Hello, just wanted to get an idea on recommended VM specs to deploy datahub for a POC

Hello, what is the goal of the POC ("proof of concept" I assume). If you'd like get familiar with the functionality of DataHub and experiment with it, I'd start running it locally following https://datahubproject.io/docs/quickstart. 0.12.1 in my local Docker setup consumes a little more than 5GB of memory.
