Elastic's on prem support amounts to little more than an onsite where they explain to you how the Java Garbage Collector works. EVERY detail about tuning your clusters derives from keeping the Java GC from ruining your day.

There's some index template optimizations but any semi-competent engineer or dba should be able to figure all that out (it's literally all in the documentation about what not to do).

You'll still be able to pay a consultant to come help you -- they don't have to be from Elastic.

In fact, it seems like Amazon just created an industry for third party consultants here.
