Virtual Private Server (VPS) is a virtual
environment hosted on a node server with several other Virtual
Private Server (VPS). By having a Virtual Private Server (VPS)
you have your own server, more or less, and you can add programs
and features as you like within your own environment without
being at the mercy of other users. This can prove to be an
advantage for some resellers since they might require special
security settings which they’d never be able to get
set on a reseller account.
A Virtual Private Server (VPS) is perfect
for you, if you require a dedicated environment but are not
able to afford a dedicated server or if you have outgrown
your standard reseller account and have no choice but to upgrade
to a dedicated environment. If you are using a control panel
such as cPanel then you should be able to get all your data
and websites moved over without causing any downtime or hassle
to your customers.
Upgrading to a VPS From Shared Hosting
Environment
Shared Hosting
Shared hosting is an environment where several
websites are all hosted on one web server. Each website account
gets its own limited share of disk-space, bandwidth, email
accounts, FTP accounts, databases. No server administration,
security administration & other system tasks to be performed.
Its plug-and-play means you just buy an account & start
using it. This only caters to small websites or individual
users.
VPS Hosting
Virtual Private Server (VPS) Hosting is the
technology that separates one physical server into several
independent virtual servers parts, each isolated from the
other. Each Virtual Private Server (VPS) has its own set of
processes and resource management, and behaves exactly like
a stand-alone server. It allows you a larger amount of resources
available for use. You also get full administrator level root
access for your Linux / Windows Virtual Private Server (VPS)
respectively.
With the Virtual Private Server (VPS) Hosting,
you are under the control of all operations & processes
running on your server.
It is a perfect balance of a shared environment
and a completely independent hosting environment.
Do not cancel your existing account
till the time all the websites start resolving from the VPS.
Your data would be there for you, unless
you asked not to move the files. Once you have verified that
everything is correct, then you start off using your Virtual
Private Server (VPS).
You should ensure that you have the nameservers
in place. Depending on your Virtual Private Server (VPS) plan,
you are allotted a specific number of dedicated IP. You would
have to change the nameservers for your domain name in your
registrar account. Once all the websites have the correct
nameservers, you just have to go on adding more websites,
everything would be done.
The step-up is suitable, when you have to
take care of the administration tasks, which include System
processes (management), repairing the Virtual Private Server
(VPS), backing up data & storing it, Virtual Private Server
(VPS) re-installation, reboot & overall management. Basic
knowledge of the Linux / Windows would also be a plus point.
You may also install any application or software which is
compatible with Virtual Private Server (VPS).
There is also a difference between Guaranteed
RAM & Burstable RAM.
Guaranteed RAM is what you will always have
available for use on your Virtual Private Server (VPS). However,
you might have occasions where your Virtual Private Server
(VPS) would require more than the available quota of RAM for
the system processes & other applications to be functioning.
Burstable RAM is available on the server
node to be used whenever there is a short time requirement.
However, this is subject to the usage of other Virtual Private
Server (VPS) hosted on the node. Abundant amount of resources
are almost always available on each server node. But burstable
RAM is not something which would always be available. If your
Virtual Private Server (VPS) happens to use up the additional
RAM available on the main node, it would start hampering the
performance of other Virtual Private Server (VPS) too, hosted
on the same server.
Enabling Spell Checker in the Horde
Webmail
One of the many unique features about the
Horde Webmail is the Spell Checker Facility. However, the
use of the Spell Checker Facility, requires certain components
to be installed. To install the Spell Checker Facility of
the Horde Webmail, follow these instructions:
Login to your Linux box via SSH as root.
Install aspell by running the following
command:
yum -y install aspell aspell-en-gb
You just leave it to install. You shouldnt
need to make any changes to the Horde Webmail, as it should
automatically detect the ASPELL installation. |
