Deployment time
It takes time from deciding to deploy a new server instance to time when it is available for switching. 
On physical hardware: 
can take 30 minutes to build a server instance. 
On virtual machine
Can build a server instance in advance and keep it available and unused.
Can share memory between (exclusively activated) instances. 
Disk can't be shared (easily). 
In either case, 
60 seconds to boot a server instance. 
10 seconds to wake up a sleeping instance.
