AFAAQ / Capability / 04
Cloud
The platform everything else runs on.
Argument
Cloud is not a layer beside the others — it is the plate they sit on. It is the only capability that carries the whole composition rather than adding to it.
Role in the system
A foundation, not a component.
Cloud introduces the infrastructure layer: compute, storage, delivery and observability. Every other layer in the composition ends up resting on it, which is why it is drawn as a plate rather than a box.
Infrastructure decisions therefore propagate upward. What can be observed, what can be recovered and what can scale are all settled here, before any feature is written.
System effect
It carries the composition.
The composition below adds the infrastructure layer beneath everything already present. Nothing above changes shape — but everything above now has somewhere to run and something to be observed by.
