EC2 is a service provided by Amazon for creating virtual systems that run
on their network, for which users are charged by the machine-hour. Cloudmin can
be used to create and manage EC2 instances, just like it can for Xen and
VServer instances that run on your own machines. However, before you can
create new virtual systems via EC2, you must sign up for an account with
Amazon and provide your billing details. This can be done at
Amazon's AWS website.
Once you have an EC2 account, register it on this page by clicking on
the Add an EC2 account link. To manage an existing account, click on
its description in the list. To remove accounts, select the checkboxes next
to them and click the Delete Selected Accounts button. You will not
be able to remove accounts that are in use by any virtual systems though.
