Performance evolution of higher reliability task in cloud computing

Cloud computing is a computing paradigm which provide IT services not as a product but as a services, that could be found at everywhere at any time with easy access. Users can access these services by software's like web browser and mobile app using network (Internet). Utility service is an illusion of availability of as much resources (e.g., CPU, memory, and I/O) as demanded by the user. To reduce the above problem, nowadays data centers are moving from traditional data centers to cloud centers. However implementing cloud based data centers requires a great deal of flexibility, availability and reliability. Virtualization technology can provide these kinds of services. In a cloud environment higher reliability required when any problem with a single piece of hardware may spread across multiple systems, since multiple systems are deployed as guests of VM on a common piece of hardware. In this survey, we are studying the use of Cloud Infrastructure Management Software (CIMS) is a solution to be combined with ServerView Resource Orchestrator (ROR), in the virtual environment, a guest virtual machine (VM) in operation can be transferred to another host without interrupting the operation.
