The rapid development of computer technology and applications has caused the increasing need for computer use in an organization. The performance of personal computers has increased rapidly, but they cannot be utilized properly. Therefore, personal computers can be used together to perform parallel processing, in order to shorten data processing time. This paper discusses Private cloud, which could be utilized as an alternative solution to provide cloud services to organizations that are in the

... same network. The service provided was Infrastructure as a Service (IaaS), where users can request certain types of services and use certain operating systems. Most universities have many computers in the laboratory that have considerable resources for a superb processing potential if they optimized properly. Supported by high specification on each computer, the laboratory is suitable for private cloud implementation. The use of the OpenStack framework can produce sufficient performance to perform parallel data processing. The test results showed that the parallel processing performance worked as expected.
