Building Maintainable and Scalable Applications: Exploring Common Architectural Patterns

Building Maintainable and Scalable Applications: Exploring Common Architectural Patterns

You must have had a hard time maintaining and scaling them as they grow in size and complexity if you have been building software applications for some time. This is what architectural patterns aim to solve.

What are Architectural Patterns?

An architectural pattern is a problem-solution pair for a commonly occurring pattern in software architecture that can be applied to any system, or platform using any technology.

Let's see some of the widely used architectural patterns:

Model-View-Controller (MVC)

The MVC pattern is the most common pattern used in Web Development. This pattern separates the major components of the system into three parts: Model, View and Controller The model part handles and manages the database part usually required for the data and business logic, the view handles displaying of the data, and the controller handles the interaction between the model and the view.

Microservices Architecture

Microservices Architecture divides the system into smaller services, where each service is responsible for its task. The best part about this pattern is that each service can be developed, deployed, and scaled independently.

Serverless Architecture

Serverless Architecture divides the application logic into stateless functions which are then triggered by some kind of events and requests. It is generally associated with the misconception that no server is involved in this type of architecture. But it is more related to the fact that it does not involve setting up the servers for building and handling the logic of our system. It automatically scales and removes the hassle of infrastructure management.

Client-Server Architecture

Client-Server pattern is the general type of architectural pattern. In this pattern, the system is divided into: Client and Server. The client initiates a request and the server responds to it with a response. It is generally used in distributed computing applications.

Event-Driven Architecture (EDA)

Event-Driven Architrecture (EDA) is used in the system which deals with a lot of events. This type of pattern focuses on creating, detecting, and handling events. In this pattern, different components of the system communicate with each other through events.


While building maintainable, scalable, and robust software applications, architectural patterns are really important. We need to consider an architectural pattern that fits our application requirements.
