Re: The Business of Building Clouds

Adrien,

This might depend on specific configuration of hardware layer and configuration of cloud (in many cases virtualized environment). There's always a tradeoff in performance (around 10-15%), when using hypervisor, but this also might be optimized by using eficient drivers, written for known hardware (I/O is pretty crucial one). However virtualization brings very important features, not present in barebone layout.

Ray,

As a client perspective, I really like the fact to be able to compare
cloud features to what I am doing without the cloud. I take the example
of being able to say

before : how many HTTP request handling in GET/POST
after : how many HTTP request handling in GET/POST

before : how many SQL request handling in SELECT/INSERT
after : how many SQL request handling in SELECT/INSERT

I can compare a "cost per scalable INSERT" and evaluate what is better
for me. Not to move from cloud X to cloud Y but to able to move from
non-cloud to cloud and understand the offer in terms I already use with
our present platform.
