Scalability Requirements

As mentioned in Capacity Requirements, the SunWeb user base is expected to grow. The architecture for SunWeb's Java ES deployment must allow for horizontal scalability (adding more computers to the system as user activity increases). To meet this requirement, the SunWeb 4.0 architecture allows for more portal servers or gateways to be added at a later time to handle the extra load. For more information about scalability strategies, see Planning for Scalability in the SunWeb Architecture.
