Deployment Separation

The middle tier is separated into two middleware server deployments. One for client functionality and one for integration functionality. A default middle tier installation includes a single machine with two separated clusters one for each type of deployment - MainCluster exposing services used by interactive clients and IntCluster exposing integration services.

• Main Cluster – Used by interactive end users (client requests/activities)
• Integration Cluster – Used for integration services, background jobs, reporting.
• The two clusters will by default include one managed server each.
• One Node manager that controls all the servers.
• IFS EE ClickOnce download served by MainCluster as a separate client.war application, not the HTTP Server

The separation of the middle tier into two deployment give flexibility when sizing and planning installations. By separating client and integration functionality the end users are less vulnerable to high load peaks in integrations. After the default installation is setup with the IFS Installer it can easily be extended over more machines using the Admin Console. More information about the deployment separation architechure can be found on the sections IFS Middleware Server and Robustness Considerations.
