What a mess ..... :-(

How can I make this better?

14

Solution

SOA Governance can solve this problem Governance applied to 4 phases

– Architectural Governance

– Design time Governance

– Operational Governance

– Organisational/Political Governance

15

Ok.. show me how..

My organisation followsan adhoc methodology...

35

Organisational/Political Governance

36

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

37

SOA Governance applied...

38

Hmm.. looks lot cleaner..

How to identify if I have Problems in my SOA Governance framework?

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

Quality of execution

Good one– Well scoped, recognisable business benefits

– Sharing of services & data types

– Ability to recognise issues early

41

Looks like Registry/Repositoryis a key concept..

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

So.. what does WSO2 hasto offer in this space?

44

Looks like service is a keycomponent in SOA...

50

Service in SOA

Heart of SOA Life cycle

– Designed

– Developed

– QA passed

– In Production Metadata

– WSDL

– Schema

– Policy Publish & Discovery

If I am evaluating a SOA GovernanceProduct, what are the keys features/core concepts tolook for?

Extensibility– Most important of all..

– Governance cannot be bought, you need to customise it..

– BAM (Business Activity Monitoring)

– BI (Business Intelligence) gathering

– CEP (Complex Event Processing)

67

I want to introduce SOA Governanceto my organisation. Give me some bestpractises..

68

Best Practises

Establish early Organisational acceptance for Governance Communicate relentlessly Automate Govern the entire service lifecycle Anticipate mixed technologies Monitory,access & report business value Consider cross organisational boundaries

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

Are there patterns associated withSOA Governance?

73

Patterns – Compatible Change

• Problem - Changing an already-published service contract can impact and invalidate existing consumer programs.

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.
