Article summary

This article presents a detailed literature review on the definition and classification schemes used in cloud computing (Habibo & Mary, 2012). The authors have included about 205 journal articles which researchers have published since the discovery of computing in the research field. The authors have used four categories to classify these articles. Technological issues, domains, business and applications are they criteria that this article uses to classify its literature research. Literature review section introduces the concept of cloud computing and how individuals can different it from grip computing. The article shows different definitions of cloud computing but adopts the National Institute of Standards And Technology (NIST definition as the most appropriate (Habibo & Mary, 2012). The NIST definition also the five vital characteristics of any cloud computing model. The article also uses four models to define the term cloud but public cloud is what defines cloud computing in this context. This research adopts descriptive literature review as the research methodology (Habibo & Mary, 2012). The findings show that the 205 articles classification is the same as those (Habibo, Y. & Mary, 2012) adopted.


  • Using the NIST definition to give the five characteristics of cloud. The characteristics include 0n-demand self-service, broad network access, resource pooling, rapid elasticity and measured service

  • The articles the four definitions of cloud that include public cloud, private cloud, community cloud and hybrid cloud.

  • Using the three layer classification of the computer services. The layers include infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (Habibo & Mary, 2012).

  • Using descriptive literature review approach in conceptualising research areas through proper filtering of best sources based on technology, business issues, applications and conceptualisation of the cloud computing.

  • To get empirical results, the research distributes articles by year, topics and publication outlets

  • The article uses meta-analysis that statistically provides support for this research topic. It synthesises and analyses quantitative results. This model also examines the relationship between dependent variables and independent variables that these others have derived from various existing results or research findings.


  • The authors have based their samples on the various academic publications

  • Cloud computing is mainly industry driven, therefore, other professional articles can also use the same assumption. This hinders the possibility of this article to paint a clear picture of recent developments

  • The article uses referred journals thus its classification scheme does not reflect topic distribution of some conference papers with cloud computing as their scope.

  • The research criteria are also incomplete as some articles do not contain “cloud computing in their abstracts (Habibo & Mary, 2012).

  • The research uses secondary data, as opposed to primary data. Cloud computing is an area that requires raw data to authenticate the theoretical assumptions

Discussion questions

What are the characteristics of cloud computing according to NIST?

Give the four definitions of the term ‘cloud’ using different criteria as NIST suggest?

What are the three layer classifications of computer services?

Is a literature review suitable for technical subjects like IT especially in cloud computing?
