DOS 1.x (1981) had no explicit memory management support. It was designed to run primarily on machines with 64K RAM or less, or not too much more (the original PC could not have more than 64K RAM on the system board, although RAM expansion boards did exist).

For instance, do I need to run the application (service) on many instances (pods)? If so, would the design allow for that? How about ensuring that the alarm goes off only once? All of these could be requirements (NFRs/architectural characteristics) that the design must support.
