This document discusses trends in APIs to expect in 2012. It predicts that enterprise APIs will go mainstream, with 30% of enterprises implementing APIs and 60% considering them. It also suggests that APIs will become the default access point for backend systems, and that API-centric architecture will focus on integration with apps and developers rather than people or processes. Additionally, it proposes that data will be brokered through APIs using free and paid models, and that enterprises will enable their data through RESTful APIs.

6. API Trends –
What to expect in 2012

7. Enterprise APIs go mainstream

8. Enterprise APIs go mainstream
Explosion in popularity of public APIs
… like Facebook, Twitter, etc.

9. Enterprise APIs go mainstream
The real revolution is in enterprise!

10. Enterprise APIs go mainstream
Enterprises of all sizes are API-enabling their back-end systems

11. Enterprise APIs go mainstream
Opening the aperture of the use of back-end systems to
enterprises
partners
independent developers

12. Enterprise APIs go mainstream
Large enterprises embracing APIs
telecom enterprises, like AT&T
retail enterprises, like SEARS

13. Enterprise APIs go mainstream
Expanded reach to developers sparks innovation
…cool apps drive business

14. Enterprise APIs go mainstream (WAG!!)
2011
- 10% enterprises doing APIs; 10% considering it
2012
- 30% enterprises doing APIs; 60% considering it

15. API-centric architecture

16. API-Centric architecture
Websites (portals) for people integration
SOA architecture for app-to-app integration
but…

17. API-Centric architecture
New API world focus on integration with apps and developers
…not with people (via portals) or processes (via SOA)

18. API-Centric architecture
Think outside-in - not - inside-out
…easy consumption (REST) "chatty" APIs

19. API-Centric architecture
Get comfortable handling
(unpredictable) demand
(rapidly changing) usage patterns

20. API-Centric architecture
APIs - the de facto and default access point for back-end systems

21. API-Centric architecture
Websites and some internal processes
become clients of the "new" API layer
no longer use back-end systems directly

22. API-Centric architecture
API layer delivered through the Cloud
…handle rapid and evolving provisioning

23. Data-centric APIs

24. Data-centric APIs
Huge market for data – Siri, WolframAlpha…

25. Data-centric APIs
Today’s models
- highly paid - custom feeds (Dun & Bradstreet)
- free-for-all - sea of xls/csv files on a website
(Data.gov)

26. Data-centric APIs
Today’s models
- highly paid - custom feeds (Dun & Bradstreet)
- free-for-all - sea of xls/csv files on a website
(Data.gov)
Tomorrow’s model
- in the middle
- data brokered by APIs
- free and freemium models co-exist

27. Data-centric APIs
Growing enterprises data becomes the primary business
…data through apps is the new business model

28. Data-centric APIs
Enterprises will API-enable their data
…RESTify

29. Data-centric APIs
Is it about easy consumption of silos? Or is it for clean linking across silos?

30. Data-centric APIs
While data sources might be motivated to publish clean,
linkable data, a more likely scenario is new data platforms
that cleanse and standardize and aggregate

31. Enterprise APIs for Analytics

32. Enterprise APIs for Analytics
Business automation for bottom-line improvements

33. Enterprise APIs for Analytics
Business optimization for top-line improvements

34. Enterprise APIs for Analytics
API-adoption juggernaut focused on business automation

35. Enterprise APIs for Analytics
However, the future of APIs is business optimization
Business Business APIs

36. APIs optimized for the mobile developer

37. APIs optimized for the mobile developer
Mobile apps drive API development and adoption

38. APIs optimized for the mobile developer
Multiple devices – multiple requirements

39. APIs optimized for the mobile developer
Today
- mobile apps for iPhone (iOS) and Android

40. APIs optimized for the mobile developer
Today
- mobile apps for iPhone (iOS) and Android
Trend
- HTML5/JavaScript for apps that can run on any device

41. APIs optimized for the mobile developer
Mobile devices need to receive less data in API responses
Shouldn’t need to make repeated API calls to perform
simple tasks

42. APIs optimized for the mobile developer
Inefficient APIs make things worse for
app developer
API provider

43. APIs optimized for the mobile developer
Problems are multiplied by mobile demand patterns many
small API requests
Concurrency the sheer number of devices hitting the API
at once

44. APIs optimized for the mobile developer
Let developers filter the size and content of the API response
before it's returned to the app

45. APIs optimized for the mobile developer
Give developers the right format for their app environment
plist for iOS
JSONP for HTML5/JavaScript

46. OAuth 2.0 – the default security model

47. OAuth 2.0 – the default security model
In 2012 OAuth will become the default choice for securing
APIs that enable end-users to interact through apps with
their valued services

48. OAuth 2.0 – the default security model
Apps are the new intermediaries in the digital world

49. OAuth 2.0 – the default security model
Apps put buyers and sellers together
buyer = end user
seller = API provider

50. OAuth 2.0 – the default security model
Great apps package the provider's API in
…a great user experience

51. OAuth 2.0 – the default security model
Adoption
users can explore and try an app without compromising their
private data and privileges services like Salesforce.com, Twitter,
Facebook, eBay, . . .

52. OAuth 2.0 – the default security model
User can terminate the app's access to their account if
they don't like or don't trust an app

53. API Trends
Enterprise APIs go mainstream
API-centric architecture
Data-centric APIs
Enterprise APIs for Analytics
APIs optimized for the mobile developer
OAuth 2.0 - the default security model
