Cell-based Architecture (CBA) is a software design paradigm that structures applications as a collection of small, self-contained units called "cells." Each cell encapsulates specific functionality along with its own data, logic, and state, enabling independent development, deployment, and scaling. CBA is a approach that combines aspects of application architecture, deployment architecture, and organizational (people/team) architecture. This integration promotes modularity, agility, and efficient collaboration across development processes.

In cell-based architecture, applications are decomposed into multiple cells, each representing a bounded context with its own data, logic, and state. Cells interact with each other through well-defined interfaces, promoting loose coupling and high cohesion. This approach facilitates parallel development and allows teams to focus on individual cells without impacting the entire system.
