Web Farms

A web farm is a group or cluster of servers that act like a single web server. CA APM supports multiple servers for the application and web server components. Using a web farm provides the following benefits:

Improved performance. More than one server is available to handle network requests.
Scalability. More servers can be added to handle additional users and requests.
Backup. As each server duplicates the resources of the others, a backup server handles network requests if one server fails or shuts down.

You can use CA APM in a web farm. However, you install and configure the software that controls the web farm because CA Technologies does not provide this software. The custom installation sets up the multiple web and application servers in the configuration that enables you to set up the Network Load Balancer that you select.
