- When linking two systems, with one system providing data to another system, the providing system's physical environment must be sized for the capacity of the requesting system and the reliability of the requesting system. Another way of saying this is that the providing system must meet or exceed the quality of service or SLA of the requesting system. - In the example I was reviewing, the HR system was the base for the desired information and was sized for the user capacity of the HR department and the reliability impact of an outage of the HR department. If it is to be used as a real-time providing system for Department B, it's capacity must be increased from the HR department (10 users) to the capacity of the Department B user base, the main business area (3,000 users). It must also have it's redundancy increased to provide no outages. - Alternatively, when there is a mismatch between capacity and reliability of the providing system and requesting system, the ...
