The term virtualization
and cloud computing goes hand in hand, there are some differences between them,
but there are similarities too.
What are they? How are
they different? Before going to explain that; we should have basic knowledge
about- what these terms actually mean.
Virtualization - it is
a single computer managing various machines. In other words, it can be said it
provides multiple servers on the hardware configuration, helping in achieving
high performance, reduces capital costs and etc.
What is a cloud
computing?
It can be explained in
just one line- a person lives in a hotel rather than in a house is a cloud computing.
Or it can be understood, there are various softwares on the cloud, a person
uses them, but when his computer crashes- those software doesn’t i.e. others
can still use those software. So, it is “collection” of computers and servers
on the internet that can be accessed publically. Obviously there can be private
clouds but right now we should take on a general term.
On the whole, Virtualization
is a key component of the cloud, but cloud computing is not only “virtualization”.
It usually means- “we pay for what we see” not for everything else we have been
given and we are not using. It helps in “user scalability”.
So, it can be summed up
as- virtualization is one physical
computer pretending to have multiple computing paradigms whereas in cloud computing,
there are many computers who pretend to be “one”.
