In the age of cloud computing, IT infrastructure becomes virtualised and takes the form of services. This virtualisation results in an increasing de-perimeterisation, where the location of data and computation is irrelevant from a user’s point of view. This irrelevance means that private and institutional users no longer have a concept of where their data is stored, and whether they can trust in cloud providers to protect their data. In this chapter we investigate methods for increasing customers’ trust into cloud providers, and suggest a public penetration- testing agency as an essential component in a trustworthy cloud infrastructure.

Cloud computing is poised to become one of the most important and fundamental shifts in how computing is consumed and used. Forecasts show that government will play a lead role in adopting cloud computing – for data storage, applications, and processing power, as IT executives seek to maximize their returns on limited procurement budgets in these challenging economic times. After an overview of the cloud computing concept, this article explores the security issues facing public sector use of cloud computing and looks to the risk and benefits of shifting to cloud-based models. It concludes with an analysis of the challenges that lie ahead for government use of cloud resources.

Cloud computing has been touted as a revolutionary concept in computing. In this article, we introduce the cloud computing concept, and then discus the implications for the use of the cloud model in higher education. Due to budget constraints and the power of computing “on-demand,” many believe that colleges and universities will be at the forefront of the shift to using cloud-based resources. We examine the impact of cloud computing on both research and university computing operations. We see that globally, this shift is already making a difference in how universities procure and use IT resources. In conclusion, we advance a six-stage Cloud Migration Strategy for introducing and implementing cloud computing in institutions. We also discuss the necessary changes in policies and procurement, as well as security and reliability concerns for institutions implementing cloud computing.
