About ClusterCATS for ColdFusion  
 
 

ClusterCATS for ColdFusion is a Web server clustering technology that provides load balancing, fail-over and other services to assure high availability for the ColdFusion Application Server (CFAS). ClusterCATS allows you to cluster distributed Windows NT or SUN Solaris Web servers into a single, high-performance, highly available environment of Web server resources.

A server cluster consists of two or more Web servers located on a LAN or across a WAN. Web servers included in a cluster operate as a single entity to provide rapid and reliable access to resources on those Web servers. A cluster can help your web site avoid the consequences of busy and failed servers, slow networks. With ClusterCATS you can avoid bandwidth, latency, and congestion problems.

 
 
  Rapid and reliable access  
 
 

A ClusterCATS cluster provides users with rapid and reliable access to content by directing HTTP requests to the optimum Web server in the cluster. ClusterCATS determines which server in a cluster should respond to a request by employing the following services:

  • Failover -- Providing alternate Web servers in the event of server overloading, or hardware and software failures.
  • Load balancing -- Balancing HTTP request load among a cluster of Web servers through HTTP redirection.
