System Stabilization

Eliminating disruption while migrating legacy to new


  • A leading financial institution experienced significant stability and performance issues with its money movement systems.
  • Outages related to unexpected growth in usage and application design issues led to missed SLAs and spikes in customer complaints.
  • Overly complex database design, substandard latency in cross data center replication and out-of-date processes created unexpected risks during outages that prevented automatic failover.

  • EEI’s team of domain and subject matter experts conducted an extensive analysis of all aspects of the department’s money movement systems, databases, replication strategy and future state plans.
  • EEI redesigned the system’s databases and modified data server configurations, buffer pools and partitioning which led to increased performance across the entire tech stack.
  • EEI developed several bespoke future state options for consideration and, working with senior management, advised in the decision-making process to lead the company to its most viable options.
  • EEI implemented a series of parallel projects building software while running training sessions so the firm could continue successful development themselves in the future.
