Private Cloud Model
Private Cloud allows systems and services to be accessible within an organization. The Private Cloud is operated only within a single organization. However, it may be managed internally by the organization itself or by third-party. The private cloud model is shown in the diagram below.
There are many benefits of deploying cloud as private cloud model. The following diagram shows some of those benefits:
High Security and Privacy
Private cloud operations are not available to general public and resources are shared from distinct pool of resources. Therefore, it ensures high security and privacy.
The private cloud has more control on its resources and hardware than public cloud because it is accessed only within an organization.
Cost and Energy Efficiency
The private cloud resources are not as cost effective as resources in public clouds but they offer more efficiency than public cloud resources.
Here are the disadvantages of using private cloud model:
Restricted Area of Operation
The private cloud is only accessible locally and is very difficult to deploy globally.
Purchasing new hardware in order to fulfill the demand is a costly transaction.
The private cloud can be scaled only within capacity of internal hosted resources.
In order to maintain cloud deployment, organization requires skilled expertise.
