A large number of systematic reviews (SRs) studies have been performed in the cloud computing field, demonstrating miscellaneous outcomes and utilizing different approaches. Accordingly, a meta-review of cloud SRs is needed to appraise the results of such studies and create an integrated understanding. The paper aims to discuss these issues.,A tertiary study was conducted using a systematic method to analyze SRs including two stages: searching and screening the SRs and thematic synthesis of results. As a qualitative data management tool, Nvivo software was used to support the research process, for data coding and synthesis.,First, by searching electronic sources between the year of 2011–2016, out of a total of 142 identified articles, 94 articles were included according to pre-determined criteria, of which 76 articles were approved after qualitative evaluation. In the second stage, identifying the research themes, a map of the concepts and issues related to each theme was drawn up. The analysis shows that the quality of articles has improved but can be further enhanced using methodological guidelines as well as supporting tools. The research has focused more on the technical aspect, although there is an equal demand for synthesizing of cloud governance concepts.,This is the first tertiary study which presents the main research themes and concepts of cloud SRs in form of thematic maps by using the thematic synthesis and SR methods. This paper also provides some recommendations to improve reviews after evaluating the quality of papers. This study can support reviewers for future SRs in the field and also helps practitioners and managers to have a better understanding of different aspects of cloud computing.

基于系统评价的云计算主题映射：第三级研究

在云计算领域已经进行了大量的系统评价（SR）研究，展示了其他结果并利用了不同的方法。因此，需要对云SR进行元审查以评估此类研究的结果并建立综合理解。本文旨在对这些问题进行讨论。采用系统的方法对SR进行了第三次研究，包括两个阶段：搜索和筛选SR和结果的主题综合。作为定性数据管理工具，Nvivo软件被用于支持研究过程，以进行数据编码和合成。首先，通过搜索2011-2016年之间的电子资源，在总共142条已识别的文章中，有94条是根据预定标准包括在内，定性评估后，批准了76篇文章。在第二阶段，确定研究主题，绘制与每个主题相关的概念和问题的地图。分析表明，文章的质量有所提高，但可以使用方法指南和支持工具进一步提高。尽管对云治理概念的合成有同等需求，但研究仍侧重于技术方面。这是第一项第三级研究，它通过使用专题图以专题图的形式介绍了云服务SR的主要研究主题和概念合成和SR方法。本文还提供了一些建议，以在评估论文质量后改进评论。
