Abstract
Cloud computing recently emerged as a new paradigm that aims to deploy services via Internet. Under hybrid cloud environment, cloud bursting is a technique that combines local (organizations or in-house) resources with public cloud resources, these resources are leased based on a pay-per-use basis. It used to process the overload work within local resource or to accelerate the execution time of distributed applications with respect of the required level of QoS, also to achieve the efficient use of private resources. When Cloud bursting is applied, the important issues are determining how many and which type of resources will be provisioned. Also, the important issues that should be considered before cloud bursting decision are which workload will be burst to public cloud and when these resources will be released. These issues attract the attention of researchers to tackle them. In this paper we intend to review the recent researches that concern on cloud bursting and resource provisioning. We will explore how each study address the problem, what are the proposed solutions and what are the differences between them, the main researches are compared interms of several criteria such as type of application, which was targeted by the research, environment that used to implement the experiment, results, and limitations.
