There are multiple ways to cluster EJBCA and the following sections provide information on clustering the local Galera nodes with each other. 

Note that as of EJBCA Cloud 2.0, the preferred way to cluster EJBCA is clustering with an RDS database. Using the configuration wizard, you can directly install into an RDS database, allowing you to point nodes to this new centralized database and load balance between them.
