From OM 5.1.0 onwards, user can start ānā number of services of same type behind a load balancer (ex: NGINX) and they can replicate the service without any configuration needed in OM except changing port number in application.properties file. So, for instance, to scale orchestrator:
1/ Duplicate orchestrator directory under OM_HOME/roles. 2/ Change "server.port" property value in application.properties file for each new created instance. 3/ Start the instances.
Obviously, load balancer configuration should also be done to take into account the different instances.
