Performance and security issue on open source private cloud

Open Source Private Cloud Software is widely used in many organizations. Eucalyptus is one of the popular open source private cloud software for building private and hybrid clouds. The benefits of this open source software for private clouds are highly efficient scalability, organization agility, and increased trust and control for IT. These studies perform tests on performance of the services of websites by using performance test tools - LoadUI and Web Performance Load Tester with some security issues purposed. The six evaluation of the performance tests are 1) average response time 2) peak response time 3) error rate of data transmission 4) throughput 5) request service per second and 6) amount of concurrent user in the system. By comparing performances with dedicated server (not on cloud), the test results from these two programs show average response time of website on cloud server is less than website on dedicated server, peak response time of website on cloud server is less than website on dedicated server, error rate of data transmission is zero on both website on cloud server and dedicated server, throughput of website on cloud server is higher than website on dedicated server, request service per second of website on cloud server is higher than website on dedicated server and amount of concurrent user in the system of website on cloud server is higher than website on dedicated server.
