A Survey Paper on Fault Tolerance in Cloud Computing Environment

The capital cost of purchasing hardware, software and setting up and maintaining on-site data centers—including the server racks, round-the-clock electricity for power and cooling, and the IT professionals for managing the infrastructure—is eliminated by using cloud computing. Cloud computing allows IT to respond to business needs faster. If an application needs more resources or capacity, It can be rapidly and simply modified in the cloud. Another essential aspect of cloud computing is fault tolerance, which measures how well a system can continue to function in the face of mistakes or failures. This survey will help acknowledge the main fault tolerance issues and the loopholes in the traditional fault tolerance techniques that still need attention. This survey gives us insight into several methods that can be used to cater the challenges regarding fault tolerance.
