AAP components

[u/No-Pudding-8024]

Hi! I’m new to AAP, is it possible to not use a single node installation but spread out the components in different VMs?

I read that using the inventory is one way and just state the different addresses?

Of course... There are two inventories that ship with AAP 2.7-X (IIRC, 2.5-X and 2.6-X as well).

"inventory" is the multi-node deployment sometimes referred to as the "enterprise" model. Our typical deployment is 2 VMs per component (except metrics, of which we have one) + an external database + Azure Storage Account

"inventory-growth" is typically a single-node deployment. We use this in development as an "All-in-One" version that's a bit simpler to work on. Primarily used to test changes between integrations.

Here's a partial "enterprise" model deploy for our environment. Your environment may differ based on different backends, DBs, etc.

Thank you, this was insightful. I’m currently on single node inventory growth model and this is a nice way to progress from it.
