Question

wat's "graceful degradation" and what's the difference b/n clustered systems and distributed systems?

Answer 1

Graceful degradation means that when a fault occurs in a system, it won't lose or corrupt any data that you have already entered, though its performance may degrade (e.g., processing or response times may slow down). It is also considered graceful degradation if the system terminates your processing but remembers its state so you can start up where you left off when the system is restored. In real-time control systems, part of graceful degradation is bringing the controlled machine or process to a safe shut-down state before terminating the control processing.

In clustered systems, the processors are co-located so they can exchange data at high speeds via backplanes or fibre optic links. Distributed systems are geographically dispersed and may even be located on separate continents, so the speed of data exchange is typically much slower than in clustered systems.
