Cloud computing is a standard for conveying, arranging and getting access to substantial scale disseminated computing applications over the system. In cloud computing, fault tolerance is a drastic issue and one of the metric which consider being most critical because the resource failure affects work execution, response time, throughput and execution of framework and system. To overcome this fault tolerance the load is divided among free machines for the fulfilment of the job. Reliability and energy efficiency are also the two key difficulties in cloud computing systems (CCS) that need to be considered while handling with cloud. The current review articles are either centered on the energy efficiency and reliability systems techniques in cloud computing. This paper also reveals the key issues of reliability and energy efficiency and their exchange off in cloud computing. We also talk about the arrangements on resource allocation, adaptation to non-critical failure techniques and energy administration components in cloud systems. In addition, different difficulties and research gaps in exchange off amongst reliability and energy efficiency are distinguished for future research and improvements.
