Backed by Successful Migration Stories

“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.”

Customer Beeks Group   

“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.”

Customer Encore Technologies  

“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.”

Customer Dustin  

“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.”
