 Computing environment relationships and 
dependencies
The computing environment involves the collection of computer machinary, data 
storage devices, work stations, software applications, and networks that support the 
processing and exchange of electronic information demanded by the software solu-
tion. The computing environment involves the following relationships and depend-
encies with elements of the software architecture:
1. 
Technology availability (requirements baseline).
 The performance of the soft-
ware solution is constrained by the computing environment and must be fac-
tored into software product requirements. The number of intructions that can be 
excuted, data transfer rates, graphics resolution, and rendering rates are typical 
computing equipment measures that affect the subsequent performance of the 
software solution.
2. 
Resource utilization and conservation (software product architecture).
 The 
availability of computer resources within the computing environment will con-
strain software product performance. Shared resource utilization models must 
be developed, especially for networked multi-user applications. A strategy for 
managing resources that establishes resource consumption, conservation, pres-
ervation, and recovery must be developed and incorporated into the software 
archtiecture.
