Cell-Based Architecture containing blast radius through cells
IN 10 SECONDS
An architecture pattern that splits infrastructure into multiple, identical, self-contained scale units (cells). An issue in one cell never affects others.
GOTCHA Managing migrations and database schema updates across dozens of isolated cells increases operational overhead.
HOW ROUTING TRANSITIONS FLOW
01 Ingress Router receives user request and extracts routing key (e.g. customer ID).
02 Cell Mapping looks up database or hashes key to determine the active cell ID.
03 Isolated Execution routes traffic to Cell-3 which contains its own database and load balancers.
04 Blast Boundary if Cell-3 encounters a database lock, Cell-1 and Cell-2 continue operating unaffected.
