Case Study: Fortune 300 Global Financial Group achieves 99.995% SLA compliance and millions in savings with Software AG BigMemory

Global Financial Group Earns Millions in Credit Card Profit

A Fortune 300 global financial group that processes thousands of credit-card transactions per second was missing its one-second SLA about 0.3% of the time, leading to blacklisted cards being accepted and an estimated $10 million in annual losses. The problem stemmed from a seven-million-entry blacklist kept on a disk-bound Oracle database and unpredictable Java garbage-collection pauses that caused extended, guesswork-driven outages.

The company deployed Terracotta BigMemory to move the blacklist into in-memory storage with persistent, fast-restartable architecture and WAN replication across global data centers, eliminating GC pauses and costly Java tuning. As a result it now meets the SLA more than 99.995% of the time, protects roughly 10GB of high-value blacklist data in memory, saved millions by flagging blacklisted cards faster, and plans to extend BigMemory to power fraud detection.
