5. Security and Ethics Challenges

  • Data Privacy: Ensure that user data is stored securely in the cloud, adhering to GDPR and other regulatory requirements.
  • Security of Cloud Infrastructure:
    • Use secure Kubernetes configurations, such as role-based access control (RBAC) and network policies.
    • Ensure that communication between services is encrypted.
  • Ethical Considerations: Minimize the impact of downtime during deployments and ensure that users are informed of changes to the service.
  • Public Cloud Implications: Hosting sensitive financial data on public cloud infrastructure requires strong security measures to prevent unauthorized access.

6. Implementation of Services

  • Microservices: Implement mock services representing the core functionality (User Service, Trade Service, Notification Service) using Flask or a similar lightweight framework.
  • Kubernetes Artifacts:
    • Deployment YAMLs: For deploying each service to Kubernetes.
    • Service YAMLs: To expose each service via Kubernetes Service object.
    • ConfigMaps and Secrets: To manage environment-specific configurations and sensitive information.

7. Test Automation

  • Test Suite: Implement a test suite that automatically validates the deployment after each release.
  • Automated Testing Tools: Use tools like Jenkins, GitHub Actions, or CircleCI for running the test suite automatically.
  • Types of Tests:
    • Unit Tests: For individual service logic.
    • Integration Tests: Ensure proper communication between microservices.
    • End-to-End Tests: Validate the entire workflow from user authentication to trade execution.

8. RunBook

Deployment Steps:

  1. Checkout Code: git clone the repository.
  2. Build Docker Image: Use Docker to build images for each service.
  3. Deploy to Kubernetes: Use the provided Kubernetes artifacts to deploy the services.
  4. Blue-Green Deployment: Deploy new services in the Green environment, then switch traffic to Green after validation.

Test Steps:

  1. Run the automated test suite to ensure the application is functioning as expected.
  2. Monitor logs and performance metrics through Kubernetes dashboards.

9. Conclusion

Summary: This report presents a comprehensive solution for the Coinbase crypto exchange, focusing on containerization, automation through CI/CD pipelines, and ensuring uptime through Blue-Green deployments. The use of Kubernetes provides scalability and high availability, while security measures ensure data integrity and privacy.
