virtualisation

Virtualisation is a broad term and can be applied to many systems both inside and outside of IT. It describes the ability to break a system into elements and then to simulate and control the interactions between them. Elements can be moved or even changed and the system keeps working. If applied well, this can yield massive advantages for the system design in terms of flexibility.

Clouds

Cloud Computing is a term which has come into fashion over the past few years. It means different things to different people and is used so broadly that it can be hard to make sense of exactly what it is. There is debate as to whether "Cloud" is even a new phenomenon or just a new name for a trend in IT which has been happening for many years - namely to think of IT as providing services - rather than consisting of a system of hardware and software solutions.
