									Proud to Present: Virtual Private Server (vps)

The VPS was invented to enable small businesses or
individuals enjoy a (dedicated) server of their own in a cost of
a little
more than a basic (shared) hosting and without purchasing
any piece of hardware. The idea is simple: the supplier
allocates a memory block and defines it as a server by
installing all the software environment needed for it.

Cases you don't need a VPS and can do well enough with a
shared hosting:
1.In cases you have a low to medium traffic website .
2. In cases you don't have any Linux experience and prefer a
simple administration panel.
3. In cases a gap of $25-$40 may be significant for you.

Cases you would enjoy a VPS more than a shared hosting:

1. When you need a full server administrator access and can't
do well with the very limited administrative rights given to you
in a shared hosting. For example: if you need to install SSL
(encryption) for your website, or if you need to modify the PHP
engine configuration.
2. When you have heavy traffic coming in to your site. In case
of a shared hosting, this can cause trouble (the bandwidth is
more limited than in a VPS).

Now, what are the differences between a VPS and a full
dedicated server:
1. Though a VPS is a server, the fact that it uses the same
hardware with other VPS's, limits a little the flexibility of the
administrator regarding the server's configuration.
2. For the same reason, the surfing to your site can be
sometimes a beat slower, because other sites using the same
hardware might be flooded by traffic at that moment.
3. Using a VPS, you save a respectable sum of money due to
the lack of hardware required and due to the fact that you
don't have to maintain regularly the hardware.
4. Resources on demand - using a VPS, you can easily enlarge
vital resources like: RAM & fixed memory. Using a dedicated
server, you have to purchase an additional hardware device in
such a case.

Summary - a VPS is an hybrid of two: the large dedicated
server and the primitive shared hosting. If you have a modest
website (no video or complex graphics) with a traffic of no
more than a couple of thousands a day, you should do fine
with a shared hosting program. If you represent a huge portal
having tens of thousands visitors a day and presenting heavy
data (graphics, video), it seems that you won't escape a heavy
expenditure on a dedicated server. If none of the above is
relevant to you, would you consider a VPS?..
