“One of the primary benefits was the up to 200% increase in virtual machine efficiency, meaning we could deploy more VMs per server, translating to a substantial cost-saving for both Beeks and our clients. We were surprised by how resource-intensive the VMware vSphere system had become, requiring more overhead to manage. OpenNebula, with its streamlined architecture, provided a more efficient alternative, allowing us to optimize resource usage.”
“With 10GB connections and shared ISCSI and NFS storage, migrations of basic VMs (90% of Windows and Linux VMs) typically complete in 15-60 minutes, while larger databases, such as 1.5TB Linux instance, take about 8 hours. All migrations (from VMware to OpenNebula) have been successfully executed with a limit of three simultaneous VMs.”
“With the Open API structure we can adjust and adopt tools and services on top of the platform that gives us operational benefits, both from a technical and economical point of view.”
“Qt is currently running over 4 million virtual machines per year on OpenNebula. After more than three years using OpenNebula in production, we can confirm that it is a great tool for doing the simple task of spawning millions of virtual machines per year.”
