- The [blank_start]process[blank_end] view: the set of independently executing processes
that will exist at run-time and the communication between them.
- The [blank_start]deployment[blank_end] view describes how the system will be deployed to an operating environment in terms of the physical computers.

the run-time elements will be and where they will be deployed – the
[blank_start]application environment[blank_end].
