A Survey on Latency Reduction Approaches for Performance Optimization in Cloud Computing

Cloud computing is a novel paradigm where resources are provisioned on demand. The ever-increasing status of cloud hypothesis and the budding concept of federated cloud computing have enthused research efforts towards intellectual cloud service selection. Due to the improving status of cloud computing there are a deluge of enterprises that are using cloud environment. In the recent years cloud has acquired impetus in different organizations, therefore cloud performance evaluation and its proper analysis is of utmost importance and can help users make right decisions. Certain key performance factors in cloud include latency, bandwidth, recovery, availability, scalability, security and storage. Latency occurs in cloud due to delay in network because of congestion. If an application takes a larger amount of time to wait for a response from a data centre, performance will suffer due lack of proper bandwidth utilization. Thus, in this paper we present a view on the other major cloud performance factors and also discuss the dependency of cloud performance on these factors. We also discuss different approaches for reducing latency for performance optimization in cloud computing.
