System Design
1. Major Aspects
- the ability of a system to continue to behave as expected in the face of significant upward or downward changes in demand.
- the system property and design strategy in which a system's components have minimal knowledge of any other components.
- internal changes to one don't demand changes in the other
- web servers and web browsers for instance are loosely coupled given both have certain guarantees.
1.2.1. Enablement
- Having a Protocol allows standardizing the input expectations and output assurances of a component.
- These may be addressed as Interfaces as well.
- see also fault tolerence
- the measure of how well a system withstands and recovers from errors and faults
- the ease with which a system's behaviour can be modified to keep it secure, running smoothly, and compliant with changing requirements.
- the measure of how well a system's internal states can be inferred from knowledge of its external outputs.
