Concluding Remarks
There are several factors that should be considered when establishing your enterprise data center architecture. Many of these factors are determined based on business needs and standard IT operating procedures.

The primary focus for Esri system architecture design services is to identify hardware and infrastructure resources that satisfy user productivity needs during peak GIS system loads. This effort focuses on the primary production hardware and available network infrastructure bandwidth required to support GIS operations.



Other factors contribute to the final system configuration. These factors include provisions for system maintenance, updates, configuration control, software licensing, and security. System requirements often include hardware provisions for application development, system test, production staging, background processing (i.e. map cache maintenance and replication services), system backup, and security. System migration will normally include continued support for legacy operations while introducing new technology, often on separate hardware environments.

The CPT Design tab provides a framework for modeling enterprise operations. Figure A-7.38 provides an overview of the adaptive CPT Design platform module.
 * Up to 10 unique platform tier available for software assignment
 * Each platform tier can scale to any required number of nodes (platforms)
 * A different platform technology can be selected for each tier.
 * Platform rollover setting automates platform sizing (fixed node option also available)
 * Selected hardware can be native (physical server) or Virtual Server platform tier
 * Platform names can be assigned to personalize the IT environment
 * Software components can be installed on any platform tier
 * Three additional Host platform tier are included at the bottom for Virtual Server platform assignment.

An Enterprise GIS design includes business, application, data, and technical architecture requirements. The Capacity Planning Tool provides a framework that models enterprise GIS performance and scalability, integrating the full range of Enterprise system design requirements into a solution that represents your GIS production needs.
