摘要:

将现有的遗留系统迁移到云平台是一个困难且成本高的过程,可能涉及技术和非技术资源和挑战。有证据表明,缺乏对云计算迁移的了解和准备是导致许多迁移失败以实现组织目标的原因。本文的主要目标是从再工程过程的角度确定将遗留系统迁移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,从现有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,并验证了人口的104个入围和随机选择的领域专家从不同的行业部门。我们使用基于Web的调查问卷收集数据,并使用SPSS样本T检验进行分析。这项研究的结果突出了最重要和最关键的挑战,这些挑战应该由传统云迁移工作中的各个角色来解决。该研究报告提供了对这一进程的全面了解,包括共同发生的活动、关切和建议。此外,这项研究的结果构成了一个实际的指导,进行这种过渡。本指南与平台无关,独立于任何特定的迁移场景、云平台或应用程序域。关键词云计算,遗留系统,云迁移,云迁移过程

英文摘要:

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. Keywords. Cloud Computing, Legacy Systems, Cloud Migration, Cloud Migration Process
