10 Common Software Architectural Patterns

Software architectural patterns are the backbone of modern software development. These patterns offer solutions to common design challenges, enhance the software architecture development lifecycle, and are essential considerations for software development companies and those offering software maintenance services.

1. Layered Architecture

Overview: The Layered Architecture pattern, also known as the N-Tier Architecture, divides an application into multiple layers, each responsible for a specific set of functionalities. These layers, typically including presentation, business logic, and data access, help in achieving separation of concerns.
Benefits: Layered architectures promote modularity, making it easier to develop, test, and maintain different parts of the application independently. They also facilitate scalability, as each layer can be scaled horizontally or vertically as needed.
Use Case: This is best for the wide range of applications, which includes web and enterprise, in which a clear division of concerns is required.

2. Serverless Architecture

Overview: Serverless architecture reduces the requirement for managing servers. It allows developers to focus solely on writing code while cloud providers manage the infrastructure. Serverless functions are event-driven and executed in response to specific events or triggers.
Benefits: Serverless architectures offer automatic scaling, reduced operational overhead, and cost efficiency. Developers can focus on writing code without worrying about server provisioning or maintenance.
Use Case: Serverless is ideal for applications with variable workloads and sporadic traffic patterns. It is commonly used for web APIs, data processing, and IoT applications.

3. Hexagonal Architecture (Ports and Adapters)

Overview: Hexagonal Architecture, also known as Ports and Adapters, emphasizes the separation of the core application logic from external dependencies. It defines clear boundaries (ports) through which the application interacts with external systems (adapters).
Benefits: Hexagonal Architecture enhances testability, adaptability, and maintainability. It isolates the core business logic from external services, making it easier to replace or mock dependencies for testing.
Use Case: Hexagonal Architecture is suitable for applications that need to interact with various external systems, databases, or services.

4. Event Sourcing

Overview: Event Sourcing is a pattern where the state of an application is determined by a sequence of events rather than the current state. Events are stored, and the application's state can be reconstructed by replaying these events.
Benefits: Event Sourcing provides a full audit trail of changes, enables temporal queries, and supports advanced analytics. It is useful in scenarios where historical data tracking is crucial.
Use Case: Event Sourcing is often used in systems like financial applications, audit trails, or applications requiring compliance with data retention regulations.

5. Model-View-Controller (MVC)

Overview: MVC is a design pattern used for organizing the codebase of user interfaces. It separates the application into three interconnected components: Model (data and business logic), View (user interface), and Controller (handles user input and orchestrates the Model and View).
Benefits: MVC promotes the separation of concerns, making it easier to maintain and extend user interfaces. It also facilitates code reusability and testability.
Use Case: MVC is commonly used in web applications and desktop software where a clear separation between the user interface and underlying logic is essential. By keeping in mind the current software trends, many developers use Model View Controller Architecture for its efficiency in devising data, which improves the flexibility of apps.

6. Microservices Architecture

Overview: Microservices is an architectural pattern that decays a perplexing application into a bunch of more modest, inexactly coupled administrations that can be created, conveyed, and scaled freely.
Benefits: Microservices promote agility, scalability, and fault isolation. They enable teams to work on smaller, focused components, making it easier to maintain and update the system. Additionally, they support the use of different technologies for each service, allowing flexibility in technology choices.
Use Case: Microservices are ideal for large, complex applications and for organizations that require rapid development and deployment of services. They are commonly used in cloud-native and containerized environments.

7. Service-Oriented Architecture (SOA)

Overview: SOA is a compositional example that structures programming as an assortment of administrations. Administrations are intended to be independent, reusable, and open over an organization. They communicate through standardized protocols like HTTP and can be composed to create larger applications.
Benefits: SOA fosters reusability, interoperability, and flexibility. It allows organizations to expose their capabilities as services, making it easier to integrate with other systems and adapt to changing business needs.
Use Case: SOA is well-suited for enterprises that want to expose their existing systems and capabilities as services, promoting interoperability and agility.

8. Event-Driven Architecture (EDA)

Overview: Event-driven architecture is centered around the concept of events, where components communicate by producing and consuming events. Events represent meaningful occurrences within a system and can trigger actions in other parts of the application.
Benefits: EDA enables loose coupling, scalability, and real-time responsiveness, especially helpful for frameworks where occasions assume a focal part, like IoT applications, monetary frameworks, and constant investigation.
Use Case: EDA is suitable for applications that need to react to real-time events, such as stock market trading systems or systems that process sensor data.

9. Repository Pattern

Overview: The Repository Pattern abstracts the data access layer from the rest of the application. gives a bunch of strategies for questioning and controlling information without uncovering the hidden information source (e.g., a data set) straightforwardly
Benefits: The Repository Pattern enhances testability, maintainability, and flexibility. It allows developers to change the data source or database technology without affecting the application's core logic.
Use Case: The Repository Pattern is valuable in applications that require data abstraction and where the choice of data storage technology may change over time.

10. Reactive Architecture

Overview: Reactive Architecture is designed to handle asynchronous and event-driven scenarios. It embraces principles like responsiveness, resilience, and elasticity, ensuring that systems can react to changing workloads and failures.
Benefits: Reactive Architecture supports real-time data processing, fault tolerance, and efficient resource utilization. It's appropriate for frameworks that should give high accessibility and low inertness.
Use Case: Reactive Architecture is regularly utilized in applications that handle continuous information, like web-based gaming, social media, and IoT platforms.

What Are the Key Factors to Consider When Selecting a Software Architecture or Design?

When selecting a software architecture or design pattern for a project, several key factors come into play. It is necessary to make the right choice when it comes to meeting the functional and nonfunctional requirements with providing facilities such as flexibility, and adaptability.

Complexity of the Problem Domain: Some projects deal with complex problem domains that require sophisticated solutions. Event-driven architectures and event sourcing are suitable for systems where events play a central role, while simpler domains may benefit from layered architectures.
Team Expertise: Assess the expertise of the development team. Are they familiar with certain patterns or technologies? Choosing a pattern that aligns with the team's skills can expedite development and reduce risks.
Performance Requirements: High-performance systems may require specialized patterns like reactive architectures. Consider whether the pattern can meet the performance demands of the project.
Security and Compliance: Security and compliance requirements should not be overlooked. Some patterns, like microservices, may introduce security challenges due to increased network communication. Ensure that the selected pattern aligns with security and compliance needs.
Use of Third-Party Services: If the project relies heavily on third-party services or APIs, consider how the selected pattern integrates with these services. Some patterns may facilitate easier integration than others.
Documentation and Resources: The availability of documentation, tutorials, and resources related to the pattern is essential for the development team's ability to adopt and implement it effectively.
Project Requirements and Goals: In any project, understanding the specific needs is mandatory, whether it is a web app, a mobile app, or an enterprise-level system. Knowing the project's scope helps in selecting the most appropriate pattern.
Scalability: Scalability is important, especially in present-day software systems. Will the application need to handle a growing number of users or data? Some patterns, like microservices and serverless, are inherently scalable, while others may require more effort to scale.
Future Proofing: Think about the long-term viability of the pattern, whether it is compatible with the present software development trends or will stay constant in the upcoming future. Patterns that are widely adopted and supported by a strong community are generally safer bets.
