+----------------+----------------------------------------+-------------------------------------+

3. High-Level Architecture Diagram
----------------------------------
Include a diagram illustrating the major components and how they interact.

4. Data Flow
------------
Explain how data flows through the system, including key touchpoints for input, processing, and output.

4.1. Data Flow Description
~~~~~~~~~~~~~~~~~~~~~~~~~~
1. **User Input:** User sends data via the frontend.
2. **API Gateway:** Request is routed to the appropriate service.
3. **Backend Services:** Services process the data and interact with the database.
4. **Response:** Processed data is returned to the user.

5. Technology Stack
-------------------
List the technologies and tools used in the system.

+-----------------+----------------------+
| Technology      | Purpose             |
+=================+======================+
| React           | Frontend framework   |
+-----------------+----------------------+
| Go              | Backend development  |
+-----------------+----------------------+
| RabbitMQ        | Message broker       |
+-----------------+----------------------+
| MariaDB         | Database             |
+-----------------+----------------------+
| Docker          | Containerization     |
+-----------------+----------------------+


6. Component Architecture
-------------------------
Provide a detailed description of each component, including interfaces and dependencies.

6.1. ExampleService
~~~~~~~~~~~~~~~~~~~~
- **Description:** Core service that handles business logic.
- **Dependencies:** Database, message broker.
- **Interfaces:**
  - REST API (`/api/v1/example`)
  - Message queue (`queue.example.events`)

6.2. Database
~~~~~~~~~~~~~
- **Description:** Persistent storage for application data.
- **Technology:** MariaDB.
- **Tables:**
  - `users`: Stores user information.
  - `transactions`: Stores transaction records.

7. Security Considerations
--------------------------
Detail the security measures implemented in the system.

- **Authentication:** OAuth 2.0 with JWT.
- **Data Encryption:** TLS for data in transit, AES for data at rest.
- **Role-Based Access Control:** Different roles for admin, users, and services.

8. Scalability and Performance
------------------------------
Describe how the system is designed to handle growth and maintain performance.

- **Load Balancing:** Requests are distributed across multiple servers.
- **Horizontal Scaling:** Microservices can be scaled independently.
- **Caching:** Frequently accessed data is cached to reduce database load.

9. Deployment Architecture
--------------------------
Describe how the system is deployed, including environments and CI/CD pipelines.

9.1. Environments
~~~~~~~~~~~~~~~~~
+---------------+----------------------------+
| Environment   | Description               |
+===============+============================+
| Development   | Local testing and development |
+---------------+----------------------------+
| Staging       | Pre-production testing     |
+---------------+----------------------------+
| Production    | Live environment           |
+---------------+----------------------------+

9.2. CI/CD Pipeline
~~~~~~~~~~~~~~~~~~~~
Explain the CI/CD process, including automated testing, build, and deployment steps.

10. Monitoring and Maintenance
------------------------------
Describe the monitoring and maintenance strategy for the system.

- **Monitoring Tools:** Prometheus, Grafana.
- **Logs:** Centralized logging using Elasticsearch.
- **Alerts:** Configured alerts for critical system events.

11. Future Enhancements
------------------------
Outline potential future improvements to the architecture.

- **Improved Caching Strategy**
- **Serverless Functions for Event Handling**
- **Multi-Region Deployment**
