A free Highly Availabile Database

The code for this post is available on GitHub

With the release of RavenDb4 and in combination with their Community License and Ubuntu Server Edition it is now possible to deploy a highly available database setup that is free of software licensing costs (server hosting costs obviously still apply)

To demonstrate a possible setup clone my vagrant-ravendb, navigate to the root folder and run

vagrant up

This will reproduce the network shown below: (as an aside, if you haven't already checked out vagrant[1] i highly recommend doing so)

Once the VM's are running you will be able to connect to the RavenDb instances via the studio and perform the final setup of the cluster.
