Virtual Private Server (VPS) Hosting
A
virtual private server, also known as VPS hosting offers the perfect
balance between regular shared hosting and dedicated server hosting. A
VPS is a single hardware node split into multiple virtual machines
(known as VPS or VDS). Virtualization technology, Xen or
OpenVZ, fully separates each of these VPS / VDS / VMs from each other.
This means each VPS is provisioned with a guaranteed set of resources
(CPU, RAM and Hard Drive space) and that each VPS comes with full root
access.
WIKI:
A virtual private server (VPS) is a virtual machine provided by an Internet hosting service.
Although a VPS runs in software on the same physical computer as other
customers' virtual machines, it is in many respects functionally
equivalent to a separate physical computer. A VPS is dedicated to the
individual customer's needs, has the privacy of a separate physical
computer, and can be configured to run server software.
Advantages And Disadvantages OF VPS Server
(VPS hosting) plan can also provide many other advantages such as:
The virtual web server can provide very flexible and convenient usage for the webmaster
Other additional web applications can be easily used by the VPS
Each VPS can be independently rebooted
Every VPS has its own operating system
Every VPS has its own copy of the operating service. Users can install and run any software that needs that operating system
The webmaster can choose any type of operating system and web applications that he requires to run his website effectively
It is as if the webmaster owns the ‘entire’ server without actually using the costlier dedicated web server. The VPS is very powerful and can offer similar features of the dedicated web server at a fractional cost
VPS is quite stable and offers consistent service
The webmaster can have access to the root level of the hosting server
The VPS offers more freedom and features than the shared web hosting server
The webmaster using the VPS can install any software which can be
very beneficial for his growing business. The webmaster can be assured
of highest compatibility between the softwares used and the operating
system used for his VPS
Each VPS is isolated from other VPS sharing the same physical web
server. The resources used by each VPS on the physical web server can be
centrally controlled by the web host
Most VPS use the Linux-based operating system which has proven
track-record of being more stable and secure than the more expensive
Windows-based operating system
VPS can allow the webmaster to host numerous websites very efficiently
A VPS account will usually come with more services and tools from
your web host – much more than what is offered with the shared web
hosting service
As the VPS is isolated from other websites, that is, the VPS does
not interact with other websites present on the physical server, the
security aspect of a VPS is much stronger than the risky shared web
hosting server, where a harmful script or application used by another
webmaster can harm your website
There are many more powerful features that a VPS can offer you over the shared web hosting server
Disadvantages Of Using The Virtual Private Server (VPS)
There are also many other disadvantages associated with using the VPS. They are:
The webmaster must possess high-proficiency in using the VPS to
control the working of the website, the applications used, and the
server resources skillfully
As the VPS usually uses many web applications like the forums,
chatting softwares, e-commerce forms, and other secure applications, if
the webmaster is unable to control these applications professionally,
they can become unmanageable because of the high traffic that they
attract
The hardware resources of the physical web server are still shared
by the many websites that use the server, so your VPS may not be able to
use maximum amount of RAM, disk space (although disk space problems can
be more easily handled by replacing with a bigger hard-disk)
VPS can have limited random access memory (RAM), central processing time, and server disk space
The above facts ascertain the importance of correctly using the VPS.
It has more power, so more responsibility is also needed to control such
powerful system. You can also check the powerful features of the
dedicated web hosting server if your website really needs more power and
greater features. Also, the dedicated web server offers you the entire
physical server’s powers and features, and as in the case of the VPS,
your server’s physical resources like the RAM are not shared with other
users.
Remember that the great powers and features of the dedicated web
server are available for expensive fees to you. So, if your website
really needs more powers and features than the shared web hosting
server, and if your website is not a very critically important
e-commerce website, then opt for the VPS.
