is a cloud computing platform that is implemented within the corporate firewall, under the control of the IT department.
Private cloud infrastructure is a dedicated infrastructure provided to one single organization or client.
A private cloud is designed to offer the same features and benefits of public cloud systems, but does not have a number of weaknesses to the cloud computing model including control over enterprise and customer data, worries about security, and issues connected to regulatory compliance.
Private Cloud is a much more secure platform.A private cloud implementation aims to avoid many of the objections regarding cloud computing security. Because a private cloud setup is implemented safely within the corporate firewall, a private cloud provides more control over the company's data, and it ensures security, albeit with greater potential risk for data loss due to natural disaster.
PRIVATE CLOUD ADVANTAGES
Controls: Better controls for data, users and information assets.
Security: The cloud belongs to a single client. Hence, the infrastructure and systems can be configured to provide high levels of security.
Superior Performance: Normally private clouds are deployed inside the firewall of the organization’s intranet which ensures efficiency and good network performance.
Easy Customization: The hardware and other resources can be customized easily by the company.
Compliance: Compliance is achieved easily in private clouds.
PRIVATE CLOUD DISADVANTAGES
Cost: Costs are substantial in the case of building an on-premise private cloud. The running cost would include personnel cost and periodic hardware upgrade costs. In the case of outsourced private cloud, operating cost will include per resource usage and subject to change at the discretion of the service provider.
Under-utilization: In some instances the resources subscribed can be under-utilized. Hence, optimizing the utilization of all resources is a challenge.
Capacity ceiling: Due to physical hardware limitations with the service provider, there could be a capacity ceiling to handle only certain amount of servers or storage.
Vendor lock-in: This can be a major impediment in private cloud adoption especially when the hardware and infrastructure is outsourced. This is a service delivery technique where the client company is forced to continue with the same service provider, thus preventing the client to migrate to another vendor.
