Picked this up from Reuven Cohen @ Enomaly's blog: The Business of Cloud Computing is booming:
"An analysis by Guy Rosen also sheds some light on the cloud opportunity in which he estimates that Amazon Web Services (AWS) is provisioning 50,000 EC2 server instances per day. A 50K/day run rate would imply a yearly total of over 18 million provisioned instances. "
Read the rest of @ruv's post: this confirms something that we've noticed is that cloud provisioning provides up to 90% cost savings relative to traditional outsourced data centre hosting, PLUS with no vendor lock-in or minimum contract terms. Bring it on.
