Enterprises can reduce the computational burden and costs substantially by migrating and deploying their partial or even whole applications to the cloud, so as to promote and realize their digital transformation. In this article, we study the following problems in the migration and deployment of enterprise applications: i) How the migration time factor influences application migration indirectly? ii) What is the optimal deployment strategy for multiple applications? In this regard, many existing schemes that aim to optimize the economic cost can neither model the optimal migration strategy nor the optimal deployment resource allocation appropriately for enterprise applications. To tackle these limitations, first, this article aims at minimizing migration time by allocating the bandwidth of the access links for applications migration and formulates a strictly convex optimization problem. After that, the article concentrates on modelling the deployment interactions for resource allocation between enterprise application and cloud physical machines as a non-convex optimization problem. The successive approximation method is used to approximate the problem into a series of strictly convex optimization problems and an algorithm is proposed to achieve the optimal resource allocation for applications deployment problem. Numerical results illustrate the effective performance of the proposed schemes of enterprise application migration and deployment in comparison with other methods.

用于将多类企业应用程序迁移和部署到云中的优化框架

企业可以通过将部分甚至全部应用迁移部署到云端,大幅降低计算负担和成本,从而促进和实现数字化转型。在本文中,我们研究了企业应用程序迁移和部署中的以下问题: i) 迁移时间因素如何间接影响应用程序迁移?ii) 多个应用程序的最佳部署策略是什么?在这方面,许多旨在优化经济成本的现有方案既不能为最佳迁移策略建模,也不能为企业应用程序适当地建模最佳部署资源分配。为了解决这些限制,首先,本文旨在通过为应用程序迁移分配访问链路的带宽来最小化迁移时间,并制定了一个严格的凸优化问题。之后,文章重点将企业应用程序与云物理机之间资源分配的部署交互建模为一个非凸优化问题。利用逐次逼近法将问题逼近为一系列严格凸优化问题,并提出了一种算法来实现应用程序部署问题的最优资源分配。数值结果说明了与其他方法相比,所提出的企业应用程序迁移和部署方案的有效性能。本文着重于将企业应用程序和云物理机之间资源分配的部署交互建模为一个非凸优化问题。利用逐次逼近法将问题逼近为一系列严格凸优化问题,并提出了一种算法来实现应用程序部署问题的最优资源分配。数值结果说明了与其他方法相比,所提出的企业应用程序迁移和部署方案的有效性能。本文着重于将企业应用程序和云物理机之间资源分配的部署交互建模为一个非凸优化问题。利用逐次逼近法将问题逼近为一系列严格凸优化问题,并提出了一种算法来实现应用程序部署问题的最优资源分配。数值结果说明了与其他方法相比,所提出的企业应用程序迁移和部署方案的有效性能。利用逐次逼近法将问题逼近为一系列严格凸优化问题,并提出了一种算法来实现应用程序部署问题的最优资源分配。数值结果说明了与其他方法相比,所提出的企业应用程序迁移和部署方案的有效性能。利用逐次逼近法将问题逼近为一系列严格凸优化问题,并提出了一种算法来实现应用程序部署问题的最优资源分配。数值结果说明了与其他方法相比,所提出的企业应用程序迁移和部署方案的有效性能。
