Different Software Architecture Patterns, and How to Choose the Right One for Your Task

In this post, we aim to provide insights on software architecture patterns by answering common questions such as: What constitutes a software architecture pattern? How many architectural styles are there? Furthermore, we will outline recommendations for selecting an effective software architecture pattern and provide real-world scenarios where standard software architecture patterns would prove advantageous.

Let’s begin, every worthwhile endeavor has to start somewhere.

Software architecture plays an integral role in the success of any software program, impacting its maintainability, scalability, stability, and security during its entire lifespan. The appropriate architecture is a vital component of achieving a thriving software development process, and it is crucial to establish a robust architectural framework before initiating development.

You can also explore our recommendations for a successful software development.

In order to generate a comprehensive system architecture, Software Architects must follow the Software Architecture Development Life Cycle’s four critical stages. These phases comprise Architectural Requirements Analysis, Architectural Design, Architectural Documentation, and Architectural Assessment, where each stage represents a distinct phase of the design process. Software Architects must complete each phase of this cycle in order to produce a precise and comprehensive depiction of the software architecture.

Taking advantage of system architecture diagrams created by Software Architects can greatly streamline the deployment of new software. These diagrams serve a variety of functions, including aiding in network updates, outlining long-term goals, and anticipating business needs. By incorporating these diagrams, companies can benefit from the knowledge and skill of Software Architects while bypassing the expense of software development.

With the growth in complexity of software and web-based applications, it is imperative for developers and stakeholders to have reliable system architecture diagrams for effective communication. These diagrams enable a more comprehensive understanding of the system, promoting efficient collaboration and problem-solving. By utilising these diagrams, stakeholders can obtain a comprehensive perspective of the software architecture, leading to seamless collaboration and swift resolution of challenges.

If you are unfamiliar, here’s a brief explanation of software architecture.

Software architecture refers to the comprehensive description of the fundamental traits and components of a software system. It entails encapsulating the structural and functional aspects of the system, along with their integration into larger subsystems, in order to accomplish the system’s intended purpose. This discipline of design principles provides an understanding of the overall structure and design of the system, as well as its alignment with its surroundings and context. To learn more about software architecture, check out the Software Architecture page on Wikipedia.

The key to achieving desired levels of performance, fault tolerance, scalability, and reliability as your program grows is through optimal design. By meticulously selecting an appropriate architecture for your program, you can guarantee consistent performance even in the most challenging of situations.

Through strategic planning that considers the long-term objectives of your product and how best to communicate this vision, your team will be well-prepared to make informed decisions and take appropriate actions, even in the absence of projected increases in customers.

The classification of software architecture patterns falls under five distinct categories.

Acquiring a comprehensive understanding of software architectural patterns can be an incredibly useful tool, bolstering your ability to complete tasks in a swift and efficient manner. To provide an overview of the various types of patterns available, we have identified five common categories that are outlined below.

  1. Stacked Design

    As the name suggests, subtasks are stacked one on top of the other in this structure.

    Each layer of this design operates independently and seeks to achieve its own objectives. This independent operation of each layer allows changes to be made to one layer’s code without affecting other layers.

    This pattern is widely used for software creation and corresponds to the concept of “N-tier architecture.”

    There are four distinct levels to this design, which are listed below:
    1. Presentational Depth:

      The layer of an application that enables users to visually interact with it and submit information.
    2. The Business Layer:

      The layer where requested business logic is executed.
    3. Functionality from the Application Layer:

      The layer positioned between the display and data layers that enables communication between the two.
    4. Statistics Layer:

      The data management layer.

      Well-suited for: Developing software for online stores. For example, the Amazon App Store.
  2. Client-Server Architecture

    The client-server architecture is rooted in the interdependent relationship between two distinct components: the client and the server. The client initializes a request for specific files or other resources stored on the server. In response, the server generates a reply. This back-and-forth communication is essential to the client-server architecture.

    Several programs that employ this design pattern include:
    1. Email
    2. WWW
    3. Applications designed for exchanging data files
    4. Applications designed for banking services

      Well-suited for: Multi-purpose applications that require robust security measures. Gmail is a prime example.
  3. Sequence of Events

    Software services can respond to external events with the help of an event-driven architecture pattern.

    What exactly does this signify?

    The event-driven architecture of an application allows the system to dynamically respond to user input. For example, when a user creates a Facebook account, their registration is finalized as soon as they fill out and submit the form. Here, the user’s submission of the form is the event that triggers the process of creating their account.

    Ideal for: Developing JavaScript-based websites and online stores. An example of this would be swiping a credit card.
  4. Microkernel Format

    The microkernel structure comprises two essential components: the Application Central System (A) and the plug-in modules (B). The central system is responsible for managing the program’s core functions, while the plug-in modules provide supplementary capabilities.

    These elements feature a central system and additional “plug-in” modules.

    If you have devised a powerful messaging software that can send and receive text messages with anyone around the world, irrespective of their internet connection status, you may want to incorporate voice chat functionality to the app. This would enable users to communicate via voice along with text, giving them a comprehensive messaging experience.

    Thanks to its microkernel design, it is possible to expand the capabilities of an existing application by implementing plug-ins. This method allows for easy addition of features without any need for restructuring the application.

    Perfect for: Software designed for product- and time-management. Examples include Instagram highlights, YouTube ads, and YouTube shorts.
  5. Microservices Design

    The microservices paradigm utilises a set of independent yet interdependent services to construct an application. Instead of developing a large, single application, each service is created as an individual program. These smaller programs are then combined to form a comprehensive application.

    Incorporating new features is made simpler when an application is designed using the microservices paradigm.

    The implementation of a microservices architecture in software development facilitates loose coupling between components, making them more comprehensible, adjustable, and extensible. Netflix is a well-known example of this, using microservices architecture in its software.

    Perfect for: Websites and software comprising numerous small components. Spotify is a great example.

Nevertheless, in the end

The Broker, Event-Bus, Pipe-Filter, and Blackboard design patterns are all valuable architectural patterns for software development. These designs serve the same purpose of defining the fundamental components of a program to enhance its effectiveness and efficiency. By employing these patterns, developers can design a software system that is practical and efficient.

It is vital to comprehend the purpose of a specific architectural design before selecting it. Neglecting to do so may cause project delays and potentially lead to an unsuccessful software product.

Hence, it is crucial to have an in-depth understanding of architectural patterns and the situations where they’re best suited. By doing so, you’ll be able to choose the architecture pattern that’s most appropriate for your software needs. Additionally, it’s recommended to seek out experienced software architects who have expertise in the diverse software design patterns.
