ONLINE RESOURCES SCHEDULING UNDER CONCAVE PRICING FOR CLOUD COMPUTING-CLOUD COST OPTIMIZER

         Cloud computing is an evolving paradigm, where new service providers are frequently coming into existence, offering services of similar functionality. Major challenge for a cloud customer is to select an appropriate service provider from the cloud marketplace to support its business needs. How-ever, service guarantees provided by vendors through SLAs contain ambiguous clauses which makes the job of selecting an ideal provider even more difficult. As customers use cloud services to process and store their individual client’s data, guarantees related to service quality level is of utmost importance. For this purpose, it is imperative from a customer’s perspective to establish trust relationship with a provider. Moreover, as customers are outsourcing their businesses onto a third-party cloud, capability or competence of CSP determines if former’s objectives are going to be accomplished.
