Scalability Requirements

Most organizations anticipate growth in their user populations and want to know that their portal service can grow along with the size of their user populations.

As a result, no computer system should be more than 80 percent utilized under daily peak load. Also the deployed system should accommodate long-term growth of 10 percent per year.

While there are upper limits to how much any system can scale, due to the increased interactions among its components and the limitations of the network infrastructure, the Portal Service on Application Server Cluster reference configuration is designed to be easily scalable up to these limits.
