abstract = {The CLARA experiment at the STFC, Daresbury laboratory has just completed its first successful exploitation period. The CLARA controls system is being rapidly deployed as CLARA enters its next development phase and our current infrastructure is becoming hard to maintain. Virtualization of the server infrastructure will allow the rapid deployment, recovery and testing of systems infrastructure. This talk will review our experience of migrating several key services and IOCs to a virtualized environment. KVM and LXD have been evaluated against our current system and Ansible has been used to automate many tasks that were normally done by hand. The Archiver Appliance is being exploited beyond its original deployment and is a critical component of several analysis tool-chains. Virtualization allows development, maintenance and deployment of the archiver without disrupting its users. Virtualization is also used to manage the CLARA Virtual Accelerator. The Virtual Accelerator can now run with many instances proving useful for scientists. Originally, it was limited to one instance per server.},
