Cloud computing has become one of the newest and most popular topics in the field of the Internet. Pricing is one of the main factors that can affect the successful implementation of cloud computing. Due to the large volume of research conducted in this field, the purpose of this study is to review the cloud computing pricing literature using a Computational Literature Review (CLR) and identify influential trends in this field. For this purpose, the publication and citation trends are first identified. The most influential authors, journals, and articles are then determined using citation analysis. Next, the structure of the co-occurrence network of keywords is analyzed using three centrality measures degree, betweenness, and closeness. Finally, the thematic trends are identified using a positional analysis based on centrality measures. According to the obtained results, research in this field has grown significantly. Keywords such as edge, computer architecture, and distributed computing have recently come to the fore. Also, words such as model, energy, allocation, strategy, auction, design, and reliability have been among the most influential in this field. The positional analysis indicates that the researchers are trying to overcome resource scarcity through three lines of work: resource provision, resource allocation, and resource distribution. Trends show that the cloud industry is highly attractive and will also have high growth. In the future, we will also see an increase in the use of value-based pricing methods in cloud computing and research in this area.https://dorl.net/dor/20.1001.1.20088302.2022.20.4.12.1

OPAC visibility, implementation of the cloud system and challenges of its adoption are the variables that define the crust of the research. The study, compartmentalizing the Nigerian University libraries, adopted the quantitative methods employing the use of observation and survey. A two-month long observation of the websites and OPAC of the studied universities was undertaken. The non-probability sampling - precisely purposive sampling - was deployed while the entire one hundred and sixty (160) Nigerian universities – as at 2018 – served as the sample size for the study. A questionnaire was designed to collect primary data on the availability of OPACs and adoption of cloud hosting in Nigerian university libraries. This was administered electronically via the email-boxes of virtual/systems librarians. Significant trends noticeable in the research findings include low visibility, in-house hosting of OPAC and indifference to the adoption of cloud computing with hosting (subscription) fee, downtime in internet connectivity and fear of vulnerability to hackers’ attack being the significant challenges. It is recommended that stakeholders should leverage on the existing consortium (platform) facilitated by Nigerian Research and Education Network (NgREN) to benefit from the economy of scale in addition to collaboration with relevant global agencies. Furthermore, a synergy between the librarians and the ICT units should be strengthened for a better understanding of the technical challenges in order to provide appropriate solutions to them.
