1. SSP Capacity Planning

2. One powerful machine with everything

3. Apache on one machine load balancing SSP/Tomcat on smaller boxes Apache Database Other Backend Systems Tomcat/SSP

4. External cookie-based load balancer with Apache/Tomcat on smaller boxes Load Balancer/ SSL Encryption Engine Database Other Backend Systems Apache/ Tomcat/SSP

5. Hardware Chart Can be pricey $10k – $50k Apache’s load balancing is limited Performing SSL with Apache will ramp up the CPU cycles Cost Can not scale Cons Same as with Apache but scaling is better. Adding in SSL won’t necessarily degrade performance Can add more boxes easily Portal computers are relatively inexpensive Easy to manage Pros Dedicated load balancer Apache load balancing One Powerful Machine
