Virtual Servers vs. Virtual Hosting
There are essentially two types of hosting solutions available:
Virtual Hosting and Virtual Servers. Though the terms seem similar,
the underlying functionality of the two solutions is very different.
Your Internet site is very likely an integral part of your business,
therefore understanding the differences between Virtual Hosting and
Virtual Servers can have a significant impact on your hosting decision.
A decision that can be as important as choosing what content you place
on your site.
Web Hosting solutions consist of two components, namely:
- the hardware (such as the CPU, memory, disk drives, etc), and
- the software (i.e. the web, ftp, and pop servers, the e-mail
gateway, and any third-party applications such as CGI scripts).
In a "Virtual Hosting" environment both the hardware and the software
are configured and customized by the site administrators. Therefore, the
client is left with little to no control over how his or her Internet
Services behave. This kind of inflexible solution simply shares the single
set of software applications on the physical server. The client in effect,
has only "sub-letted" software resources controlled and maintained by someone
else!
In a true "Virtual Server" environment only the hardware is controlled and
maintained by the site administrators. The software (i.e. the web, ftp, and
pop services, as well as the smtp gateway) is completely autonomous and
affords the client complete flexibility, control, and
power over how his or her Internet services behave.
How is this accomplished? The root physical server is multiplexed or
"partitioned" into many Virtual Servers. Each Virtual Server can be
configured and customized at the discretion of the client. This solution,
developed and pioneered by iServer, is far superior to the simple "Virtual
Hosting" solution so many vendors offer on the Internet today. By choosing
iServer- you choose control, you choose flexibility, you choose
power.
Is
your web site currently being virtually hosted?
Chances are yes. Almost all Internet Presence Providers
only provide simple Virtual Hosting solutions for their clients.
As you review the chart below, compare the capabilities of your
current web site to those of an iServer Virtual Server System.
If you find that your current hosting solution has less "YES's"
than "NO's", you are using a solution inferior to what you would
enjoy as an iServer client.

Virtual Servers
vs. Virtual Hosting - A Technical Perspective
iServer's unique Virtual Server is created by multiplexing a single dedicated
server into a system of multiple virtual machines. Each virtual machine, or
Virtual Server, is given its own IP address, domain name, web server with
complete logs and configuration files, ftp server, pop server, and smtp gateway.
In addition to the performance and flexibility of our Virtual Servers, our
Virtual Servers also offer virtual "hosting" capabilities. In other words,
virtual "hosting" is a feature of iServer's Virtual Servers. Our Virtual Servers
allow you to create virtual web hosts, virtual e-mail, virtual ftp logins, and
quota support. Most of our competitors simply offer virtual hosting, which is
simply a single
feature of our Virtual Servers.
A real Virtual Server is not simply a virtually hosted (VirtualHost) site on
a web server we control, rather we give you "virtual root" access. When you
telnet to your Virtual Server you will see directories such as "dev", "usr",
"bin", "etc". In your "etc" directory you will find your own "passwd",
"aliases", and "sendmail.cf" file- this allows you unlimited flexibility to add
as many POP accounts, aliases, autoresponders as you would like.
With our Virtual Servers you will also find an entire "usr/local/etc/httpd"
directory structure including your own httpd.conf, srm.conf, and access.conf
files, your own logs, and cgi-bin. Basically our Virtual Server acts and
behaves like a dedicated server, you have complete control of your web, ftp,
and e-mail services. The basic differences between a dedicated server and
an iServer Virtual Server is the disk space and the price.
