Private clouds are ones that are built specifically for a single company. They allow a company to run applications on the cloud while also addressing data security and control issues that are common in public cloud environments.
The data is safeguarded in a private cloud, often known as an internal cloud or enterprise cloud, which resides on the organization’s Intranet or hosted data centre.
Based on the access to the cloud, it is classified into the following groups:
Public Cloud: It’s a type of external cloud which is made available for the use of public and is essentially owned and provided by the external organizations. e.g. Amazon Web Services, Microsoft Azure and so on.
Private Cloud: Here infrastructure or services can be located on-premise or off-premise and is operational solely for the use of a single organization which would be the owner of the cloud. All cloud configurations are directly influenced by the owner. It can be managed by the organization itself or can also be outsourced to any third party. In case of private cloud the security of organization’s intellectual property is confirmed on the expense of huge initial investment in building the cloud and also brings in additional maintenance and training costs.
