Abstract: In Present days, one of the most appealing technologies is cloud computing in the current time. Now a day, different organizations are offering various cloud services concerning their platforms. These organizations are profitable in cost-efficiency to the end-users in various factors that include process, storage, and applications instance. Most of the end-users choose the services from the cloud service provider, whereas some medium-scale organizations are also depending on the service providers even though they have enough resources. This causes the problem due to a lack of knowledge on design and deployment issues. In this paper, we proposed a private cloud that offers cloud services with limited resources so that small and medium scale organizations can be benefited. In this work, we proposed a novel three tier architecture that contains Domain Controller (DC), Virtual Machine Manager (VMM), and Member Servers (MSs) at a different level of functioning and also have their responsibilities. In this Novel three tier architecture was designed in a hierarchal fashion in which the upper layer accesses the lower layer users. The top layer, which deals with the domain controller whose responsibility, is to control the domain-specific issues like adding the member in the network, granting permissions, creating network groups, etc. The middle layer has various administrative users like Virtual Machine Manager (VMM), Storage Area Network (SAN), Disaster Recovery (D/R), and Operational Manager (SCOM), which deals with their responsibilities in cloud services. In the bottom layer, the physical servers exist and are configured by DC and get access by the middle layer users. This architecture was tested with various applications with different instances concerning storage and process utilities.
