Private Cloud

Private cloud deployment model is established to deliver services for a single organization. And it is a cloud infrastructure that is established for exclusive use by a single organization and comprising multiple consumers. And private cloud may be possessed, managed, maintained and operated by the organization, a third party or some combination of the two. Furthermore, it can only be accessed by members of the single organization established the private cloud. And it is a type of cloud computing deployment model that delivers similar advantages to public clouds such multitenancy, scalability and on-demand self-service. Besides, it adopts proprietary architecture to provide services to its constituents. However, unlike public cloud, which delivers services to multiple organizations, private cloud is dedicated to the needs and goals of a single organization.

Unlike public cloud which is multitenant environment, private cloud is a single tenant architecture and does not share resources with other users and organizations. Moreover, the resources of the private cloud can be managed and hosted in the organization’s on-premise datacenter or separate colocation infrastructures. Private clouds are usually established when public cloud architectures are deemed inappropriate for the business requirements of the organization. And It is a deployment model of cloud computing where the infrastructure is fully dedicated to a single user organization.

The benefits of private cloud architecture include the following:

• Enhanced cloud security
• Predictable and robust performance
• Long term cost savings
• Compliance requirements
• Complete control over resources
• Managed cost
• Improved efficiency
• Customization
• Hybrid integration
• Architectural freedom
• More flexibility
• Increased scalability
• Secure cloud based datacenter

There are four types of private cloud deployment architectures commonly used in cloud computing environments, which are discussed as follows:

• Virtual Private Cloud (VPC): a VCP is a type of private cloud deployment model that provides the benefits of private cloud with the help of public cloud resources.
• Hosted Private Cloud: This is a private cloud deployment architecture, an organization deploys their cloud servers in the datacenters of the private cloud vendors. Besides, the vendor is responsible to manage the security of the organization hosting its services.
• Managed Private Cloud: A type of private cloud deployment model in which the cloud infrastructure is dedicated to a single tenant architecture. And it is managed by a third-party private cloud vendor.
• On-premise Private Cloud: allows organizations to host a cloud environment internally within the organization’s data center.
