Case Study: Learning-simulations leader (training large user groups) achieves scalable 50,000+ concurrent-user media streaming with QASource performance testing

Large User Group - Customer Case Study

Large User Group engaged QASource to validate the scalability of their e‑learning media‑streaming platform before a large training rollout. The customer required performance testing of multiple workflows with embedded videos, simulation of over 50,000 concurrent users, real‑time server monitoring, and automated test execution integrated with CI.

QASource distributed load across geographic locations, selected an optimal testing tool and cloud platform, integrated an APM, and automated tests via CI; in five weeks they completed a full test iteration and successfully simulated more than 50,000 concurrent users. QASource’s testing exposed high‑priority issues—slow transactions, request timeouts, third‑party failures, OutOfMemoryError, elevated app/database resource use, and suboptimal search queries—providing the Large User Group with actionable findings to improve scalability and reliability.
