Clustering

A cluster is a group of servers (independent computer systems), working together as a unified computing resource. An iCore system can be distributed over multiple servers, forming a clustered iCore system.

There are two main reasons for creating a clustered system:

• Improving performance
  and/or
• increasing fault-tolerance and minimizing downtime.

An iCore system consists of one or more instances of the iCore Process Server (iCPS) as well as several external resources, such as:

• Microsoft SQL Server
• Microsoft Message Queueing
• File storage

It is possible to also cluster external resources, which is a good idea if you want to further improve the fault-tolerance of your integration solution.
