Interact components

You must install a single instance of the Interact design time environment. In the design time environment, you define events, interaction points, smart segments, and treatment rules. You can install multiple Interact runtime servers to present offers to the customers.

Before you install the Interact design time environment, you must install and configure Campaign and an associated instance of Marketing Platform.

Before you install the Interact runtime environment, you must install a separate instance of Marketing Platform. A runtime environment must have an instance of Marketing Platform and at least one instance of the Interact runtime server. You can configure multiple instances of the Interact runtime server to work in the same runtime environment.

For best performance, install a runtime server on its own workstation, where no other IBM® EMM products are installed.

The following table describes the components that you can select when you install Interact:

Interact components
Component	Description
Interact Runtime Environment	The Interact runtime server. You can integrate Interact runtime servers with a touchpoint, such as a website, to present offers that are based on real-time data. You can install multiple runtime servers in your environment and organize them into server groups. Each server group must have one instance of Marketing Platform that must be separate from the Marketing Platform for Campaign and separate from other server groups.
Interact Design Time Environment	The design time environment for Interact. You must install the design time environment on the same computer as Campaign. You must install only one design time environment.
Interact Extreme Scale Server	Install the Interact Extreme Scale Server component, if you want to improve the performance of the Interact runtime environment. The Interact runtime environment uses IBM® WebSphere® eXtreme Scale caching to enhance performance. If you want to install the Interact Extreme Scale Server component, you must install it for every instance of runtime server that you install. For more information, see the IBM® Interact Tuning Guide.
