The emergence of the Web in 1990 gave rise to cloud computing; a disruptive innovation in the bird’s-eye view of information technology. Cloud computing essentially sidesteps the need for capital investments in hardware and expensive information technology, yet has many hurdles to overcome. The purpose of this review is to identify the most discussed topics and relevant theories, while also focusing on the influential factors of cloud adoption in small and medium enterprises. This paper provides an investigation of 25 conference papers, articles, and review papers listed in Scopus and 67 articles from popular publications like Emerald Insight, Elsevier, and Sprouts. Articles are comprehended in three stages: (1) word frequency query, (2) cluster analysis, and (3) narrative review. Thus, the research design cumulatively covers 92 articles and uses two review methods; systematic and narrative. The synthesized outcome of the literature identifies four interrelations of topics; cost-services, adoption-factors, technology-business, and cloud-computing, while pinpointing at “policy” as an outlier. Findings highlight the applicability of influential factors such as “cost” and “flexibility” to multiple benefits of cloud computing, both tangible and intangible. The results encapsulate the synthesis of theoretical models (Technological-Organization-Environment framework and Technology Acceptance Model). Other summarizations are their embedded constructs, impediments, and cloud economics. The roles of other stakeholders enhance cluster-wise e-readiness for all-round benefits. Practitioners can leverage cloud benefits to augment successful adoption and diffusion. Researchers can look forward to addressing gaps in the area of policy, risks, and service models to facilitate the business aspect of cloud technology.

1990年Web的出现催生了云计算。鸟瞰信息技术的颠覆性创新。云计算从本质上回避了对硬件和昂贵信息技术的资本投资的需求，但仍有许多障碍需要克服。这篇综述的目的是找出讨论最多的主题和相关理论，同时还将重点放在中小型企业采用云的影响因素上。本文对Scopus上列出的25篇会议论文，文章和评论文章以及Emerald Insight，Elsevier和Sprouts等流行出版物中的67篇文章进行了调查。文章的理解分为三个阶段：（1）词频查询，（2）聚类分析和（3）叙述性复习。因此，研究设计累计涵盖92篇文章，并使用两种审阅方法；系统性和叙事性。文献的综合结果确定了主题的四个相互联系。成本服务，采用因素，技术业务和云计算，同时将“策略”定位为异常。调查结果强调了诸如“成本”和“灵活性”等影响因素对云计算的多种有形和无形收益的适用性。结果封装了理论模型（技术－组织－环境框架和技术接受模型）的综合。其他概述是它们的嵌入式构造，障碍和云经济学。其他利益相关者的角色增强了群集的电子就绪性，从而获得了全面的好处。从业人员可以利用云的好处来增加成功的采用和传播。研究人员可以期待解决政策，风险和服务模型领域的差距，以促进云技术的业务发展。
