We use VMware Cloud Foundation as the hypervisor and VMware Cloud Director as the multi-tenant management interface. 

Anything supported by VMware vSphere 8.  This typically includes Windows Server OS back to 2008 R2, and all Linux distributions. 

vGRID provide a fully managed service when selected and also offer self-service capabilities for end-users where required.  Backups can be local as well as off-site for added protection. 

We use HPE Synergy Gen 11 compute modules. 

Our performance tier uses HPE Alletra 9000 arrays, and our capacity tier uses HPE Alletra 5000 arrays.  

All vGRID IaaS customer environments are connected to the Internet via a dedicated Sophos XGS virtual firewall appliance.
