I'm sure you'll further improve this, good luck! The single deployable server you advocate is a single point of failure. I'm not talking about a deployable server, I'm talking about a deployable as a unit of deployment, e.g. a war archive. A deployable is a compile time artefact, a single point of failure is a runtime concept. In that sense, saying a deployable was a single point of failure is like saying a line of code is a single point of failure.
