173. Distributed environments and database migrations

     Actors:

     • database server / cluster
     • load-balanced application servers relying on a database schema with migrations
     • reverse proxy

     Issue:

     • managing database schema migrations

     Possible sequence:

     • create the database
     • run a service that executes database schema migrations
     • start application servers
     • start the load-balancer / reverse-proxy
