Vendor Management / Outsource Web Infrastructure

Initially high dollar amount per server. Included backup, monitoring, and spare equipment

Service Oriented Solution

Risk mitigation contrasted by high cost.

More Traffic!

Add 4-6 servers. Add better load balancing. Add point to point T1 line between hosting

facility and office. Increase monitoring solution. Begin transition to J2EE platform with JRUN
