What a mess ..... :-(
How can I make this better?

14. 14
Solution

SOA Governance can solve this problem

Governance applied to 4 phases
– Architectural Governance
– Design time Governance
– Operational Governance
– Organisational/Political Governance

15. 15
Ok.. show me how..

16. 16
Architectural Governance

hmm....ok..
now we have services
in production.
What's next?

My organisation follows
an adhoc methodology...

35. 35
Organisational/Political Governance

36. 36
Show me how the scenario
changes after following
all these..

37. 37
SOA Governance applied...

38. 38
Hmm.. looks lot cleaner..
How to identify if I have
Problems in my SOA
Governance framework?

39. 39
Quality of execution

Bad one
– No planning and coordination of service projects
– Single-use services and point-to-point
connections
– Change Management issues

40. 40
Quality of execution

Good one
– Well scoped, recognisable business benefits
– Sharing of services & data types
– Ability to recognise issues early

41. 41
Looks like Registry/Repository
is a key concept..

42. 42
Registry/Repository
 Service configurations
– wsdl

Server configurations
– jboss.xml
– server.xml

Deployable artifacts
– jar,aar,ear,war,etc..

Meta data related to implementations
– hibernate-config.xml
– jaxb-mappings.xml

43. 43
So.. what does WSO2 has
to offer in this space?

44. 44

Looks like service is a key
component in SOA...

50. 50
Service in SOA
 Heart of SOA
 Life cycle
– Designed
– Developed
– QA passed
– In Production
 Metadata
– WSDL
– Schema
– Policy
 Publish & Discovery

If I use WSO2 Governance Registry,
what are the recommended deployment
Architectures? ..

Deployment Architecture 2

72. 72
Are there patterns associated with
SOA Governance?

73. 73
Patterns – Compatible Change
• Problem - Changing an already-published
service contract can impact and invalidate
existing consumer programs.

74. 74
Patterns – Compatible Change

75. 75
Patterns – Compatible Change

76. 76
Pattern – Version Identification

Problem - When an already-published service
contract is changed, unaware consumers will
miss the opportunity to leverage the change or
may be negatively impacted by the change.

77. 77
Pattern – Version Identification

78. 78
Pattern – Version Identification

79. 79
Pattern – Proxy Capability

Problem - How can a service subject to
decomposition continue to support consumers
affected by the decomposition?

80. 80
Pattern – Proxy Capability

81. 81
Pattern – Proxy Capability

82. 82
Pattern – Distributed Capability

Problem - How can a service preserve its
functional context while also fulfilling special
capability processing requirements?

83. 83
Pattern – Distributed Capability

84. 84
Pattern – Distributed Capability

85. 85
Pattern – Termination Notification

Problem - How can the scheduled expiry of a
service contract be communicated to
consumer programs?

86. 86
Pattern – Termination Notification

87. 87
Pattern – Termination Notification
