Private Cloud

A Private Cloud is owned and operated by the organization that uses the resources from that cloud. They create a cloud environment in their own data centre and provide self-service access to compute resources to users within their organization. The organization remains the owner, entirely responsible for the operation of the services they provide.

Private Cloud type have following characteristics

Ownership - The owner and user of the cloud services are the same.

Hardware - The owner is entirely responsible for the purchase, maintenance, and management of the cloud hardware.

Users - A Private Cloud operates only within one organization and cloud computing resources are used exclusively by a single business or organization.

Connectivity - A connection to a Private Cloud is typically made over a private network that is highly secure.

Public access - Does not provide access to the public.

Skills - Requires deep technical knowledge to set up, manage, and maintain.

A use case scenario for a Private Cloud would be when an organization has data that cannot be put in the public cloud, perhaps for legal reasons. For example, they may have medical data that cannot be exposed publicly.

Another scenario may be where government policy requires specific data to be kept in-country or privately.

A Private Cloud can provide cloud functionality to external customers as well, or to specific internal departments such as Accounting or Human Resources.

Private Cloud Disadvantages:

Upfront CapEx - Hardware must be purchased for start-up and maintenance.

Agility - Private Clouds are not as agile as public clouds, because you need to purchase and set up all the underlying infrastructure before they can be leveraged.

Maintenance - Organizations have the responsibility for hardware maintenance and updates.

Skills - Private Clouds require in-house IT skills and expertise that may be hard to get or be costly.
