The currently available Hedera instance sits on top of JGroups and Appia. Hedera is also available a preliminary implementation that uses Spread. Hedera is the continuation of the Tribe project.

Hedera is targeted at reliable group communication within clusters. In such environments, we expect group memberships to be relatively stable and group sizes to be moderate (at most a few hundreds). However, we expect a potentially large number of logical groups.
