Cell-Based Architecture
containing blast radius through cells

01 / THE SHORT VERSION
The idea in a few sentences.
An architecture pattern that splits infrastructure into multiple, identical, self-contained scale units (cells). An issue in one cell never affects others.
02 / FOLLOW THE MECHANISM
How routing transitions flow
Ingress Router
receives user request and extracts routing key (e.g. customer ID).
Cell Mapping
looks up database or hashes key to determine the active cell ID.
Isolated Execution
routes traffic to Cell-3 which contains its own database and load balancers.
Blast Boundary
if Cell-3 encounters a database lock, Cell-1 and Cell-2 continue operating unaffected.
04 / COMMAND NOTES
Read the command, then the result.
Inspect the flags and arguments before trying an example. Snippets can need local setup, replacement values, or resources in your own environment.

Could you explain Cell-Based Architecture to a teammate?
Try it out loud in two sentences: what it is, and the one detail that changes the picture. If you stall, the gap is the part to reread.
