Microservice Architecture

In the noorAlmobin project, we have adopted a microservice architecture to enhance scalability, maintainability, and flexibility. This architecture allows us to divide the application into smaller, independent services that can be developed, deployed, and scaled independently.

Architecture Overview

The backend is divided into two main sections:

1. User Authentication Service:

   • This microservice is responsible for managing user accounts, handling authentication, and maintaining session states. It provides secure login, registration, and user management functionalities.
   • By isolating authentication concerns, we can ensure that user data is managed securely, and changes to authentication mechanisms can be implemented without impacting other parts of the application.

2. Information Services:

   • This section encompasses all other functionalities related to the application’s content, including access to the Quran, Nahj al-Balagha, the calendar, and other books.
   • This service handles data retrieval, storage, and processing, ensuring that users can seamlessly access the application’s features.

Future Expansion

One of the key advantages of a microservice architecture is its flexibility in accommodating future growth. As the needs of the application evolve, we can easily introduce new microservices to support additional features or functionalities. For example:

• New Content Services: If we decide to incorporate more religious texts or educational materials, we can create dedicated services for those resources without disrupting existing services.
• Analytics Service: We may add a service to analyze user behavior and improve the overall user experience based on data-driven insights.
• Notification Service: A separate service could be implemented to manage notifications for events, reminders, and updates.

Benefits

• Scalability: Each microservice can be scaled independently based on demand, allowing for efficient resource utilization.
• Maintainability: Isolating functionalities into distinct services makes it easier to manage, test, and deploy changes without affecting the entire application.
• Technology Agnosticism: Different services can be built using different technologies best suited for their specific tasks, enabling us to leverage the latest advancements in each domain.

Conclusion

By employing a microservice architecture for noorAlmobin, we position ourselves for future growth and adaptability. This approach not only improves the current structure of the application but also sets the stage for the integration of new features and services as the project evolves.

Sure, I can help you design system diagrams in Mermaid! Here are a few types of system design diagrams you might find useful:

1. High-Level Architecture Diagram

This shows the main components of a system and how they interact. Here's an example:

flowchart TD
    User -->|Requests| Frontend
    Frontend -->|API Calls| Backend
    Backend -->|Database Queries| Database
    Backend -->|Third-party API Calls| ExternalAPIs
    Backend -->|File Storage| Storage

    subgraph Client
        User
        Frontend
    end

    subgraph Server
        Backend
    end

    subgraph Data
        Database
        Storage
    end

    subgraph ThirdParty
        ExternalAPIs
    end

2. Microservices Architecture

This example illustrates a system with separate microservices for different functionalities.

flowchart TD
    User --> Gateway
    Gateway -->|Auth Requests| AuthService
    Gateway -->|Data Requests| DataService
    Gateway -->|Billing Requests| BillingService

    subgraph Microservices
        AuthService
        DataService
        BillingService
    end

    DataService -->|Database Queries| Database
    BillingService -->|Payment Gateway| PaymentService

3. Database Schema

Here’s an example of a database schema for an application with users, projects, and tasks:

    USER {
        int id PK
        string name
        string email
    }

    PROJECT {
        int id PK
        string name
        string description
        int user_id FK
    }

    TASK {
        int id PK
        string title
        string description
        date due_date
        int project_id FK
        int assigned_user_id FK
    }

    USER ||--o{ PROJECT : owns
    PROJECT ||--o{ TASK : contains
    USER ||--o{ TASK : assigned

    User->>Frontend: Sends Request
    Frontend->>Backend: API Call
    Backend->>Database: Query Data
    Database-->>Backend: Return Data
    Backend-->>Frontend: Respond
    Frontend-->>User: Display Data

5. Deployment Diagram

This shows the different environments for deployment, including servers and databases.

    subgraph Dev
        devServer[Development Server]
        devDB[(Development Database)]
    end

    subgraph Staging
        stagingServer[Staging Server]
        stagingDB[(Staging Database)]
    end

    subgraph Prod
        prodServer[Production Server]
        prodDB[(Production Database)]
    end

    devServer --> devDB
    stagingServer --> stagingDB
    prodServer --> prodDB
