A digital brain to engage 350M customers in real time
About Bharti Airtel Limited
Bharti Airtel Limited, also known as Airtel, is the largest mobile networking operator in India and the third largest in the world with services in South Asia and Africa. It offers services in banking as well as mobile telephony, fixed line, broadband, IPTV, and digital TV. Airtel has experienced massive growth, from four million users in India in 2004 to some 320 million users in 2020, and expanding to 600 million by the end of 2021.
Unify real-time, personalized, experiences for 350M customers
With 1.3B potential customers in India alone, competition is fierce to win and retain customers. Airtel’s goal is to create delight and a seamless experience for their customers spanning all Airtel’s services and channels — mobility, broadband internet, TV, and payments. But first, Airtel needed to leave behind their outsourced technology approach with IBM and develop an in-house common platform aimed at unifying their siloed business systems from the ground up.
Scale is a huge challenge for Airtel. They need to process over 100B records a day, growing to over 200B records daily by the end of next year. The solution — Customer 360 — needs to use a single repository to look at stored data and real time information, apply AI and machine learning, anticipate the customer’s next action or interest, and serve up customized, personalized experiences. It also needs to identify which users are key influencers in their social and work circles, and target those users with offers to help drive adoption of services.

Real-time competitive edge accomplished in months, not years
Aerospike gives Airtel the ability to gain a real‐time competitive edge over its competition. Not only did Aerospike provide a data solution that could handle its heavy, mixed workload technical requirements, the Aerospike team also worked closely with Airtel to bring its new solution to market in record time. The project, which Airtel would have normally expected to take years, was accomplished in 16 months.
Aerospike is currently used in multiple use cases at Airtel, including:
The common database layer that sits across Airtel’s entire technology stack, providing high transaction, high value, and ultra low latency.
The data store that processes 350M customer records in Customer 360 and extends to the bank and payments platform, providing high responsiveness, real time accessibility, and low latency, mixed workload transactions.
The data layer for TEAM, a deep, open API-based platform that provides developers the ability to develop solutions on top of Airtel platforms in real time.
