1. API Design Optimized for Mobile Platform Gea-Suan Lin KKBOX, Inc.
2. KKBOX
3. Mobile Platform
4. Mobile Network Mobile Device
5. Compare to Landline
6. Network Part
7. Speed
8. Reliability
9. Latency
10. Device Part
11. It’s much slower.
12. So,
13. To adopt mobile environment,
14. We care about these two different faces
15. Client Modification
16. Server Modification
17. API Modification
18. First, Merge Operations
19. Reduce Connections
20. POST /login username= password= GET /check-version GET /rank/album/top100 GET /rank/song/top100 GET /rank/artist/top100
21. Merge to...
22. POST /login username= password= extra=check-version,rank-album- top100,rank-song-top100,rank-artist- top100
23. It’s dirty.
24. But it’s much efficient.
25. Second, Operation with Strict-Increasing Serial
26. Avoid Duplicate API Call
27. POST /mybox/room/1/ message message= serial=
28. Use database to store the serial of each device.
29. Third, Multiple Objects Design
30. Reduce Client CPU Resource
31. And Reduce Connections
32. GET /song/ 1,2,3,4,5,6,7,8,9,10,11, 12,13,14,15,16,17,18,19, 20
33. Fourth, Filter Results
34. Reduce Traffic
35. Reduce Client CPU Resouce
36. GET /song/ 1,2,3,4,5,6,7,8,9,10,11, 12,13,14,15,16,17,18,19, 20/name
37. Then...
38. Fifth, Compression
39. Reduce Traffic
40. Sixth, Use Port 80 & 443
41. Reduce Firewall Issue
42. Thank You!
