   Each of the MySQL server instances in a group can run on an
      independent physical host machine, which is the recommended way to
      deploy Group Replication. This section explains how to create a
      replication group with three MySQL Server instances, each running
      on a different host machine. See
   <a class="xref" href="group-replication-deploying-locally.html" title="20.2.2 Deploying Group Replication Locally">
    Section 20.2.2, “Deploying Group Replication Locally”
   </a>
   for
      information about deploying multiple MySQL server instances
      running Group Replication on the same host machine, for example
      for testing purposes.

   This tutorial explains how to get and deploy MySQL Server with the
      Group Replication plugin, how to configure each server instance
      before creating a group, and how to use Performance Schema
      monitoring to verify that everything is working correctly.
