2. Data Redundancy
If an organization uses virtualization and copy, their data in multiple
partitions then it helps them to keep their data safe. If the one partition
is lost or if the data in the one partition gets deleted, they can still
recover it is using the other partition.
3. Usage of Virtualization as a Web Server
To get a web server to host a website is a costly task, virtualization can
help in this if a server is virtualized then a dedicated part of the server
can work as a web hosting platform for the website.
If multiple partitioned is done then it can host multiple websites all with
different requirements, such as different resource configuration,
operating systems and we can customize the partition as per the
requirement of the website.
Advantages
There are various advantages as follows:
o Less use of physical and costly resources since virtualization helps in
sharing and distributing limited resources.
o If we do virtualization, we are basically performing a live migration of data
with the help of software
o Virtualization also helps in reducing the use of physical devices
o The virtualized partition of the server can run its own software and OS
independent of the other partition and the actual physical server.
o This helps in reducing the cost of the servers
o If virtualization is done, then it is quite easy to back up the current state of
the server and restoration is also quite easy if the server runs into some
trouble
o Virtualization also helps in reducing the energy and power consumption.
o If the server is partitioned into multiple parts using virtualization, then it
can help is consolidating the server.
o Through virtualization, it is easy to install software and security updates
and patches quite easily.
o Virtualization of the server is the easiest and cost-effective way for hosting
websites.
