Migrating from Mule to Kong with PingFederate - ganmath/learners GitHub Wiki

1. Verify Kong Usage and Working in Application XX

Step 1.1: Documentation Review

  • Existing Documentation: Review existing documentation of Kong's implementation in application XX. Check for any gaps or missing information.
  • Create Documentation: If documentation is missing or incomplete, document the following aspects:
    • API Gateway setup and configuration.
    • Authentication and authorization mechanisms using PingFederate and JWT tokens.
    • Rate limiting, logging, and monitoring.
    • Load balancing and failover strategies.
    • Custom plugins or scripts used.
    • Detailed migration steps and challenges encountered.

Step 1.2: Functionality Verification

  • API Endpoints: Verify that all API endpoints are correctly configured and accessible through Kong.
  • Policies and Plugins: Ensure that all necessary policies (e.g., security, rate limiting) and plugins are functioning as expected.
  • JWT Token Validation: Ensure JWT tokens issued by PingFederate are correctly validated by Kong for both UI to backend and backend to backend calls.
  • Performance and Load Testing: Conduct performance tests to ensure that Kong is handling the expected load and performance metrics.

2. Verify Mule Usage and Working in Application YY

Step 2.1: Documentation Review

  • Existing Documentation: Review existing documentation of Mule's implementation in application YY. Check for any gaps or missing information.
  • Create Documentation: If documentation is missing or incomplete, document the following aspects:
    • API definitions and endpoints.
    • Authentication and authorization mechanisms, particularly focusing on how PingFederate is used.
    • Integrations with other services or databases.
    • Custom scripts or transformations used.
    • Logging and monitoring configurations.

Step 2.2: Functionality Verification

  • API Endpoints: Verify that all API endpoints are correctly configured and accessible through Mule.
  • Policies and Plugins: Ensure that all necessary policies (e.g., security, rate limiting) and plugins are functioning as expected.
  • JWT Token Validation: Ensure JWT tokens issued by PingFederate are correctly validated by Mule for both UI to backend and backend to backend calls.
  • Performance and Load Testing: Conduct performance tests to ensure that Mule is handling the expected load and performance metrics.

3. Perform Migration Using the Document Created Above

Step 3.1: Environment Setup

  • Development Environment: Set up a development environment for Kong, mirroring the production setup of Mule in application YY.
  • Testing Environment: Prepare a testing environment to validate the migration process before moving to production.

Step 3.2: Configuration Migration

  • API Endpoints: Replicate the API endpoints from Mule to Kong.
  • Policies and Plugins: Configure the necessary policies and plugins in Kong to match those used in Mule.
  • JWT Integration: Integrate PingFederate with Kong to handle JWT token validation for both UI to backend and backend to backend calls.
  • Custom Scripts: Migrate any custom scripts or transformations from Mule to Kong.

Step 3.3: Testing and Validation

  • Functional Testing: Conduct thorough functional testing to ensure that all API endpoints work correctly in Kong.
  • Performance Testing: Perform performance testing to ensure that Kong handles the expected load and meets performance criteria.
  • Security Testing: Validate the security configurations, ensuring that JWT tokens issued by PingFederate are correctly validated.
  • External Microservices: Test interactions with external microservices to ensure they are correctly authenticated and authorized using JWT tokens.

Step 3.4: Documentation and Training

  • Update Documentation: Update the documentation to reflect the new Kong configuration and migration process.
  • Training: Provide training to the development and operations teams on the new Kong setup, focusing on JWT token handling and best practices.

Step 3.5: Production Rollout

  • Staged Deployment: Implement a staged deployment strategy, starting with a small subset of APIs and gradually migrating all endpoints.
  • Monitoring and Support: Monitor the Kong setup closely for any issues and provide support for troubleshooting and resolving any problems that arise.

Additional Considerations

  • Rollback Plan: Prepare a rollback plan in case any critical issues are encountered during the migration.
  • Version Control: Use version control for configuration files and scripts to track changes and facilitate collaboration.
  • Backup: Ensure that all critical data and configurations are backed up before starting the migration process.

By following this updated strategy, you can ensure a smooth and successful migration from Mule to Kong for application YY, with proper handling of JWT tokens through PingFederate for both UI to backend and backend to backend calls.
