Modular Architecture

This approach refers to software architecture that can be built from self-contained modules which are deployed and developed independently. This allows for greater flexibility and speed when adapting to fast market changes.

What Modular Architecture Means

Modular architecture, or modularity, refers to a system made of separate components (modules) that are connected together, but not dependent on each other. Each task is completed by a single component, but one component can perform multiple tasks. In this way, a large number of tasks can be completed from a relatively small base of modules. Modularity is a key characteristic of Composable Commerce.

The opposite of modular architecture is the integrated or monolith architecture, in which there is no clear differentiation between the distinct modules that compose it.

The choice between modularity and integration is crucial because the strategy with which corporate resources will be deployed and the way the product itself will be designed will depend on it.

It depends on a multitude of factors: the product’s characteristics, the available know-how, and the market sector in which the business wants to position itself.

Modular architecture is represented by the design and use of a system built by components (modules) that function independently, but are interconnected.

Benefits of Modular Architecture

Quick development

The timing of software implementation, deployment, and updating are reduced.


As demand for certain services increases, modules can be deployed across multiple servers and infrastructures to meet business needs.


The failure or malfunction of one component, does not cause the entire app to crash, due to the independence of each service.

Ongoing growth

Flexibility and scalability allow for no limits to technological development, enabling ad hoc updates and remodeling of the application.
