Web hosts ultimately provide the same
service. An individual or a business places
a page on the host's server and people
all over the world can access that page
from their Web browser. But that, unfortunately,
isn't all there is to it.
A Web site's performance depends on the
bandwidth, server resources and infrastructure
of the hosting provider. Hosting comes
in many forms--shared hosting, dedicated
hosting and co-location, plus hundreds
of variations of each.
RELIABILITY
When
choosing a Web host, you should look for
size, speed, and diversity of dedicated
Internet connections, as well as what
hardware and software the host uses. Reliability
is very important. Is there more uptime
than downtime? Also important are a host's
response times. The quality and standard
of back-up power is also important, as
is security. But one of the most important
issues you'll face when choosing a host
is the quality and level of customer service.
CUSTOMER
SERVICE
Twenty-four-hour
customer service means next to nothing
unless the persons fielding calls are
qualified computer professionals. What
about the skill level of the technical
representative at 4 a.m.? How accessible
is an engineer during "non-business"
hours? Can the engineer on call be notified
via pager that there's a problem? This
isn't a problem if your site is simple
but can be if it's more complex.
RESPONSE
TIME
Response
time is important. When sending a message
out into the great unknown, it's nice
to get a response back within an hour
or two. This is something you can test
before signing on with a service. After
sending the host's support department
a question, how long does it take for
them to respond? Also, how helpful is
the response? If a host has extensive
online FAQs, then its customer support
team should respond faster to queries
and respond in more detail than if they
were bogged down all day telling 500 people
how to upload a page.
ENSURE
MAXIMUM UPTIME
Size
and speed indicate the Web host's total
bandwidth to the Internet and, therefore,
directly relate to the speed of a site's
delivery and the traffic it can support.
One of the most overlooked issues is diversity
of a host's Internet connections. To ensure
maximum uptime, it should have connections
to several national backbones. This ensures
that it will have at least one active
connection even if one of the national
backbones goes down.
Many
hosts claim they have "unlimited
bandwidth." This simply can't be
true, as no one has unlimited bandwidth,
and someone eventually has to pay for
it. If you set up a site which chokes
a host's Internet connection, the host
will either make you pay more or simply
shut off your site.
HOW
IS THE HOST SETUP POWERED?
What
hardware is being used, what operating
systems and Web servers are being run,
and what is its internal networking structure
like? After obtaining this information
from several different hosts, you'll be
able to sift out those with weaker setups.
What
about the physical platforms that are
used to host sites and connect to the
Internet? What about router platforms?
Are they redundant and diverse? At what
capacity do they implement upgrades? Are
the platforms made up of industry standard
vendors such as Cisco Systems, Sun Microsystems,
etc., or does the host use lesser-known
vendors or possibly other proprietary
methods? Also, is the host Y2K compliant?
All of these capabilities ensure interoperability,
especially between client and vendor in
private business applications where employees
have access to databases through the company
Web site.
Every
time a visitor goes to a Web site, he
or she downloads the images off of its
host's server and onto a PC. This transfer
causes data to be sent over the host's
internet connection, which is only of
a finite size. Too much data can cause
the connection to become clogged. But
figuring out your site's requirements
is easy. If your homepage has two 5K images
on it and receives 100 visitors, that
means that each visitor would download
10K of information over the host's Internet
connection or 10K x 100 or 1000K, which
equals 1MB. One to two gigabytes of traffic
is ample for 99 percent of the sites on
the Internet.
HOST RELIABILITY
Reliability
can be a tough issue. Servers crashthat's
simply a fact of life. Everyone has seen
the dreaded "Server not responding..."
message. For a host to admit to downtime
is an admission of failure. However, a
responsible host should understand that
crashes are a part of running a server
and be open about any major interruptions
of service. Your site should be reachable
98 percent of the time.
WHAT ABOUT DANGER FROM FLOOD?
You
probably won't ask what floor the hosting
facility is located on until there's a
flood. Business people and Web developers
often don't look at the Internet as something
physical. But the virtual world exists
on physical facilities, and competitive
pricing is only one of the critical elements
to consider.
HOW SECURE IS YOUR HOST?
Even
more important is the security of the
network. What is the host's security policy
and configuration? Do they have a firewall?
Is there a security expert on staff? Hosts
with weak network security are vulnerable
to hackers.
After
checking off the above items, you should
contact some of the host's current customers
to see how satisfied they are with its
service.
