Cloud computing is currently being provisioned and utilized by organisations in various and unstandardized approaches depending on the contract between the service provider and the end-user. The problem in this approach has been observed in the long-term cost, management overheads, and the environment sustainability associated with ICT usage. One method is to treat cloud computing services as a commodity via a metered billing approach, similarly to the way users pay for water, gas and electricity. This approach has shown a potential for sustainability and environmental benefits. These advantages have ranged from cost reductions, power optimisation, and simplifying in-house management processes. The objective of this paper is to examine the sustainability and environmental aspects of cloud computing services for non-expert users. The paper conducts an ICT energy consumption analysis and concludes a decision-making framework for the purpose of standardizing cloud computing sustainability aspects for non-expert decision-makers. The paper argues that certain cloud characteristics such as resource pooling, elasticity, multi-tenancy and service consolidating, can have a positive impact on any organisation with a medium or low-level ICT capacity in order to reduce energy consumption and gain future sustainability advantages.
