Which VPS is suitable for Elaatic Search?

Question

elasticsearch

Good afternoon. Tell me what characteristics (cars) VPS should have so that ES does not slow down.
I will attach a picture with an existing VPS, tell me if it was enough.

Answer 1

Elastic is quite memory hungry and in the recommended specifications it has at least 8 GB of RAM, and ideally all 64 GB.

Answer 2

If you want full-text search and save on hosting - you definitely do not need Elastic. Elastic is Java, it needs a lot of RAM to function properly.
Use SphinxSearch (or its Manticore clone) for full-text search - it eats much less (tens of times) with exactly the same functionality. And it works many times faster than ElasticSearch.
Of the minuses of Sphinx compared to ElasticSearch - there is no cluster (sharing the index between several servers), that is, each server is independent. But if you have everything on 1 server, then it does not matter.
Why ivi moved from Sphinx to Elasticsearch Because they needed a cluster. At the same time, they lost in performance and needed to use more iron.

Answer 3

In test mode, elastic can be run on 512 (set 128/128 in the configuration file), but if in production, then 4 gigs is desirable, and more.
