Hi, I guess I am catching up with things from a year ago!

My question is to Gruvin's comment:
"Most, if not all of the VMWare based "vCloud" offerings run their internal IP network behind NAT. (Each public IP is mapped one-to-one with an internal IP behind a NAT router. Believe it, or not.) cPanel, quite reasonably, cannot tolerate this somewhat bizarre yet prolific and new situation."
From what I understand I have gotten True Cloud Servers, and I am concerned about what he says, b/c there is a point where you either believe the Features and Benefits of technical specs that may be beyond our understanding, or ask about their features in forums like this:
Feature: Fault-Tolerant Advanced Storage System
Benefit: "Cloud Servers are stored on redundant iSCSI enterprise storage servers with advanced technologies that utilize high performance solid state drives to accelerate both read and write performance."
Not my words, the features described by my provider.
In truth, I am moving into "three new [to me] technologies" at the same time:
1) Using a VPS
2) Looking into updating to Cloud Linux (and now using cPanel/WHM with full root access)- unmanaged
3) Using what appears to be a true "Cloud Server" as a web host reseller
Oh, and I forgot, pretty soon I will be finally going with the WHMCS license (on my older non root level resellers, and master resellers)
That being said having studied the information out there on Host Bill and OnApp and Solusvm I am sure t be scratching my head quite a bit.
It seems that there is some significant aspect to "Cloud Deployment" that involves some newly developed abilities to "add" additional resources "as needed" and that the "Real Cloud Solutions" are these incredibly expensive options that seem to be low cost, because you only pay for what you "truly use" as in metered usage.
So, my question is, that if I go ahead and spend in the "range" that you really have to spend for an "Average" Cloud Server "lets say its gotta cost close to (if not more) than $100/month. Will I really be getting the benefits of a "True Cloud Server"- meaning that when properly provisioned:
With enough Ram, Storage, BackUP, and Bandwidth, and some sort of load balancing software (say Cloud Linux) will the amazing cloud features of: Terabytes of Bandwidth, along with One GigaByte upload Link Speed, and all those other great features, really be something that will make a difference?
Because, there is no doubt that right now the Cloud, is an expensive option.
