Challenges with On-Premise Mobile Banking Platform

The bank's on-premise mobile banking platform is facing challenges related to oversized infrastructure leading to high maintenance costs, particularly regarding expanding capacity to handle user growth and usage peaks, maintaining multiple development/staging/UAT/preproduction/production environments, and database licensing fees. The existing infrastructure is proving costly and inflexible, hindering agility and innovation.

  • Implement a fully automated CI/CD pipeline for faster and more reliable software releases.
  • Eliminate database license costs by migrating to an open-source alternative (PostgreSQL).
  • Improve software development quality and reduce the risk of human error.
