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.
