Why Apply Modular Architecture in Mobile App Design
Modular architecture in mobile app design and development is a way to subdivide applications into several modules (functional units), components and subsystems, with the ability to replace or add any module without affecting the rest of the system as changes in business and customer expectations arise over time.
The importance of a well-designed software architecture
The architecture of a mobile application is a set of elements and techniques that define how the internal structure of an application's code should be and evolve over time. It is paramount to plan it well given that your architectural decisions will have lasting consequences.
Often companies focus solely on aspects such as UX, usability or design, whereas reliability, maintainability, scalability and low fault tolerance are often neglected. The result of this is an application that initially meets the expectations of both the company and the end-users, but in the long run, becomes challenging to maintain and extend its functionalities. Meanwhile, end-users await new features and fixed bugs that never come.
Let’s look beyond the UX and graphic design, and dive into the App backend — the submerged part of the iceberg doing the job behind the screen, often in a cloud server.
You’d ask — Is that where Modular Architecture comes into the picture?
Exactly. As your application grows, you will want the process of updating and modifying the app to be as seamless as possible. By starting off with a modular architecture you will have control over your app's reliability, maintainability, and scalability while providing an excellent forefront for the end-user and the company's technical resources. This type of architecture existed already but is an evolving trend.
