Large Scale Deployment of SOA-PReal World Lessons Presentation by Steve Millidge

1. Large Scale Deployment of SOA-P Real World Lessons Steve Millidge Director, C2B2 Tuesday 4 th May

2. “ The ease of use of modern SOA enabling tools hides the technical complexity of implementing a reliable SOA technology platform, but developing an enterprise-wide reliable, scalable, high performance, secure and manageable SOA infrastructure requires a level of technical command that few organisations have been able to develop.” Massimo Pezzini - Gartner

3. Fast Reliable Manageable Secure

4. FAST

7. Reached Limit of a single “node”

8. Add more “nodes”

9. Service Review Service Invoker UDDI EPRs Protocol Gateway Listener Service Listener Action Pipeline Gateway Action1 Action 2 Action 3 Action 4

11. maxThreads property of the Listener

13. InVM Scope attribute on your Service Tag

18. Make use of Heterogeneous Service Deployment Client UDDI EPRs Heavy Memory Services Heavy CPU Services Fast Response Services

20. Code Configurable – write your own LB Policy

21. Each ESB Node can be independent Client Service Invoker Service Node 1 Service Node 2

22. Reliable

24. Design for Failure

26. Careful design of transaction boundaries

27. Detailed analysis of “moving parts”

28. SOA-P HA Technical Architecture Service Invoker Round Robin JMS EPR Custom HA UDDI lookup Client Host 1 Host 1 UDDI UDDI Local DB (MySQL) Local DB (MySQL)

31. Alert on potential failures

34. Can replies be lost for Request/Response

38. Manageable

45. Possible to write a Registry Interceptor to do version matching etc.

46. Isolate deployment classloaders

47. Secure

50. Breach of Confidentiality

51. Unauthorised operation

54. Lock down deployment routes

55. Audit configuration file changes

56. Secure individual services

57. Enable Identity Propagation

59. Enables “deep” authorisation and audit Authentication Boundary Inbound Service Authorising Service Identity

61. Recreated and JAAS login occurs before service called

62. Authorisation check performed

63. Fast Reliable Manageable Secure
