Foraging for the Fallacies of Distributed Computing (Part 1)

Foraging for the fallacies of distributed computing!

Assumptions gone wrong

What exactly IS a fallacy when it comes to distributed computing?

We can think of the eight fallacies as eight common misconceptions that developers of distributed systems often fall prey to, which we want to avoid.

The 8 fallacies of distributed computing
  1. The network is reliable.
  2. Latency is zero.
  3. Bandwidth is infinite.
  4. The network is secure.
  5. Topology doesn’t change.
  6. There is one administrator.
  7. Transport cost is zero.
  8. The network is homogenous.

The trouble with networks

Fallacy #1: The network is reliable (it is not).
Latency versus bandwidth

Some fallacies hurt more than others

Fallacy #2: Latency is zero (it is not).

Some latency is a limitation of networks; we should be wise to not build a system that assumes that such a delay is nonexistent. We will certainly be bitten by such a false assumption in the future.

Fallacy #3: Bandwidth is infinite (it is not).
Fallacy #4: The network is secure (it DEFINITELY is not!).
