My instance is running on Linux (kubernetes deployed by kops). From the billing I saw they are classified as "Linux/UNIX", but I think it is deployed in VPC via kops.
Now I want to buy reserved instance, and the choices of platform has two:
- Linux/UNIX (Amazon VPC)
- Linux/UNIX
Which one should I use? What are the difference?
BTW, once I bought a RI, do I have to wait to the next day to see the reservation coverage from billing UI? Can I see if it covers some of my running instance immediately?
