          Private Cloud - Creating highly virtualized pools of compute, storage, and network resources.

          Building a Private Cloud

          Cloud Computing Basics

          Cloud computing delivers IT as a service to end users through the use of the Internet and technology such as virtual machines to share software and hardware. With its focus on enabling users to dynamically request IT services, the cloud differs from traditional IT.

          It is currently grouped into three types of offerings:

          • Public Clouds: IT services shared by multiple organizations; managed by an external provider
          • Private Cloud: Pooled internal resources of a single organization, delivered on demand
          • Hybrid Cloud: An organization’s use of a mix of private and public cloud infrastructures

          The Case for Building a Private Cloud

          One of the most common reasons organizations initially consider cloud computing is to reduce TCO and minimize IT infrastructure investments. However, IT professionals quickly realize that the biggest benefit is IT agility. Using the cloud, they can deliver IT services more efficiently; simplify provisioning and deployment; and rapidly scale to meet the needs of the organization.

          Despite all the benefits of reduced costs and increased agility, many organizations harbor concerns tied to the privacy and security of their data. Leveraging a “private cloud” within the walls of an organization can address this concern. IT can build their own “cloud” infrastructure by creating highly virtualized pools of compute, storage, and network resources, and realize many of the same benefits of the public cloud, without the risk associated with relying on an external provider to ensure security.

          The Technologies of the Private Cloud

          The technologies creating the underpinnings of a private cloud begin with virtualization. For example, VMware builds on virtualization to deliver cloud infrastructure and management solutions, cloud application platform solutions and end-user computing solutions that significantly reduce IT complexity.
