Does a proprietary solution automatically mean vendor lock-in?

The dread of any IT manager is in making a significant purchase of hardware or software to then find that they are ‘locked in’ to one supplier. But is this still the case, asks analyst Clive Longbottom, in this report from Quocirca.
Much has been said about the commoditisation of IT – servers are just processors in a box; network equipment is just ports; storage is just a collection of drives. Virtualisation and cloud computing have done away with all the need for complexity at the hardware level – hence the argument that the physical platform can be cheap and cheerful.
Nothing could be further from the truth, unfortunately. Although abstraction through virtualisation does provide far greater flexibility to an IT platform, there will still remain solid dependencies between the abstracted virtual and the physical layers.
