9. Conclusion Cloud computing offers a new model for remotely delivering a range of ICT services that can be provisioned in a “metered” pay-as-you-go way. In doing so it provides scalability and convenience for the end users. Most importantly, it obviates the need by users to invest heavily in hardware and software and spares them all the other associated expenses that go with such investments (e.g., staff, upgrades, maintenance). Using cloud computing for healthcare provision provides opportunities for cost savings and innovative solutions. Some examples were provided in this article that demonstrate the growing interest in this area by both healthcare and cloud providers. A small and limited “proof of concept” case study based on a successful e-Health pilot project (using a simulator) implemented in a London hospital was presented in this article to demonstrate the advantages that potential “real” patients(and their relatives) can derive from having such cloud system in place .Despite its growing popularity, as demonstrated in this article, there are still some serious and real concerns relating to cloud computing such as security, outages and vendor-locking. Some of the seissues are being addressed by cloud vendors and other organizations that are keen to establish standards and best practices. The potential of using cloud computing in delivering 21st century healthcare offers many exciting possibilities for professional sand organizations working in this field. However, the cloud, a sa reliable IT service paradigm, needs to overcome the challenges that currently prevent many companies from adopting it. Contrary to conventional wisdom, research suggests that small local cloud providers are perceived to be more reliable and more trusted by enterprises than large and well established ones. For healthcare providers that see potential merit in adopting a cloud solution, choosing the right cloud provider will be the real challenge.
