I've setup an ElasticSearch instance with 1 node + an app once already but now I'm about to setup a cluster.
What I'm thinking about is installing the entire ELK stack + x-pack using a basic Elastic license on ubuntu 18.04 LTS and then snapshotting and duplicating the VM into a cluster.
The reason why I'm posting this in the X-Pack section is because I'm wondering whether or not I need to install X-Pack. I might get a gold or platinum membership in the future and I like to future proof. Appart from the upgrade assistant, and future proofing what's th benefit of installing X-Pack ?
I can simply setup ELK on this base server then install X-Pack later when I need it right ?
