Web hosts place your web site on a
computer or server that is directly connected to the Internet where
those surfing the web can access your site.
When looking for a web host, it is
important to not only know what your needs are now, but also what they
could be once your business grows as it much easier to remain with one
host and upgrade than it is to completely move your site to another
host.
However, many of these terms can be
confusing and knowing what you need, or how much of it can be
difficult to determine.
SIZE
The rule of thumb is that a page of
text with one or two images will take up about 33K. That size means
that 1 GB of data transfer would mean 30,000 page views per month, 2
GB 60,000, etc.
A small site expecting somewhat light
traffic can have its needs met with 10 to 100 MB of disk space and 1-5
GB of data transfer per month.
While text takes almost no space at
all, movies, graphics and sound files eat up space and bandwidth. If
the site has lots of these items, 20 to 40 MB will be needed.
Commercial sites could need 50 MB or
more with 5 to 30 GB depending on the expected traffic.
Ensure the web host you choose can not
only meet your needs now, but also when your business grows by
supporting upgrades in space and bandwidth as well as offer a
dedicated server should you need.
Ask for a few representative web sites
they host so you can see if they are a comparable size to yours as the
needs of a small site are not always the same as a large one. This
also allows you to check the network speed.
SPEED
As a rule of thumb, a T1 line can
transfer 1.5 MB per second while a T3 line can transfer 45 MB per
second. There are also OC or Optical Carriers. However, besides speed,
hosts should aim to use less than 50 per cent of the available
bandwidth as overburdening network connections will result in slower
performance. That means a T1 with light traffic can be faster than a
T3 with too much traffic.
Make sure to ask about capacity and
usage. A good host should have enough space and bandwidth for some
growth and the ability to get more as needed.

SERVERS and APPLICATIONS
While the average personal computer can
host web sites, high-speed SCSI disk drivers, error-correcting RAM and
powerful microprocessors will result in more responsive web sites.
Dedicated servers are needed for
high-traffic sites, or where there?s a need for strong security or
customized software.
As your business grows and your needs
change, you may need to change platforms, so ensure the host not only
offers them, but can also back them up with technical support.
Most servers run on either Unix (Linux)
or Microsoft Windows NT platforms.
Unix is the traditional operating
system of web servers and are extremely reliable and stable and less
expensive. Most CGI scripts were written to be used on a Unix machine
and may need modifications to be run on an NT machine.
Microsoft developed NT so it works well
with many Windows applications. That?s important for those working
with an MS Access database.
While you do not need an NT server if
you built your web site using MS FrontPage, you will need to ensure
the host has the FrontPage extensions installed on their server.
Also ask the host if everything is
already in place for you to run a database, e-commerce solutions,
shopping cart or secure online payment system, CGI scripts, mailing
lists, web statistics, and other applications you need for your site
before you sign up.
RELIABILITY
There is no use in having a web site if
it is always down. Look for a guarantee that the system will be up 99
per cent of the time. This can be guaranteed with automatic monitoring
equipment, experienced engineers who can anticipate problems and
redundant back-up systems. Keep in mind that each per cent of possible
downtime is more than 100 minutes of possible down time each week. Ask
about hardware use, connections and safeguards.
Also ask if the web host has reliable
security features such as firewalls, built in redundancy and daily
backups.
SUPPORT
It is important to get the type of
support you need, when you need it. While e-mail support works fine in
most cases, be wary if no phone numbers are available in case of an
emergency when you need to talk to somebody directly. Keep in mind
that restricted hours of phone support can also be a problem.
Send an e-mail inquiry or call asking a
few questions you might ask if and when you do set up with them to
ensure they can speak to your needs and experience level. Try this at
different times of the day and week to get a feel for the response
time. However, keep in mind that some hosts answer sales questions
faster than technical questions.
Also browse through the FAQ (frequently
asked questions) section to determine if the host is familiar with the
industry-associated problems and can speak a language you can
understand.
PRICE
When looking at prices, keep in mind
that "You get what you pay for" and "If it sounds too
good to be true, it probably is."
There are free sites available, but
many require you display banner advertising in return slowing down
your site, drawing your traffic to their advertisers and often provide
unreliable technical support.
Also, make sure you are "comparing
apples with apples." Data storage is easy to supply and is
therefore cheaper, whereas uninterrupted, high-speed access is
difficult and more expensive as is quality customer service, technical
support and guaranteed uptime.
Most web hosting companies offer
monthly, quarterly and/or yearly payment options, so make sure to ask
about minimum commitment period and cancellation policies.
Look at the flexibility of different
packages to ensure you pay for only what you need now and also make
sure your provider will be able to handle your needs when your
business grows and you need to upgrade.
ONCE YOU KNOW YOUR NEEDS
After determining your needs, find a
few hosts that fit the bill, go to their sites to get a feel for their
professionalism, check out some of their customers and test customer
service. Word of mouth is the best advertising as it?s the most
truthful, but remember not every web sites? needs are the same, so
make sure you talk with those which are similar in size and needs as
yours.
If you are not certain, ask about
cancellation policies and ensure there is a 30-day money-back
guarantee.
