There isn't a cluster storage component if that's what you're looking for.
We (Epimorphics Ltd) run Fuseki clustered for fault tolerance and
multiple query request performance. The database is stil single
machine, but replicated. We simply run multiple machines and multiple
Fuseki instances, fronted by Apache httpd (controls the externally
visible URIs and routes to any static content) and a load balancer in
fron of that). The Fuseki instances aren't contactable directly from
the public side (port 3030 is blocked externally) - only httpd is on
ports 80 and 443.
(actually, we open port 3030 to specific machines sometimes for direct
update but it's still not available to the publicly facing web traffic.)
