The distributed model is a web-based applications whose components are distributed across the web tier, application tier, and data tier, and require a secure zone between its web servers and application servers. The following are the reasons for deploying CA Risk Authentication in a distributed model:
In a distributed-system deployment, CA Risk Authentication components are installed on different servers. This is done for security, performance, and to enable multiple applications for using the risk-evaluation functionality. For example, the most common deployment is to install CA Risk Authentication Server on one system and one or more web applications on additional systems.
To perform a distributed-system deployment, you must select the Custom installation option in the CA Risk Authentication installer.
