The Case for Outsourcing

• Companies need ever more networked applications
  and services
• Installation, maintenance, management
• Worse most small companies dont have either
  resources or expertise
• Besides, would prefer to focus on core competence
• But isnt renting too expensive?

The Wheel of Reincarnation

ISPs Must Support Outsourcing

• If an ISP charges primarilyfor bandwidth
• differentiation?
• price war
• zero margin
• fickle customers
• How to lock in customers?
• Provide value added services
• But current infrastructure cannot economically
  offer value added services

14
E-commerce as a Value Add

• Two years ago companies were looking for simple
  shared or dedicated Web sites. Now they are
  creating mission-critical applications to support
  online commerce or intranet/extranet
  communities,
