownership compared to its previous Oracle system and realized 99.999% reliability.
