Case Study: Pharmacy OneSource achieves 600% faster message processing and $20M cost savings with GigaSpaces

Pharmacy OneSource - Customer Case Study

Pharmacy OneSource, a leading U.S. healthcare SaaS provider serving over 1,300 hospitals and 44,000 pharmacy professionals, needed to deliver real-time, data-driven analytics to improve care quality, cost and compliance. Their legacy architecture was limited by disk speed and poor scalability, causing message backlogs, processing delays and timeouts; the company required doubled capacity, linear/dynamic scaling to handle millions of messages daily, sub-10-second response times, and a cloud-ready path forward.

Pharmacy OneSource implemented GigaSpaces XAP’s in-memory data grid and dynamic scaling, enabling cloud readiness and fast time-to-market. In under five months they migrated initial applications and achieved a 600% increase in message throughput (25 → 130 msg/sec), a 15% reduction in legacy load in phase one, 4x higher tenancy per instance, support for over 4 million daily messages across 200,000 patients with 9,000 real-time rules, and an estimated $20M in five-year infrastructure savings—improving performance and patient outcomes.
