With a Pay-As-You-Go VM instance, you can save a lot by shutting it down when you don't need it. Is there any advantage to doing that with a reserved instance? It's not like the term of the reservation is extended, is it? As I understand it, you're paying for the same fixed period of time whether the VM is running or not.
That is correct sir. The reservation is for a fixed time period. You have the option to choose from one or three years upon purchase. The reservation time period starts ticking away just as soon as you purchase it. This is not dependent if you have that specific VM size provisioned or not. You can track the utilization of the reserved instance from the overview page within the portal. So the long winded answer is shutting down the VM's when they are not in use will not extend your reserved instance time. This also applies to CSP software subscriptions. @Peter Yasuda
