Both linux and windows reserved instances have the same deposit, so can I switch between the two?
1 Answer
Unlike normal on-demand EC2 instances (where the image decides the OS), the RESERVED instances cannot be changed after purchasing. To quote the official documentation:
Platform (e.g. Linux/UNIX, SUSE Linux, Windows Server, or Amazon VPC with either Operating System), Instance Type, Availability Zone, and term length must be chosen at purchase, and cannot be changed later.
