...Now it gets a bit and I need it for presence but it auto scales. I don't understand that part the geek does it. 

Virtual server resources (CPU, RAM, diskspace, etc) are allotments from a much bigger system[s].   The server is allowed to "burst" (exceed) allotments sometimes.  But if it becomes the "new normal" those allotments are expanded to fit the need.  And the billing is adjusted appropriately.

The service provider themselves might be virtual with no actual hardware.  They can rent resources from Amazon or Google and package them for sale to end users.  Strange days indeed.
