ABSTRACT

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.

摘要

云计算吸引了许多企业将其应用程序迁移或部署到云平台中，从而降低了运营成本。在本文中，我们研究了将企业应用程序迁移到云中的合理资源分配。首先，我们为企业应用程序迁移的资源分配制定了效用最大化模型的概括形式。归纳形式的优化问题由于其非严格的凸度和非分离性而难以解决。我们应用逐次逼近法研究泛化形式模型，并提出了一种基于梯度的资源分配方案来解决逼近问题。然后，我们通过数学方法分析其性能，并通过一些数值示例进行说明。
