Cloud computing has been a hot topic in the research community since 2007. In cloud computing the online services are conducted to be pay as you use. Services need not to be in a long term contract with service providers. Service level agreements (SLAs) are agreements signed between a service...

When economic times get tough, businesses worldwide are compelled to review their organizational expenses and priorities and to strategically consider how best to save. Traditionally, Information Technology (IT) department is one area that would be affected negatively in the review. To better...

We introduce three new mechanisms that allow trust to be built into cloud computing called the Private Virtual Infrastructure (PVI), the Locator Bot (LoBot), and the Trusted Virtual Environment Module (TVEM). Cloud computing requires that organizations trust that a service provider’s platforms...

Cloud computing has enabled users to access various resources and applications as a service and in return pay the provider only for the time for which they are used. Service Level Agreements (SLA) are formed between the user and provider to ensure that the required services and applications are...

This paper aims to provide a brief review of cloud computing, followed by an analysis of cloud computing environment using the PESTEL framework. The future implications and limitations of adopting cloud computing as an effective eco-friendly strategy to reduce carbon footprint are also discussed...
