Hosted Dedicated Private Cloud (DPC)

Hosted Dedicated Private Cloud (DPC)

Dedicated physical resources focused on one enterprise/extended enterprise. DPC services are provided on dedicated/isolated physical resources to a single enterprise or an extended enterprise. DPC services often use server, network, or storage virtualization within dedicated physical resources, based on choices made by both provider and user firm. DPC is further segmented into information services outsourcing (ISO) and hosting infrastructure services which relate to business models of the provider.

On-demand Dedicated Cloud
(VPC - Virtual Private Cloud)

On-demand Dedicated Cloud
(VPC - Virtual Private Cloud)

Hosted hardware environment (pooled resources) with a virtualization layer, allowing business customers to directly create, provision, and manage multiple dedicated virtual server and storage instances within a shared physical infrastructure. VPC services are best thought of as "private cloud built on public cloud" as they are premium versions of public cloud infrastructure (server, storage, or system management) services, offered from the same shared infrastructure as public cloud IaaS. This market is segmented further into storage VPC and server VPC depending on the services provided in the cloud.

Public Cloud

Public Cloud

Cloud software services are services built with a utility computing environment in which unrelated customers share a common application and/or infrastructure that is managed by an ISV or a third-party service provider. In public cloud, the software code (or intellectual property) of the service is typically owned by the SaaS ISV.

A public cloud has the following key attributes:

  • A shared, standard service built for multi-tenancy capable of supporting multiple clients or enterprises
  • Solution packaged - a "turnkey" offering
  • Self-service provisioning and management
  • Elastic resource scaling, dynamic, rapid, and fine grained
  • Elastic, use-based pricing, supported by service metering
  • Ubiquitous (authorized) network access, typically accessible via the Internet
  • Standard UI technologies, browsers, RIA clients, and underlying technologies
  • Published service interface/API, web services, other common Internet APIs
