For us, our Nomad cluster clients (the instances that runs the workloads), are a bit more ephemeral, the workloads are moved around servers, and the servers go up and down as we scale the infrastructure.
A database, that should be highly available, that is on a node that's going down, might disrupt database clients and end-users.
Not to say that you can't host databases inside the cluster, you can place databases on more stable servers (tag them with "db", be careful when you make changes) and don't move workloads, or manage expectations with the database clients.
