Case Study: Leading Indian Bank achieves faster turnaround and lower overheads with Persistent Systems integration architecture

Indian private sector bank reduces overheads and improves turn around time with robust integration architecture

Persistent Systems helped a leading Indian bank serving more than 7 million customers modernize its enterprise integration landscape. The bank needed a blueprint for an end-to-end integration platform, API management to expose consumer APIs internally and externally, governed reference data management, and a path to migrate the platform to an alternative product stack.

Persistent Systems implemented a middleware architecture with operational intelligence, developed 1,400+ services, and integrated 30+ applications. Using MongoDB for a secure reference data vault with role-based access control, Persistent Systems also supported BAU operations with DevOps tooling, helping the bank improve productivity, reduce implementation costs, and speed turnaround time while strengthening regulatory compliance.
