Consider an airline reservation system, where agents from any part of the world can make a reservation for seats on any flight on any airline.
One design for this system is to send all reservation requests to a single central computer.
This design is simple, but has two problems.
First, if the central computer crashes, every agent is affected.
Second, as the number of agents increases, we need to expand the capacity of the central computer.
However, the number of reservation requests, particularly during peak travel periods, may increase beyond the capacity of the largest computer that we can build or buy.
Then, the response time suffers, and system performance degrades.
We can solve this problem by replacing the central computer with a set of regional reservation center that coordinate among themselves to maintain a consistent view of the system state(such as whether a night is full or not).
Then, as the number of reservation requests increases, we can just add another reservation center.
We must, however, pay for this with a communication overhead for coordination, and a complex network to interconnect the regional reservation centers.
