- What does "same physical resources as main instances" mean?
- Do they need to have the same CPU architecture (x86/AARCH)?
- Can one instance be Docker based, another native on on-prem, and another one in the cloud?
from documentation.
Same physical resources as main refers to CPU and memory. This is most important/necessary to get across, some assumptions created mismatched expectation w/potential customer because they had an assumption that they could "save" on replicas.
As to no 2. and 3., in theory it could work, but does depend on the compatibility of architectures so should be tested and we don't actually recommend/guarantee.
Tagging @gitbuda to raise flags if I wrote something incorrect.

@Ana-Marija-design and @gitbuda I need more clarification for "Same physical resources as main refers to CPU and memory.". Does this mean that machines must use two identical CPUs and the same amount of RAM? By identical CPU, I mean the same manufacturer and model.
from documentation.
The same amount of RAM = hard yes.
CPUs = Not such a hard yes. Quite possibly different ones could/would work, but we don't really check this and can't guarantee it.
At the very least, each replica can become a main and will need the same resources to run smoothly. @gitbuda correct me if I've not stated the CPU issue well.
from documentation.
I've added the callout to the docs. Once we will have some more details we can update the docs one more time.
