Notes to myself
Section A
Why A2-option2 doesn't belong to A1?
- A1 uses one infrastructure. adding cellular network is interpreted as an external "instance" since cellular data is provided by external party.
- Same for A4-option2 and A3
Section C
- App Server at Institute 2 cannot act as DBE (encryption)
- App Server at Institute 1 can act as DBE (no encryption needed)
