This document describes the specific problems of a large scale high-volume portal site (in this case a portal for a large international bank). By showing what is necessary to achieve a large scale high speed portal - both in architecture as well as implementation - it questions whether this effort is justified for all portal needs. It is not an introduction to Enterprise Portals. It assumes working knowledge of portals and associated technology.
