When Organizations uses private dedicated environments, i.e. organization is running an environment where the sole tenant is the company itself. The company is ultimately responsible for maintaining the hardware, software, and networking infrastructure. On premises servers are also referred to as private clouds, just that on premise servers runs in local intranet. Private clouds can be classified into following categories:
