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.
