Building and e-commerce web site

• The system development life cycle
• Web server functionalities
• Choosing the web server software
• Choosing the hardware platform

Choosing the hardware

• Hardware platform refers to all the underlying
  computing equipment that the system uses to
  achieve its e-commerce functionality
• You need enough platform capacity to
• Meet peak demand
• Without wasting money

Analyze the demand

• Number of simultaneous users and their frequency
• Nature of customer requests

• Dynamic page generation and business logic (like
  shopping carts) are CPU intensive.
• Telecommunication link to the site

• Scale Horizontally add single processor servers
  and balance the load among them. Cost effective
  but you need more physical space.
• Improve processing architecture of the site a
  combination of the above plus splitting of
  workload
