Abstract:
There are three focal questions addressed in this thesis: • Firstly whether large organisations, particularly public sector or governmental, can realise benefits by transitioning from the ICT delivery models prevalent in the late 2000s to use Cloud computing services? • Secondly, in what circumstances can the benefits best be realised, and how and when can the associated risk reward trade-off be managed effectively? • Thirdly, what steps can be taken to ensure maximum benefit is gained from using Cloud computing? This includes a consideration of the technical and organisational obstacles that need to be overcome to realise these benefits in large organisations. The potential benefits for organisations using Cloud computing services include cost reductions, faster innovation, delivery of modern information based services that meet consumers' expectations, and improved choice and affordability of specialist services. There are many examples of successful Cloud computing deployments in large organisations that are saving time and money, although in larger organisations these are generally in areas that do not involve use of sensitive information. Despite the benefits, by 2013 cloud computing services account for less than 5% most large organisations' ICT budgets. The key inhibitor to wider deployment is that use of Cloud computing services exposes organisations to new risks that can be costly to address. However, the level of cost reduction that can be attained means that progressive deployment of Cloud computing services seems inevitable. The challenge therefore is how best to manage the associated risks in an effective and efficient manner. This thesis considers the origin and benefits of Cloud computing, identifies the barriers to take up and explores how these can be overcome, and considers how cloud service brokerages can potentially develop further to close the gap by building new capabilities to accelerate take-up and benefits realisation.
