Nowadays, Information technologies have an indisputable role in human life. In recent years, cloud computing technologies provide many opportunities for the users and is one of the technologies that keep popularity at the highest level. Briefly, cloud computing is a system that provides common data storage and usage for users. However, there are disadvantages as much as the advantages of cloud computing technology. The main disadvantage is security vulnerabilities. In this study, the behaviour of cloud computing system was analysed mathematically after the attack occurred and until the normal working order of the system. In this study, QoS analysis was carried by analysing response time and throughput by examine the effects of attacks on system performance. As a result of the propose analyses, the system's efficiency rate has decreased rapidly when the attacks are more frequent. For this reason, it has been determined that we need to develop preventive and fault tolerance systems.
