Private Cloud Model

Private Cloud is also termed as 'Internal Cloud', which allows the accessibility of systems and services within a specific boundary or organization. The cloud platform is implemented in a cloud-based secure environment guarded by advanced firewalls under the surveillance of the IT department that belongs to a particular organization. Private clouds permit only authorized users, providing the organizations greater control over data and its security. Business organizations that have dynamic, critical, secured, management demand-based requirements should adopt Private Cloud.

The advantages of using a private cloud are:

1. Highly private and secured: Private cloud resource sharing is highly secured.
2. Control Oriented: Private clouds provide more control over their resources than public clouds as it can be accessed within the organization's boundary.

The Private cloud has the following disadvantages:

1. Poor scalability: Private type of clouds is scaled within internal limited hosted resources.
2. Costly: It provides secured and more features, so it's more expensive than a public cloud.
3. Pricing: is inflexible; i.e., purchasing new hardware for up-gradation is more costly.
4. Restriction: It can be accessed locally within an organization and is difficult to expose globally.
