An Enhanced Cloud Adoption Framework for the Financial Services Industry: Case of Family Bank in Nairobi County, Kenya (Published)

Despite potential commercial advantages of Cloud computing, institutions in the Financial Services industry are still hesitant to adopt the technology. The problem is that these institutions opt to put their IT services to cloud because of diverse requirements and concerns that are unique to their environment. Existing frameworks for cloud adoption are too general and though they seem to address some concerns, no single framework is entirely adequate by itself to be applied effectively in the Financial Services Industry. There is therefore an IT problem that exists due to lack of an integrated adoption framework that adequately addresses cloud computing concerns for institutions in the Financial Services Industry who are considering the cloud decision. It is on this basis that this research seeks to develop an enhanced cloud adoption framework that can guide cloud adoption in the Financial Services Sector. The study concluded that technology context, organizational context, IT skill level and cloud knowledge of non IT employees, environmental context and IT governance structure has a positive impact on the adoption of cloud computing in the financial services industry.

A Lightweight Economic Denial of Sustainability (EDoS) Defence in Cloud Network Using Fog Computing (Published)

Fog computing has recently offered benefit able services to Cloud users such as low latency, mobility support, real-time data process, low bandwidth, improved Quality of Service (QoS), and better security. The auto-scaling and measured service characteristics of both Cloud and Fog networks make them vulnerable to cyber-crimes. Consequently, A Economic Denial of Service (EDoS) takes advantage of Cloud users’ vulnerabilities (i.e., software, protocol, IP addresses) to install malware on their device unknowingly. It makes victims captive through a Botnet controller to continuously send unsolicited packets to the data center, which exhausts the Cloud users service subscription (i.e., networking, compute, storage, memory), making the environment financially unsustainable or leading to bankruptcy. “This paper presents EDoS attack challenges and defense approach using Fog network.

There have been many revolutions such as mainframe computers, super computers, web technologies, Internet, grid computing, utility computing, etc even in the computing technologies throughout the history of the world. Cloud computing is another evolutions in the field of computing where computing is delivered as hosted services over the Internet and it has been evolved from the earlier computing technologies by the integration of some of them and removing the obstacles encountered in them as a new technology to the world. Amazon, Google, Microsoft,, are some of the organizations who provide this technology to organizations and personal users. Google provides a service called Google Docs, a widely used example of cloud computing. Even though many studies have examined the overall concept of cloud computing, no previous research has analyzed students’ usage and acceptance of Google Docs in a university setting. The purpose of this paper is to focuses on the factors influencing the use of Google docs as one of the SaaS offering of cloud computing services. The Theory of Planned Behavior was used as the theoretical model for this research in examining what factors influence students to use Google Docs. The interviews (n=20) and surveys (n=316) were deployed to gain a better understanding of this phenomenon. By using hierarchical regression analysis and a correlation matrix to analyze the data, it was found that all three constructs of the Theory of Planned Behavior (Attitude, Subjective Norm, and Perceived Behavioral Control) are significantly and positively correlated with intention to use Google Docs. Further, it was found that Affect, which measures a person’s emotional responses, is also a significant predictor of Behavioral Intention. The findings of this research could be used by multiple stakeholder groups to better understand the factors influencing the usage of Google Docs.
