Virtualization is the process of creating a virtual version of something like the
operating system, or a software, or a server, a storage space or a network resource.
Virtualization is considered to be the fundamental technology associated with the enabling of
the development as well as the operation of cloud computing services. This technology is
associated with bringing a lot of advantages as well as disadvantages some of them have been
listed below:
Advantages of Virtualization
 Reduction in excess spending as only few numbers of servers are required and no need of
extra hardware. Besides the lifespan of the existing hardware increases and the cost of
energy required decreases.
 Easy backing up and recovery at times of disaster (Chamberlin et al., 2017). The recovery
process becomes quicker along with being swift and accurate. Less manpower and
equipment’s are required.
 Ensures business continuity due to increased mobile workforce. Virtualization is
associated with providing access to the software, files and communications anywhere and
anytime.
 IT operations becomes more efficient as the jobs becomes easier and this also provides
the technicians with easy facility of installing and maintaining the system (Mousa &
Shiratuddin, 2015). This can be done in less time as required by the non-virtual systems.
Disadvantages of Virtualization
 Responsible for Upfront costs as huge investment is required to adopt the virtualization
software, along with the requirement of additional hardware (Kumar & Charu, 2015).
This depends on your existing network.

 Software licensing considerations is another disadvantage that is of less problem because
of the adaptation of the virtualization by different software vendors however the software
also needs to have a clear understanding of the technology as well.
 Implementation and management of the virtualized environment requires expert IT staff
whereas from the user side a typical virtual environment would be operating as a non-
virtual environment.
