Case Study: The Qt Company runs 4 million VMs per year with OpenNebula Systems

OpenNebula for C/I – Running over 4 million VMs per year

The Qt Company, a global software firm developing the Qt framework, faced significant performance challenges with its continuous integration (CI) system. Their legacy infrastructure, which utilized VMware vSphere and Jenkins, resulted in severe bottlenecks; autotests took 30 times longer to run, and their centralized storage repeatedly failed. They needed a robust, cost-effective solution designed specifically for creating virtual machines (VMs) on demand, leading them to seek a new vendor, OpenNebula Systems.

OpenNebula provided a lightweight, open-source cloud platform that replaced the previous system. This solution allowed The Qt Company to deeply troubleshoot issues and fix drivers for optimal performance. The result was a highly efficient CI environment that now runs over 4 million VMs per year without hiccups, enabling rapid verification of developer commits across multiple environments and providing substantial cost savings compared to their previous proprietary licenses.
