Executive Summary

ANALYST: COI RESEARCH

The bank implemented a distributed, active-active data layer using DataStax (Apache Cassandra) to offload read-heavy traffic from legacy mainframes and ensure zero downtime.

rate_review Analyst Verdict

"A critical architectural pattern for incumbents. Placing a high-speed data layer in front of the mainframe protects the legacy core from digital traffic spikes while ensuring 100% availability."

warning The Challenge

As digital banking traffic surged, the bank's legacy mainframe systems struggled to handle the volume of read requests (e.g., balance checks, transaction history). This dependency created a risk of system outages during peak times and drove up MIPS (Millions of Instructions Per Second) costs, which are directly tied to mainframe utilization.

psychology The Solution

The institution deployed a distributed NoSQL database layer (DataStax/Cassandra) acting as an 'Operational Data Store'. This layer sits between the digital channels and the mainframe, handling high-volume read traffic with active-active replication across multiple data centers. It ensures that even if one site fails, digital banking remains available.
