Virtualisation and Consolidation are two aspects of simplification of hardware and Data centers,servers etc, although these methods may appear to be complication to novices.
Virtualisation is about higher utilisation of resources,which include compute,storage and network, this results in Horizontal scalability,it is also described as the process of a aggregrating smaller resources towards a cumulative power of all.
One of the breakthrough's of virtualisation is in changing the old computing paradigm of one application per server.
Virtualisation makes it possible for mutually incompatible application, ie applications which are known to cause problem when working together to run on a single server.
This is brought about by a server to work as a file which is untouched by parallely running servers which are similar files,Advancements have made it possible to have different OS and different versions of OS to run concurrently as independent servers ie as Virtual servers on a physical server.Each of these virtual servers are OS & Application bundled with virtual hardware into a single file which is capable of working independently from other similar virtual servers.
Consolidation is about pooling resources to enable greater utilisation of assets with greater flexibility.Its about optimising technologies to achieve cost savings, Improve performance and mitigate risks.This involves physical planning,optimisation and physical migration of systems and facilities, and applied on Data centers,storage,applications, services and network.

Virtualisation
Virtualisation is about taking the abstract of the physical hardware and providing for software,this is making a single server to do the job of multiple servers.By Virtualisation a server can be made to run as a software application on a server
and even have multiple servers running on a single server it also possible to have different os based servers running simultaneously from a single physical server.
Virtualisation brings in hugh saving in cost as it reduces the amount of Hardware which in itself is cost, and then space for the virtual servers,Power interms of power consumed and also cooling,Software licenses in some cases.
Virtualisation is categorised in various forms.
Platform Virtualisation which is about hiding the physical hardware from the software but provides the abstract of it.
When it comes to software products on virtualisattion, VMware dominates over any other company, it also need to be mentioned that virtualisation is in experimental satage with many of the vendors , Sun microsystems have come up with N1 grid container which is capable of running mutually incompatible programs.
VMware Infrastructure 3 virtualises servers,storage and network to transform your IT infrastructure into an automated, on a single computer.
Streamlining of IT infrastructure management using virtualisation results in server consolidation, and improve business continuity due to lesser downtimes.
VMware server is a hosted virtual server running on a physical machine, VMware server enables splitting of a physical server into multiple virtual servers.
