Desktop as a Service (DaaS) is a cloud-hosted VDI service, offered by providers like Amazon, Microsoft Azure, Google, VMware, and Citrix. With DaaS, organizations do not need to provision servers or manage VDI infrastructure—both hardware and the VDI control plane is fully managed by the service provider.
DaaS systems are subscription-based, usually billed on a per-user basis, with little or no initial investment. All infrastructure setup and maintenance is handled by the DaaS provider.
