Fault Tolerance in Cloud Computing: A Survey

Using cloud computing services has many advantages, such as improving efficiency, reducing costs, compatibility with multiple formats, unlimited storage capacity, and easy access to services anytime and anywhere. It should be mentioned that the fault tolerance is the main restriction of all varieties of cloud computing services. Cloud service providers need to effectively handle performance-related reliability, availability, and throughput issues to maximize the potential of using cloud computing services.This paper provides a comprehensive overview of the issues related to fault tolerance in cloud computing. It focuses on important advanced technologies, and methods. Its purpose is to provide insight into traditional fault-tolerant approaches and the challenges that still need to be overcome. This investigation enumerates several promising methods that can be used for efficient solutions.
