This dependency has created a fundamental business risk to them. 
That said, Cloud computing is an established and trusted model for the delivery of IT services in both the public and private sectors. The UK government has stated: 

“Cloud offers the cost-effectiveness, agility and security necessary to support the on-going Digital Transformation of Government services.” 

There is however a real lack of awareness and understanding of the pros and cons when considering a move to The Cloud and this is inhibiting the rapid adoption of Cloud services in both the public and private sector. 

So, why move to The Cloud? Well first we must consider what we mean by cloud. Which cloud deployment model is needed, Hybrid Cloud, Private Cloud, Public Cloud or even Community Cloud? Numerous other questions also arise:

Are we considering PaaS (Platform as a Service), IaaS (Infrastructure as a Service) or perhaps SaaS (Software as a Service)? How do you choose or assess a Cloud Service Broker, Internet Service Provider or Global Public Cloud Provider?

Clearly, beyond the obvious economic reasons for a move to The Cloud, many aspects need to be weighed carefully. Understanding exactly who holds sovereignty and Jurisdiction over your data is essential when entering in to contractual arrangements. The following points must be considered prior to any move to The Cloud.

	Data Security
	Commercial and Contractual considerations
	Privacy considerations
	The Future
	Safe Harbour renegotiations

Are your customers ready for these changes?
