The concept of cloud computing is going to reorganise the tenets of enterprise IT. Cloud computing sounds like traditional IT outsourcing, but the difference is that this is not just about ownership of IT staff and resources, but a new way of organising, acquiring, and paying for IT infrastructures and services, with outsourcing being just part of the mix. Characterised this way, the move towards cloud computing seems certain, even if enterprises are reluctant to move forward too rapidly right now. Only a few enterprises are actually adopting cloud services at the moment, but the fact that any are is notable. This paper discusses cloud computing's progress within the enterprises.
