Re: First BASHing
AWS and Azure (and I assume Google) cloud services are not like a well built internal private virtualized environment. There is no vmotion or storage vmotion (or whatever the citrix and M$ version of this are). There is redundancy in networking (so we are told), but there is no separate path for storage or management.
The old AWS server has a single redundant 1Gb connection going out the server for everything - management, storage and regular network traffic. This is shared by all the VMs on that host. Few people in their right mind would set up a vsphere or hyper-v environment with these sorts of limitations. There are ways to pay for more bandwidth and IOPS with a 10Gb pipe, but those are significantly more expensive.
Lots of people make many assumptions about AWS based on what their own internal virtualization environment looks like, and they would be fools to do so. It is nothing like what one responsible person would set up, unless you were trying to be the cheapest cloud vendor in the world, then its whatever you could do to make it the cheapest possible setup.
