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..

Design Time Governance

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

My organisation followsan adhoc methodology...



35

Organisational/Political Governance



36

Show me how the scenario

changes after followingall these..



37

SOA Governance applied...



38

Hmm.. looks lot cleaner..

How to identify if I have

Problems in my SOAGovernance 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/Repository

is a key concept..

R i /R i



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?

Looks like service is a key

component in SOA...

Extensibility – Most important of all..

– Governance cannot be bought, you need tocustomise it..

– BAM (Business Activity Monitoring)

– BI (Business Intelligence) gathering

– CEP (Complex Event Processing)

I want to introduce SOA Governance



67

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

practises..

Best Practises



68

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 WSO2 G R i



69

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

72

Are there patterns associated with

SOA Governance?

Patterns – Compatible Change



73

• Problem - Changing an already-publishedservice contract can impact and invalidateexisting consumer programs.




74




75

Pattern – Version Identification



76

Problem - When an already-published servicecontract is changed, unaware consumers willmiss the opportunity to leverage the change ormay be negatively impacted by the change.




77




78

Pattern – Proxy Capability



79

Problem - How can a service subject todecomposition continue to support consumersaffected by the decomposition?




80




81

Pattern – Distributed Capability



82

Problem - How can a service preserve itsfunctional context while also fulfilling specialcapability processing requirements?

Pattern – Distributed Capability



83



Pattern – Termination Notification



85

Problem - How can the scheduled expiry of aservice contract be communicated toconsumer programs?

Pattern – Termination Notification



86



How do I get started?
