Amazon's Cloud May Provision 50,000 VMs a Day

Dan Jones writes "It has been estimated that Amazon Web Services is provisioning some 50,000 EC2 server instances per day, or more than 18 million per year. But that may not be entirely accurate. A single Amazon Machine Image (the virtual machine) may be launched multiple times as an EC2 instance, thereby indicating that the true number of individual Amazon servers may be lower, perhaps much lower, than 50,000 per day. So, even if it's out by a factor of 10 that's still 1.8 million VMs per year. Is that sustainable? By way of comparison, In February of this year, Amazon announced S3 contained 40 billion objects. By August, the number was 64 billion objects. This indicates a growth of 4 billion S3 objects per month, giving a daily growth total of about 133 million new S3 objects per day. How big can the cloud get before it starts to rain?"
