In the first part of our exploration into the fallacies of distributed computing, we looked into four common misconceptions that can significantly impact the design and functionality of distributed systems: the reliability of the network, the illusion of zero latency, the myth of infinite bandwidth, and the false sense of inherent network security.

Now, in Part 2 of this series, we turn our attention to the remaining four fallacies, each presenting unique challenges and requiring careful consideration:

  1. Topology Doesn't Change: The oversight of network dynamics and their impact on system performance.
  2. There is One Administrator: The simplification of management responsibilities and control in distributed environments.
  3. Transport Cost is Zero: The underestimation of the resources required for data movement across the network.
  4. The Network is Homogeneous: The assumption that the network environment is uniform and consistent.

Fallacy 5: Topology Doesn't Change

This one is a misconception in distributed computing that disregards the dynamic nature of network topologies. Network topology, the arrangement of various elements (links, nodes, etc.) in a computer network, is not static. Changes can occur due to network expansion, hardware upgrades, outages, or reconfigurations. Designing systems under the assumption of a static topology can lead to significant issues when inevitable changes occur.
