Survey on scheduling in hybrid clouds

Cloud computing provides infinite access to on demand resources, this is true in case of public clouds but not in case of private clouds. As public cloud charges on usage basis, private clouds are owned by user. Composition of private and public cloud is known as hybrid cloud. In hybrid cloud task scheduling is a complex process as jobs can be allocated either in private cloud or public cloud. Deciding which resource should be taken on lease from public cloud into private cloud to complete the task is decided by number of scheduling algorithms. In this paper, we look at the various scheduling techniques and algorithms that are used in hybrid cloud and these are classified according to their optimization criteria and features provided by them. This paper is composed of five parts as introduction, scheduling process in hybrid clouds, types of scheduling techniques with their classification, execution cost parameter and conclusion is given in the end.
