Capacity Planning

Suggested Capacity Planning Methods

Here are some guidelines for capacity planning for a marketing site that does not already have a large customer base:

1. Put the initial Web server on a medium-size platform.
2. Examine the IIS 5.0 performance logs to determine how heavily the server’s resources are loaded by incoming traffic.
3. Examine the IIS 5.0 server logs to determine the number of customer visits the site experienced.
4. Using the results of steps 2 and 3, plot out the growth metrics of the site, with special emphasis on periods when the site was being marketed heavily or was more visible to Internet customers than usual (for example, just prior to a new product launch).
5. As the Web server’s resource utilization level reaches approximately 70 percent, use either content striping or specialization to add additional capacity to the site.
