Related services above doesn't refer to plugins but to other non-node related infrastructure type projects. I just realized I didn't specify what they were running on (they are not part of API or Seed).

The main node (API + Hivemind) doesn't need 128 GB and can be done with 48 GB. You may go with 128 GB but that would be overprovisioning. Definitely a good idea to launch out of Asia.
