	In simple single-server AppBoard configurations it is recommended to use the built-in, in-~~memory~~, H2 configuration database. However, in cluster configurations the configuration needs to be shared and kept in sync across two or more nodes so an external configuration database is required.

However, in cluster configurations the configuration needs to be shared and kept in sync across two or more nodes so an external configuration database is required. Setting up an external database for redundancy operation has two main steps:

	# Configure AppBoard to use an external database (versus the build-in H2).
