Jini and Network Computing/Eight fallacies of distributed computing

L. Peter Deutsch asserted:

Essentially everyone, when they first build a distributed application, makes the following eight assumptions. All prove to be false in the long run and all cause big trouble and painful learning experiences.

• The network is reliable
• Latency is zero
• Bandwidth is infinite
• The network is secure
• Topology doesn't change
• There is one administrator
• Transport cost is zero
• The network is homogeneous

This set of fallacies provide a wide range of responses and reactions, as one might imagine.
