“ A cell router is responsible for detecting failure within a cell (Zombie outbreak) and rerouting requests (Citizens) to other neighborhoods.”<p>Misleading. The difference between a pure horizontally-scaled cluster and cell-based architecture is that traffic destined for a compromised cell does not get routed to a healthy cell. Fault isolation (preventing noisy neighbors and poison pills from spilling over to progressively more cells) is a primary tenet of cell-based architecture.
I'm sure this will come in handy for me at some point. I've led a team through moving parts of their terraform/aws monolith to cells. Some people are able to grasp what cell-based architecture is and when it's useful pretty easily, but for a few it just doesn't click.
