sitecore Scaling Implement remote events in load-balanced enviornment

Example

If Sitecore is setup in a CM-CD enviornment there could be a need to fire events on CD server when CM events are fired.

The example could be firing publish:end:remote on CD when content editors done publish on CM.

In order to make sure that events are firing the following steps are required to be done:

1. Check that event queues are enabled in web.config

    <!--  ENABLE EVENT QUEUES
            If enabled, Sitecore sends local events to the event queue available to remote instances,
            and handles events in the queue from remote instances.
            Default value: true
      -->
      <setting name="EnableEventQueues" value="true" />

2. Add ScalabilitySettings.config to each instance. Set InstanceName for each server and PublishingInstance to the CM server instance name.

The example of ScalabilitySettings.config could be found in the App_Config/Include folder.

<!--  INSTANCE NAME
            Unique name for Sitecore instance.
            Default value: (machine name and IIS site name)
      -->
      <setting name="InstanceName">
        <patch:attribute name="value">BAYERUATCD</patch:attribute>
      </setting>
      <!--  PUBLISHING INSTANCE
            Assigns the instance name of dedicated Sitecore installation for publishing operations.
            When empty, all publishing operations are performed on the local installation of Sitecore.
            Default vaue: (empty)
      -->
      <setting name="Publishing.PublishingInstance">
        <patch:attribute name="value">BAYERUATCM</patch:attribute>
      </setting>
      <!--  COUNTERS INSTANCE NAME
            Instance name for performance counters.
            Default value: (value of InstanceName setting)
      -->
      <setting name="Counters.InstanceName">
        <patch:attribute name="value">BAYERUATCD</patch:attribute>
      </setting>
      <!--  SECURITY CACHE EXPIRATION
            Sets the absolute expiration on the cached security data.
            A value of 00:00:00 disables automatic expiration of security caches.
