Utility maximisation for resource allocation of migrating enterprise applications into the cloud

Cloud computing has attracted many enterprises to migrate or deploy their applications into the cloud platform so as to reduce their operational costs. In this paper, we investigate the reasonable resource allocation for migrating enterprise applications to the cloud. We first formulate a generalisation form of utility maximisation model for resource allocation of enterprise applications migration. The generalisation-form optimisation problem is difficult to resolve due to its non-strict convexity and non-separation. We apply the successive approximation method to study the generalisation-form model and present a gradient-based resource allocation scheme to solve the approximation problems. Then, we analyse its performance through mathematical method and also illustrate with some numerical examples.
