Hi Gail, To clarify, what's possible today is to run Journaling[1] and have multiple identical Fedoras. In such a setup, you have one "master" instance and one or more "follower" instances that writes to the master eventually get propagated to.
It is possible to use this for high availability with failover, and with load balancing for reads, but keep in mind that: - It requires a complete copy of your repository for each node - There is still only one node that can be written to at any given time - Handling the actual failover and load balancing mechanics at a higher level is completely up to the integrator. Part of the goal for Fedora 4.0 (still a ways out) is to modify how Fedora does object-level storage[2] so that it is more amenable to true horizontal scaling approaches, with multiple nodes that can handle writes and data distributed across multiple nodes (instead of completely duplicated across each). - Chris [1] https://wiki.duraspace.org/display/FEDORA35/Replication+and+Mirroring [2] https://wiki.duraspace.org/display/FCREPO/High+Level+Storage On Tue, Sep 13, 2011 at 1:45 PM, gail truman <truman.g...@gmail.com> wrote: > Hello, > I believe there is a way to federate instances of Fedora to scale out.
