Throwing out a clarification: EVcache is effectively a complex memcached client + an internal ecosystem at Netflix. You can get much of its benefits with other systems (such as the memcached internal proxy: https://docs.memcached.org/features/proxy/).

For plugging into other apps they may only need a small slice of EVCache; just the fetch from local-then-far, copy sets to multiple zones, etc. A greenfield client with the same backing store could be trivial to do.

That all said I wouldn't advise people copy their method of expanding cache clusters: it's possible to add or remove one instance at a time without rebuilding and re-warming the whole thing.
