You are responsible for the design of a communications switch that has to provide 24/7 availability, but which is not safety-critical. Giving reasons for your answer, suggest an architectural style that might be used for this system.
What will be an ideal response?
The clue here is in the question – the system is not safety critical so eliminates
protection systems. However, there is a need for availability so the most
appropriate architectural pattern is an N-version programming architecture or a
replicated server architecture with each server running a different OS.
