in most cases elastic is easier to scale than a relational or timeseries db

I mean, kind of? It depends on what your data looks like and how you're querying it.

If you're not doing free-text search, and your data will fit in memory in a big relational database VM for the foreseeable future, why Elasticsearch?

sure relational db is ok if fits in memory, but if we're talking about TBs of metrics i'd rather look for another way
