Target Audience, Hosting and Business Issues
Recap ISP’s
Internet Service Providers (ISP’s) telecommunications companies that provide
home or business users with a connection to the Internet.
Organisations that provide Internet Services Must have a local Point of Presence (PoP) Charges and service vary considerably
Application Service Providers (ASP’s) Application Service providers (ASP’s) offer a
more complete service support than ISP’s.
ISP / ASP
Two reasons to have one Dial up to connect to the internet Web space, email, domain name etc.
Home users these are usually the same ISP Usually free (

Different services, different rates
What services?
Connection to The InternetEmail accounts (how many)Web Space (how much)Technical Help(free?)Fixed / varied IP AddressOther Items?
ISP Services
Charges Most are free these days, except for the cost of phone
calls. There are still a few like ClaraNET and Demon charging for a premium service or unmetred access.
Other way of paying in SurfTime or unmetred (pay a set fee each month – ‘AnyTime’)
ISP Services Cont
Performance Paid-for ISP’s generally okay Unmetred services can be variable depending on
time of day and number of users connected. Unmetred services failing to cope with large
numbers of users shortly after startup (BT, RedHotAnt)
Others having to restrict the rate at which users sign up (NTLworld staggered release of sign-up CD’s)
ISP Services (Cont)
User Support Support web pages are becoming more common
and more detailed, to answer the most frequently-asked questions.
Services charging monthly fees tend to offer local-rate/freephone support numbers (Demon, Clara, etc)
Free/unmetred services are using premium-rate numbers to subsidise the service (e.g. 50p a minute)
The quality of tech support can vary widely BT have been slated with BT Anytime
See what I mean????
Internet Services (Cont)
Other facilities they offer such as web page space and support Most offer web space (between 5Mb and 50Mb) Basic services (restricted /cgi-bin access, and
logging if you’re very lucky). Dedicated games servers (Clara, Nildram, Demon) Web filtering for family usage (LineOne, AOL etc) Anti-spam protection Portal-type home pages etc.

Servers
Recap - Server and Client Side
Web Servers are used to store, manage and supply the information on the World Wide – Server Side
The front-end experience - workstation/phone/PDA/kiosk from which a user accesses a server is described as a client
How to set up a web server A server / Server Software / Operating system
http://www.serverwatch.com Any computer can be a server (the spec
depends on the software you will use) http://www.howstuffworks.com/web-server.htm
Connection to the internet IP Address / Domain Name Entry in Domain Name Server Or…Some ISP that will do the lot for you
Operating System..
WindowsUnixLinuxThe difference????..the price and what
you run on them….
Server Software
Runs on server. Examples include Personal Web Server (Windows 98) IIS (Windows NT/2000/XP/2003) Apache iPlanet Web Server Roxen Zeus
The difference… Can’t run .net on apache yet Usually run PHP on a non IIS server
You have the server..whats next??
Connection To The Internet..
IP Address… Usually done through an ISP Allocated in this country by
RIPE (www.ripe.net)
Next Stage…Domain Name
Something that tells the person reading who or what you are
Range From £1 to £5 million Usually done through an ISP Fee paid to ISP (varies) The ISP pay a fee to registering agency

Domain Name Server
DNS is the way that Internet domain names are located and translated into IP addresses.
Maintaining a central list of domain name/IP address correspondences is impractical, the lists of domain names and IP addresses are distributed throughout the Internet in a hierarchy of authority.
There is a DNS server within close proximity to your access provider that maps the domain names in your Internet requests or forwards them to other servers in the Internet.
Web Addresses for registries and related sites

Technical Issues For A Web Server Security
Web servers are a shop-front to any organisation, and very high-profile systems.
Web site defacement is a major problem, as is unauthorised access to data or misuse of the server itself.
http://www.w3.org/Security/Faq/ http://www.cert.org/
Reliability the machine will be public-facing, so you cannot afford to
be down for long, if at all. Backups
Technical Issues For A Web Server Bandwidth
Have you got enough to cope with expected traffic, can you buy more if it’s needed, and if it’s capped in any way, how much is excess usage bandwidth going to cost ?
Performance Are the machine and the software man enough for the
job in hand ? Can they be easily scaled up to cope with increased workloads ?
Management Issues For A Web Server Purchase Cost Running Cost Content Management
There’s no point having a web site if you’re not going to bother keeping it up to date.
Maintenance is neglected all too often, leading to “cobweb sites”.
Internet Ethics Is the material likely to cause offence in some jurisdictions
(remember, you may be targeting your material at one country, but be visible globally)
Yahoo French Auction selling Nazi memorabilia
Management Issues For A Web Server
Legal issues Copyright, intellectual property, libel, data protection,
privacy policies, security policies
Information leakage can you afford to risk certain data being exposed via
your web server ? This is especially a problem for sites wanting to run web site and intranet from a single machine – NOT recommended.
Staff Cost
Management Issues For A Web Server (Cont)
Especially Ownership Raising a web site can turn a political “turf war”
into a bloodbath unless handled properly. Responsibility for individual aspects of the site
(content management, page editing, provision of material etc) needs to be sorted out from day one.
This issue kills more web sites than any other management issue.

- 2000 50% USA & Canada, and 50% Overseas
- 2005 projection 80% of users will be non
America
- 2010 projected figures world wide are: 200m USA,
200m European, 500m Asia, 100m rest of the world
