I suggest we consider the limits of a sin
I suggest we consider the limits of a single nova deployment, not across
all regions. To Pete's point, at a certain scale, people will break into
parallel, independent nova deployments. A single, global, deployment
becomes untenable at scale.
I agree with Pete that 1M hosts (and 45M Vms) is a bi

Actually it was 1M hosts and Ivthink 45 million vms. It was meant to
be across all regions. Jason Seats set the number arbitrarily, but it
is a good target to not let us forget about scaling while we design.
I think eventually all loads will be more ephemeral. So, I think I
agree with your num
You are right. The 1M number was VMs not hosts. At least, that was from
one scale discussion we had within Rackspace. I'm not sure what the
"official" nova target limits are and I can't find anything on launchpad
that defines it. If there is something, could someone please send me a
link.

OK, good point. But, this begs the question: what should Nova's
priority be? Elasticit

In my opinion, such numbers are completely out of whack. Google's Chubby
article says that the busiest Chubby has 90,000 clients (not hosts!) and
the biggest datacenter has 10,000 systems.

We know Amazon is highly, highly elastic. While the instances launched
per day is impressive, we know that many of those instances have a short
life. I see Guy is now teaming up with CloudKick on this report. The EC2
instance ID enables precise measurement of instances launched, and
