SafeKit Solutions on Windows and Linux with Application Modules

How the cluster configuration works with application modules?

Simplicity of cluster configuration

With the SafeKit software, cluster configuration for a critical application is simple. You must configure either a farm application module or a mirror application module according the high availability architecture suited for your critical application.

Application modules

Cluster configuration involves writing an application module which includes:

1. the application stop and start scripts,
2. the configuration file userconfig.xml which contains:
   • names or physical IP addresses of the servers,
   • name or virtual IP address of the cluster,
   • file directories to replicate in real time between 2 servers for a mirror module,
   • network load balancing criteria between N servers for a farm module,
   • configuration of software and hardware failures detectors.

Simplicity of software cluster deployment

Once the application module is configured and tested, deployment of the HA software cluster requires no specific IT skills:

1. install application on 2 standard Windows or Linux servers,
2. install the SafeKit software on both servers,
3. install the application module on both servers,
4. configure the new names (or IP addresses) of the servers and the new name (or virtual IP address) of the cluster ,
5. start the cluster.

Configuration is somplified thanks to a web console.
