Deadline-based Priority Management in Cloud

In cloud computing, the word “cloud” is used as metaphor for “the Internet,” so the phrase cloud computing means “a type of Internet-based computing” where different services such as servers, storage, and applications are delivered to an organization’s computer and devices through the Internet. Today, cloud computing is on demand that means cloud providers provide their services in pay-as-you-manner. So, there must be a provision that all resources are made available to requesting users in efficient manner to satisfy their needs. Since this resource allocation schemes offered by cloud computing, effective scheduling algorithms are important to utilize these benefits. There are many scheduling algorithms such as task grouping, priority aware, and SJF (shortest job first) to reduce the waiting time and maximize the resource allocation. In this paper, a new algorithm has been proposed namely deadline–first scheduling algorithm, which considers deadline as a crucial factor. Deadline is a major concept in negotiation of SLA in cloud computing to prevent penalties.
