将遗留软件系统迁移到云的挑战：一项实证研究（CS SE）---用户7095611

将现有遗留系统转移到云平台是一个困难和高成本的过程，可能涉及技术和非技术资源和挑战。 有证据表明，由于缺乏对云计算迁移的理解和准备，导致许多迁移失败，无法实现组织的目标。 本文的主要目标是从再工程流程的角度，确定将遗留系统移动到云平台的最重要的挑战性活动。 通过自下而上和自上而下的分析相结合，从现存的云计算文献中得出了一组常见的活动。 这些都表示为一个模型，并验证使用的104名候选人和随机选择的领域专家从不同的行业部门。 采用网络调查问卷收集数据，利用SPSS样本T检验进行分析。 这项研究的结果突出了云迁移工作遗留下来的各种角色应该解决的最重要和关键的挑战。 这项研究提供了对这一过程的全面了解，包括共同发生的活动、关注的问题和建议。 此外，这项研究的结果构成了进行这种过渡的实际指南。 本指南与平台无关，独立于任何特定的迁移场景、云平台或应用程序领域。

原文题目：Challenges in migrating legacy software systems to the cloud an empirical study

原文：Moving existing legacy systems to cloud platforms is a difficult and high cost process that may involve technical and non-technical resources and challenges. There is evidence that the lack of understanding and preparedness of cloud computing migration underpin many migration failures in achieving organisations goals. The main goal of this article is to identify the most important challenging activities for moving legacy systems to cloud platforms from a perspective of reengineering process. Through a combination of a bottom-up and a top-down analysis, a set of common activities is derived from the extant cloud computing literature. These are expressed as a model and are validated using a population of 104 shortlisted and randomly selected domain experts from different industry sectors. We used a Web-based survey questionnaire to collect data and analysed them using SPSS Sample T-Test. The results of this study highlight the most important and critical challenges that should be addressed by various roles within a legacy to cloud migration endeavour. The study provides an overall understanding of this process including common occurring activities, concerns and recommendations. In addition, the findings of this study constitute a practical guide to conduct this transition. This guide is platform agnostic and independent from any specific migration scenario, cloud platform, or an application domain.
