Introduction
The basic concept of Cloud IT is a serverless office, all servers (domain controllers, file servers, mail servers, etc.) are virtualized in a datacenter with WAN Optimized connections. Why? Less expensive and more reliable.
This is not theoretical. My name is Rick Parker and I started Bedouin Networks in late 2006 to prove this would work. Bedouin's beta client was Gimundo.com and Gimundo ran on the Bedouin platform for about 14 months before being sold. The results were simply stunning, no downtime for any services, none, for the last 7 months. This is the way IT should be and can be. What I will be doing is explaining how this was done and what can be done to improve the concept and design by suggesting and requesting feedback from others.
Some of the Vendors on the right I am sure you have heard of, others probably not, but they were selected primarily through experience but a few out of sheer interest. This is one of those circumstances where the whole is exponentially more important then the parts. The list is a Cloud IT Stack made up of the primary components, Datacenter, WAN Optimization, Virtualization, Monitoring, etc. some components may be swapped out but one of each is required.
The othe key concepts are the Virtual Private Cloud and RAID to the next level, The Redundant Array of Inexpensive Datacenters
First Question, What is the problem with virtualizing a router?

Hint, What is generally considered unique to a router configuration and what router feature do you need to get support for more then one of them?

The answer is the default gateway.
The problem is if the cloud has multiple projects or clients that you would like different external IP address ranges for you need multiple
default gateways. This requires source based routing that is some routers support better then others. Foundry does SBR in hardware so there is little to no CPU / Resource impact by SBR. The Foundry MLX also has up to I think 80 Gb interfaces. Another major benefit.
