Help with sizing

This is my current set up.

How does licensing work if I want to go with platinum or enterprise license?

Current ELK Setup:

Elasticsearch: 3 nodes
Logstash:1 node
Kibana:1 node

ELK stack deployed Docker containers. The VM is 32 GB RAM

For platinum, would I need 5 nodes, meaning 5 platinum license? (should logstash and kibana be factored in?)

For enterprise, is it enough if I get ERU for my ES nodes (so 3 ERUs) or do I need ERUs for kibana and logstash too . Please help

You should contact the sales team for that.
For the 1st question (platinum), only Elasticsearch nodes are counted AFAIK.

For the second one (enterprise), I honestly don't know.

But to me, enterprise is the best one as it includes everything possible! :wink:
