- 7. Episode 1 : Composition Pattern Problem Solution Benefits Considerations
- 8. Problem
- 9. Scenario: Mash-up App Service 1 Service 2 Client App on device Service 3
- 10. Problem Establish device connection to three hosts Negotiate API/Service security each time Normalize data format inside the app logic on the device
- 11. Multiple Service Mash-up Service 1 Network connection, negotiate security, data format & parsing Service 2 Client App on device Service 3
- 12. Solution
- 13. API Service Layer Service 1 API Service Service 2 Layer Client Service 3
- 14. An Example Service 1 Book a Cab App API 2. Book Cab Service Service 2 Layer Client Service 3
- 15. Benefits
- 16. One-time authentication by the device.
- 17. Fewer network calls from a device.
- 18. Plug in a different service provider without having to change the app.
- 19. Validate and control before the requests reach the backend.
- 21. Opportunity to use Backend-as-a-Service with no additional expense to the application logic.
- 24. Few other scenarios Parallel callouts Compensation Chatty Services
- 25. Parallel Callouts Service API Book a Cab App from Service present location Layer Client Service
- 26. Another Example: Chatty Services 1. Get user attributes Service 2. Get recommended topics Provide r 3. Get recommended books Client
- 27. Solution: Reduce Chattiness 1. Authenticate by API key API 2. Get relevant user topics Service Get a recommended Service 2 book for a user Layer 3. Get recommended books Client
