CPT Composite Workflow load generation
CPT Desktop workflows accessing an ArcGIS for Server feature service must first be configured as a composite workflow on the CPT Workflow tab. Figure A-7.8.1 shows how to generate the workflow service times for the CitrixFeature composite workflow.

You can combine any group of Project Workflows or Standard Workflows into a single composite workflow using the Composite Workflow Analysis section located on the Workflow tab.

The DeskFeature workflow includes a combination of the following standard workflows:
 * AGD103 Wkstn MXD V 100%Dyn Lite 19x10 ICA
 * AGS103 REST MSD V 20%Dyn Med 13x7 Feature +$$

the CitrixFeature workflow includes a combination of the following standard workflows:
 * AGD103 Citrix MXD V 100%Dyn Lite 19x10 ICA
 * AGS103 REST MSD V 20%Dyn Med 13x7 Feature +$$

Select the workflows in the Composite Workflow Recipe section and identify the workflow recipe in column B (identify the percentage of the time each workflow will be included in the workflow display). The composite loads analysis will be included in the blue composite workflow transfer section. You can then use the results of the Composite Workflow Analysis to include the combined workflow values as one of your Project Workflows.
 * Copying any existing Project or Standard workflow and "insert copied cells" to create a template workflow in your Project Workflow section.
 * Copy the Composite Workflow Analysis blue cells (column A through column M)
 * Select the first cell in the template workflow row and "Paste special values" to insert new composite workflow.
 * Rename new composite workflow in Column A.
 * Update new composite "Workflow Description" in column AB.

The following ArcGIS for Desktop workflow architecture patterns are supported on the CPT Design tab.
 * Workstation.
 * Virtual Application Sessions Physical server.
 * Virtual Application Sessions on Virtual servers.
 * High availability (HA) Virtual Application Sessions on Virtual Servers.
 * Virtual Desktop Infrastructure.

CPT Design ArcGIS for Server platform configurations
The CPT Design tab provides the capability to represent a complete data center configuration supporting any number of Enterprise workflows from different user locations. ArcGIS for Server recommended platform configuration strategies will be provided for single-tier, two-tier, and three-tier configuration alternatives identified above. Five ArcGIS for Server workflows will be used to represent the user requirements in the CPT Design examples.

CPT Design ArcGIS for Server two-tier platform configuration
The two tier software configuration would normally host the Web and GIS Server on one platform tier, and the DBMS servers on separate platform tier.

The CPT Design workflows include three different data sources, one being an SDE Geodatabase (SDEGDB), the second a tabular business database management system (DBMS), and the third a file data source. Each data source will be represented on a dedicated platform tier for modeling purposes. The file data source is represented in the bottom row and platform sizing is based on network interface bandwidth requirements. Column A identifies the different user workflows:
 * Row 6 AGS File: ArcGIS REST service with file geodatabase data source.

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-7.33 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.
