Horizon 7 Sizing and Consumption Model : 7.2 Assessment
   
7.2 Assessment
Sizing Horizon 7 for an enterprise deployment requires a full assessment of the desktop estate, uses-cases including desktop configuration, and application workloads. This is not practical for many service providers, therefore resource blocks are provided to each tenant, and the role of Tenant Desktop Administrators will consume the capacity allocated to them for desktops and applications.
It is essential that service providers can scale tenant resources blocks on-demand, which is why SDDC components such as vSAN and NSX provide an excellent platform for the hosted digital workspace.
Note This does not mean that an assessment is not required. Architectural guidelines including a desktop assessment strategy still applies for Tenant Administrators. This may optionally be offered as a service by the provider.
To facilitate the hosted model, service providers will provide resource infrastructure blueprints as described in Section 7.3, Infrastructure Blueprints.
