When looking at converting to Hybrid Cloud Observability and comparing it to our current configuration. I have been told the amount of devices/elements increases per poller substantially.
If this is true is it possible to decrease the number of needed additional pollers based on the increased in efficiency?
Is there somewhere we can see the changes in poller capacity with Hybrid Cloud Observability?
Looking at the requirements page.... https://documentation.solarwinds.com/en/success_center/orionplatform/content/core-orion-requirements-sw1916.htm#Cloud 
In these requirements it only mentions the 50 user limit and the 12000 element limit for "on premises" installs. So there could be quite a saving there if you can afford the cloud costs. You will save on pollers and spend on cloud compute costs.
