<b>An Investigation of Fault Tolerance Techniques in Cloud Computing</b> Cloud computing which is created on Internet has the most powerful architecture of computation that provides users with the capabilities of information technology as a service and allows them to have access to these services without having specialized information or controlling the infrastructure. Fault tolerance has. The main advantages of using fault tolerance that has all the necessary techniques to keep active power and reliability in cloud computing include failure recovery, lower costs, and improved performance criteria. In this paper, we will investigation of the different techniques that are used for fault tolerance on cloud computing. cloud computing, fault tolerance 1455-1457 Issue-5 Volume-3 Ya Min | Khin Myat Nwe Win | Aye Mya Sandar
