It&#x27;s not a problem &#x2F; wrong to put unrelated things in a single cluster (and just because they&#x27;re not talking today, also doesn&#x27;t mean they won&#x27;t in the future).  But if you really want hard separation between them, you could easily have separate clusters.  It&#x27;s a lot like a directory with files, if you put everything in one directory things like the output of ls have some noise in them, but if you&#x27;re used to searching (service discovery) then it doesn&#x27;t matter too much.<p>Disclaimer: I work on Compute Engine (and I&#x27;ve always just used a single cluster)
