Basically, it's a highly configurable way to make sure data gets from A to B and/or C etc. while maintaining transparency, logging, and simplifying the design and maintenance of each step along the way. It'd be a great complement to existing apps/services to allow management and ingest to Cloudron apps of external data sources, moving/copying data between apps, etc. (though to be fair, the learning curve is steep - not quite a brick wall, but a bit of a mountain, to get at its power).

Already dockerized, can do LDAP SSO, and it's a full-on ASF project, so there's some staying power implied there.
