3. Patterns 3 A generic solution for a common recurring problem.  Used it before  Error proof  Common way to communicate : architect’s language  Catalog to pick one : feel comfortable

4. Enterprise Architecture 4 “Manage the complexity of the IT environment and applies principles and techniques to reduce the complexity, improve efficiencies, and reduce capital and operational expenditure.”

6. Service Oriented Architecture (SOA) 6 “Architecture paradigm to build highly loosely coupled distributed systems”

7. SOA cont…. 7 “Nothing NEW, architecture style to fix the broken architectures”

8. SOA at kindergarten 8

9. SOA improved 9

11. SOA runtime view 11

12. 12  Less visibility to projects o Difficult to find o Availability o Ownership  Development cycles: o From 18 to 6 months to 3 months  Change management  Real standards o Technical (REST, SOAP, protobuf) o Business (ACORD, HL7, FIX, FAST)  Integration is key (extend to connected business) o Companies without integration are falling behind o Heterogeneous systems Enterprise Architecture has changed

13. 13 Next-Gen Middleware  Big-3 o Mobile o Social o Cloud  APIs  Big Data  DevOps  Open Source Picture Credit : http://www.latimes.com/sports/

15. Modern Applications are Systems of Systems

16. Gartner View of Systems of Systems

17. Forrester View of Systems of Systems Systems of record are technologies that manage and store transactions, content, and processes. Systems of engagement are technologies that directly support customer interactions through software. Systems of automation are technologies that intelligently manage physical products, networks, and infrastructure. Source: Forrester Research

18. Systems of Systems Functional Requirements

19. Supportive patterns 19  Event-Driven Architecture (EDA)  Web Oriented Architecture (WOA)  Enterprise Integration Patterns  Internet of Things (IoT)

20. How can I get there ?

21. Requirement stage 21 Requirements Current applications/systems Δ Delta

22. Approach (architecture) 22 Business Architecture Solution Architecture Level 0 Level 1 Application Architecture Integration Data models APIs Runtime Architecture Capacity Planning Deployment Security

23. Level 0 architecture 23

24. Level 1 architecture 24

25. Example : MDM L0 25

26. Example : MDM L1 26

27. What the Enterprise Looks Like Architecture

28. Identity/Access Control Architecture

29. Services – get the service platforms Architecture

30. Registry/Repository Architecture

31. Connectivity - internal Architecture

32. Connectivity - external Architecture

33. APIs Architecture

34. Monitoring, Analytics, Audits Architecture

35. CEP – real-time Architecture

36. Fill-in the Blanks Architecture

37. Middleware Platform 37

38. Do I need the entire platform ?

39. Beyond the middleware o Cloud o *PaaS to SaaS o Cloud native o ALM o AppFactory Private PaaS Private PaaS Public PaaS Public PaaS

40. Same programming model Same solution architecture Same (deployable) artifacts Cloud based deployment Cloud native applications

41. What will happen to the current system(s), data, people ?

42. Connect Old-IT and New-IT Architecture

43. People 43  Engage  Empower  Accountable  Iterative
