   MySQL Group Replication is provided as a plugin for the MySQL
    server; each server in a group requires configuration and
    installation of the plugin. This section provides a detailed
    tutorial with the steps required to create a replication group with
    at least three members.

    To deploy multiple instances of MySQL, you can use
    <a class="ulink" href="/doc/mysql-shell/8.4/en/mysql-innodb-cluster.html" target="_top">
     InnoDB Cluster
    </a>
    which enables you to easily administer a group of MySQL server instances in
    <a class="ulink" href="/doc/mysql-shell/8.4/en/" target="_top">
     MySQL Shell
    </a>
    . InnoDB Cluster wraps MySQL Group Replication in a programmatic environment that enables you easily deploy a cluster of MySQL instances to achieve high availability. In addition, InnoDB Cluster interfaces seamlessly with
    <a class="ulink" href="/doc/mysql-router/8.4/en/" target="_top">
     MySQL Router
    </a>
    , which enables your applications to connect to the cluster without writing your own failover process. For similar use cases that do not require high availability, however, you can use
    <a class="ulink" href="/doc/mysql-shell/8.4/en/mysql-innodb-replicaset.html" target="_top">
     InnoDB ReplicaSet
    </a>
    . Installation instructions for MySQL Shell can be found
    <a class="ulink" href="/doc/mysql-shell/8.4/en/mysql-shell-install.html" target="_top">
