Private Cloud Computing Deployment Model

A private cloud is a cloud infrastructure operated/established solely for a single organization or specific group and limits access to just that group.A private cloud is a proprietary network or a data center that provides hosted services to a limited number of people/to an organization.
It consists of applications or virtual machines in a company’s own set of hosts.In this form, the cloud is deployed with in a corporate firewall and runs on IT infrastructure. It is deployed on a private network.When a service provider uses public cloud resources to create their private cloud, the result is called a virtual private cloud.This form provides more benefits to the corporate by capitalizing on the Data Security and Corporate Governance and thereby the administrators can have more control over the operating environment.
Undertaking a private cloud project requires a significant level and degree of engagement to understand the business environment, and to establish the cloud properly it is required  that the organization may have to re-evaluate decisions about existing resources.
The disadvantage of private cloud is that it is more expensive compared to the public cloud since the operating and bandwidth costs are to be maintained by the organization.But a big advantage of  this cloud is that it is more secure than the public cloud.If this type of cloud is established properly then, it can have a positive impact on business.
The benefits offered by Private Cloud is
  • Utility computing
  • More control over operating environment
  • Shared hardware costs
  • More secure than public cloud
  • Ability to recover from failure
  • Ability to scale up or down depending upon demand
