On the HUB I've bought a reserved instance once for my medium instance server and found that it's only Medium Utilization Reserved Instance ($250, 3 years, $0.025/hour).
Checking Amazon's Reserved Instances there's Heavy Utilization ($300, 3 years, $0.020/hour).
Now that I've created a new medium instance server, my question is: How can I purchase the Heavy Utilization Reserved Instance via the HUB? It's a server running 24x7 so I'll save a lot if I can buy a Heavy Reserved one.
I bought a reserved instance via AWS console once but it doesn't show on the HUB. That's why I want to buy it via the HUB instead.
Any advice would be thankful.
