Splitting
Explore the concept of module splitting within system architecture to improve software resilience and modularity. Understand how breaking down modules reduces dependencies, supports parallel processing, and isolates failures, all while maintaining consistent interfaces to ensure stable system operations.
We'll cover the following...
Modules
Splitting breaks a design into modules, or a module into submodules. The following figure shows a system before and after splitting “Module 1” into three parts. This is often done to distribute work. Splitting requires insight into how the features can be decomposed so that cross-dependencies in the new modules are minimized and the extra work of splitting is offset by the increased value of more general modules.
Example of splitting
We start with a module that determines how to ship products to a customer. It uses the shipping address to decide how many ...
