Disadvantages of Hypervisors
Some of the reasons some people shy away from using virtualized environments include the
following:
 High implementation cost: Creating a virtual environment requires the purchase of both
hardware and software. Other times, devices may need to be manufactured, developed or
purchased in order to implement the infrastructure.
 Availability issues: People and organizations who utilize virtualization often worry about
what will happen to their data in the event that their assets are unavailable. If this were to
happen, the organizations might struggle to maintain their positions in the industry. There’s
also the issue of third-party providers making the control of data almost impossible.
 Requires cohesiveness of all links: Being the sole tenant means you are in full control of
your operations. With virtualization, you don’t have such control because there are quite a
number of links required to work seamlessly to achieve one goal. If one of the links is
compromised, the entire server will not function optimally.
