Elastic licensing in virtualised environments


I am a little unsure about the elastic.co licensing for running multiple elasticsearch instances on a single host - is the license per instance or per physical host? Also how is that affected by HA functionality like VM failover to another host say ?


It's per elasticsearch node. Per instance that is.

thanks dadoonet

So I am safe to assume that if the licensed ES instance is failed over to another host then the license goes with the instance.

As long as both nodes are not up at the same time, yes I guess.
But that sounds like a bad practice to me unless I don't understand what you meant.

yep only one node up at the same time

host fails so VM running ES is migrated to alternate host (in an N+1) scenario
