Application Server

The TrueSight Capacity Optimization Application Server:

  • Provides the communication bus for all other TrueSight Capacity Optimization components
  • Supports all analytical, modeling, and reporting tasks
  • Provides the primary scheduler for executing TrueSight Capacity Optimization system tasks and connectors
  • Supports all presentation-related activities from the TrueSight Capacity Optimization Console

The following capabilities and constraints apply to the Application Server:
  • Multiple Application Server computers can be deployed in a TrueSight Capacity Optimization instance.
  • You must run the TrueSight Capacity Optimization installation on each Application Server computer.
  • You can select a subset of Application Server components in the installer’s custom screen.
  • One Application Server computer can have only one Application Server component of each type.
    For example, you cannot have two web server components on the same Application Server computer.
  • Most of the components can be replicated for scale-out, one on each Application Server computer. The only exception is the Data hub, which cannot be replicated.
