Can an Automation Engine be operated on more than two servers?
and we said ...
The Automation Engine is based upon multi-server operation. The ability to have several Automation Engines in parallel operation offers more reliability and allows the setup of fully scalable AE systems able to grow along with performance requirements. The Automation Engine also supports the constant efficiency advancements of today's hardware systems increasingly being equipped with more processors.
The technical foundation of Automation Engines are the server processes wherein work and communication processes are distinguished. As the work and communication processes of an AE system are not limited to a single node/computer, both efficiency and reliability are boosted through the distribution of these processes over several computers.
Theoretically, you can activate an unlimited number of work and communication processes. By adding processes it is possible to adjust to growing strain on the AE system. Should a heavy workload exist due to the number of logged-on agents and UserInterfaces, the number of communication processes can be increased. Likewise, should the number of AE system tasks become too burdensome, the number of work processes can be increased. Licenses are required for each physical server and therefore do not depend on the number of processes.
