Big Data computing and clouds: Trends and future directions

Abstract

This paper discusses approaches and environments for carrying out analytics on Clouds for Big Data applications. It revolves around four important areas of analytics and Big Data, namely (i) data management and supporting architectures; (ii) model development and scoring; (iii) visualisation and user interaction; and (iv) business models. Through a detailed survey, we identify possible gaps in technology and provide recommendations for the research community on future directions on Cloud-supported Big Data computing and analytics solutions.

Big Data using Cloud Computing - Opportunities for Small and Medium-sized Enterprises

“…According to Bello-Orgaz, Jung and Camacho (2016), some of the challenges related to velocity include the Introduction of previously stored legacy collection of data and different forms of streamed data from multiple sources. Veracity refers to the level of trust and reliability associated with the data given its source (Assunção et al, 2015). According to Jamil et al (2015), data veracity has four components, namely, trustworthiness, availability, accountability, and authenticity.…”

“…An in-depth analysis of the benefits of the technology, its relevance, and alignment of deployment of this new technology with the strategic business objectives of the company needs to be conducted. Big data provides the ability to companies to analyze data and have a better understanding of the several key areas, including customer behavior, offer customized services and gain insights into issues to which they had no access before (Assunção et al, 2015). Several instances of failure of new technology initiatives in companies exist which demonstrate that new technologies cannot succeed unless there is a strategic alignment between the business and the technology objectives.…”

“…Private clouds allow the cloud infrastructure to be deployed exclusively for use by a single organization. Private clouds are suitable for organizations that require highest level of control over security and privacy (Assunção et al,2015). SMEs would typically not require a private cloud.…”

“…Public clouds can be deployed off-site over the Internet and are available to the general public. The advantage of public clouds is that they offer high efficiency and resources at low cost (Assunção et al,2015). This type of cloud infrastructure could be quite useful for SMEs which often have limitations with budget and manpower.…”

“…Cloud computing resources and techniques can be leveraged to address the traditional problems associated with fault tolerance and low performance causing bottlenecks to using big data (Chen & Zhang, 2014). According to Assunção et al (2015), the area of big data using cloud resources is moving at a rapid pace. Small-and Medium-sized businesses (SMEs) often lack the resources to invest significantly on technology needed to leverage big data.…”
