Why Use an ISP?• Most client organizations are anxious to go on the Internet

without questioning the reliability of the ISP that can accommodate their Web site

• There is more to deciding on an ISP than price:– Technology– Staffing– Speed– Amount of congestion

• Resources to host your own Web site:– Hardware - A Web server, communication gear, and a

special router: $5,000 to $18,000 a year• http://www.dell.com/content/products/category.aspx/servers?c=us&cs=04&l=en&s=bsd&~ck=anavml

– Communications - Typically a T1 or fractional T1 line:

$8,000 to $12,000 per year• http://www.speakeasy.net/business/

– Staff - At least a Webmaster, a Web designer, and a help desk: $45,000 to $80,000 per year

– Total - $58,000 to $110,000 per year

The Infrastructure of an ISP Provider• Your company Web site has to be stored on a

Web server that is always connected to the Internet by a high-speed link

• An ISP should provide:– Standby electric power as backup to keep the site

available in the event of a blackout.

– Redundant fault-tolerant servers to ensure that your Web site will continue in the event of a hard drive or a server breaks down.

– Redundant communications lines to keep your site active in the event a phone line or a router goes down

– One or more firewalls to protect your Web site from hackers or unauthorized access.

The Backbone of the Internet

• Backbone: a cluster of competing companies called network service providers.

• Service Level Agreement (SLA): a contract between the user and the ASP vendor stating the vendor’s commitments to ensure reliable delivery of information.– Limits of liability – Example: Service goes out for one day in a month?

• Refund 1/30 of monthly fee of service?

• Shaking hands is not enough.
