A three-tiered model introduced lightweight client software,
built-in load balancing, and a new storage area network
ƒ Rigorous cross-functional-area project management:
A new software configuration management process and indepth go-live rehearsals analyzed all potential outcomes

Next Steps: Future Enhancements
ƒ Out-of-area disaster recover plan:
Redundant data centers currently provide protection, with
automated failover mechanisms; a similar backup plan will
provide out-of-area coverage
ƒ Content caching:
The new storage area network provides a flexible architecture
for intelligently distributing content
ƒ Linux:
The open Oracle 11i platform can integrate emerging Linuxbased systems and applications, and cost-effective Intel-based
servers
