In addition to the information that appears in the deployment architecture, you must specify the operating system that will be used on each computer used in your solution. You must also develop more information about the hardware. Your decisions will be based on your quality of service requirements, and represent your best guess at the hardware and operating system required to satisfy your qualify of service requirements.
For the example deployment architecture shown in Figure 2–1, the quality of service requirements were stated as:
To meet these quality of service requirements, the operating system and computer hardware specifications in Table 2–1 were developed.

You must develop similar information for the computer systems used in your solution.
The Computer Hardware/OS specification is complete in itself. Once the specification is complete, the computer systems can be set up. Memory and disk drives can be installed, operating system can be installed, and the system made ready for installation of Java ES components.
