To modernize our Virtual Desktop Infrastructure (VDI) and reduce costs, we transitioned from VMware Horizon to an open-source solution powered by OpenStack and OpenUDS. OpenStack provides the virtualization backend for deploying and managing virtual machines, while OpenUDS acts as the connection broker, handling desktop delivery, user authentication, and session management. This architecture enables flexible, scalable, and cost-effective virtual desktops, leveraging components like Nova, Glance, Neutron, and Keystone. OpenUDS integrates seamlessly with OpenStack to dynamically provision desktops based on user demand. Our new VDI solution improves performance, eliminates licensing costs, and gives us full control over infrastructure, while maintaining a smooth user experience through web-based access and automation. This transformation demonstrates the viability of open-source VDI for enterprise environments.
