Co-located Hosting
You have decided that a dedicated server offers the best
features for your online presence. There is no need to share
resources and you can set up the server as you please. There
remains just one question: Are you going to rent or buy your
server? Dedicated hosting means that you are renting a server
from a web host. But you also have the option of buying your
own server and having the host provide the facilities to house
it and connect it to the Internet. This service is called
co-located hosting.
The advantages of colocating include all the advantages of
dedicated hosting, i.e. you have the resources of the entire
server and bandwidth to do with as you please. The additional
benefit over dedicated hosting is the lower cost. Because you
own the server, your monthly fees don't include charges for
hardware maintenance and upkeep. On the other hand, your
initial outlay will be larger because you have to buy the
server. If the server is good quality and remains in service
for a reasonable length of time, however, your overall costs
will be lower with co-location.
The cost of co-location depends on the amount of space your
server occupies. Data centers house servers in racks that in
turn are housed in cabinets. Cabinets are usually 40 rack units
in height, with each rack unit equal to 1.75'. The cases of
server computers are measured in rack heights – 1U = 1.75'.
Typical sizes for servers are 1U, 2U and 4U, so the physical
size of your server will determine how much the co-location
host will charge per month. Bandwidth is another factor
affecting price.
There are several options available when purchasing a server
and getting it to the co-location data center. If you live in
close proximity to the data center you could buy a server
locally and set it up at your own premises. Once it is setup
you can personally deliver it to the data center. Another
option is to buy the server from a mail order retailer and have
them deliver it directly to the data center. This is a good
option if you are not located near the data center. It saves
you the cost of shipping the server and the retailer will be
responsible if the server happens to be damaged in
transit. The disadvantage is that you have to set up the
server remotely through a web interface. The third option is to
buy the server direct from the host. Not all hosts are in the
business of selling servers, but those that do may offer
financing and setup assistance.
Co-location or Dedicated?
co-location puts you in charge of the hardware, but that
also means that you are responsible in the case of hardware
failure. If you have signed up for dedicated hosting you are
renting the server, so the host will replace hard drives or
CPUs if they malfunction. The initial costs of co-location are
much higher than dedicated hosting. You have to buy the server
as well as insurance and software licences. All that is
included in a dedicated hosting plan. Hardware upgrades are
also more expensive with co-location because you have to buy
the new equipment outright and pay to have it installed.
Dedicated hosting plans usually allow you to upgrade either
hardware or bandwidth at a reasonable cost.
A co-location provider has to be chosen carefully. After
all, they will host both your hardware and your data. Points to
consider when choosing a co-location provider include:
- Security
- Network Redundancy
- Protection from Fire and Earthquakes
- Backup generators in the case of power outages
