Desktop-as-a- Service providers can deliver virtualized desktop services through a multitude of Service use cases public or private cloud infrastructure business models, depending on the market
opportunity that they want to address. The most common use cases include:
• Enterprise desktop service is the simplest virtualized desktop business model.
In this case, the IT department is the service provider and the consumers are the employees within the company.
• Multi-departmental enterprise desktop services provide desktop services to
multiple cost-centers within the enterprise. In this use case, the service
provider is the enterprise's IT department but the services are billed to individual cost centers within the organization.
• Hosted virtual desktop infrastructure services are similar to enterprise services
except the infrastructure is owned, installed, and maintained by a third-party
service provider. The service provider and the enterprise negotiate a per- desktop or usage-based compensation structure.
• Multi-tenant hosted virtual desktop infrastructure is a complex use case where
a single service provider delivers desktop services to multiple enterprise
customers. This model requires a high level of security to ensure that each customer's desktop infrastructure is isolated and protected from access by other tenants or outside parties.
