How IDFC FIRST Bank built a real-time customer data access engine with Aerospike

IDFC FIRST Bank, launched in 2018 with a digital-first approach, faced challenges in maintaining real-time data consistency across its expanding multi-channel ecosystem, which includes mobile apps, web applications, and partner interfaces. As the bank scaled, traditional relational databases proved inadequate for the high-concurrency, real-time demands of modern digital banking, leading to issues like inconsistent customer data and operational risks. To address these challenges, IDFC implemented Aerospike's NoSQL database as a unified, real-time customer state store, ensuring consistent and immediate data updates across all channels. This transition resulted in significant improvements in performance, with read and write speeds increasing by 75% to 90%, replication latency dropping by 66%, and overall system efficiency rising by 20%. The new architecture not only enhanced system reliability and resilience but also enabled IDFC to focus on innovation and expansion, providing customers with a seamless and trustworthy digital banking experience.
