Scope

When you need to scale vertically, i.e. change the available vCPUs or RAM assigned to a VM in OTC, you can use the resize (change specifications) feature and change the flavor of an existing VM. You can do this via the web interface or the API -- when you then restart the VM, it will come up with the new flavor type.
