Realizing the potential of your SOA with the IBM WebSphere Service Registry and Repository

Presenter:Job Title:

2 SOA on your terms and our expertise

WebSphere Service Registry and Repository

… a service?

A repeatable business task – e.g., check customer credit;

open new account

What is …?

… service orientation?

A way of integrating your business as linked

servicesand the outcomes that

they bring

… service oriented architecture (SOA)?

An IT architectural style that supports service orientation

… a composite application?

A set of related & integrated services that

support a business process built on an SOA



Financial transparency Business/IT alignment Process control

Gather requirements Model & Simulate Design

Discover Construct & Test Compose

Integrate People Process Information

Manage applications & services Manage identity & compliance Monitor business metrics

How are customers thinking technically about flexible IT through SOA?The SOA Lifecycle



This could become… … like this

The promise of SOA A pile of services

… and so would go the promised benefits of SOA

Without proper management and governance of your SOA…



A Registry Repository answers questions customer have about governing and managing their SOA

How do I eliminate “rogue services” and ensure control of my SOA?

How do I increase service reuse?

How do I govern services as part of my SOA?

How do I enable enforcement of policies across all internal and external services?

How do I help services interact efficiently and dynamically with each other?

How can I help my ESB execute in the right context?

How do I manage the services lifecycle?

How do I optimize service interactions to be better aligned with business process?



Why SOA Governance matters? Realize business benefits of SOA

Business process flexibility

Improved time to market

Mitigate business risk and regain control Maintaining quality of service

Ensuring consistency of service

Improved team effectiveness Measuring the right things

Communicating clearly between business and IT

Establishing decision making rights associated with IT

Establishing mechanisms and policies used to measure and control the way IT decisions are made and carried out

Extension of IT governance focused on the lifecycle of services to ensure the business value of SOA

What is IT governance?

What is SOA governance?

Proper SOA governance answers customer questions about their SOA



SOA needs a registry and repository to enable governance

Establish the Governance Need

Define the Governance Approach

Monitor and Manage the Governance Processes

service proliferation Change management for shared

A registry AND repository is needed to enable governance

Infrastructure to help organize and discover services assets, govern access and monitor service vitality

Policies for publishing, using and retiring services

Change management



What is a registry … a repository?

Repository?Stores information about the nature of service usage

Business process vitality

New value through reuse

of assets

Improved connectivity

Closer alignment of IT

to business

Business Flexibility

An integrated Registry / Repository Solution is needed govern and manage SOA for maximum value

Registry? Contains information about services such as…

• Service interfaces• Descriptions• Parameters

WebSphere Service Registry and Repository V6.0.2 is an industrial-strength tool that helps you achieve more business value from your SOA by enabling better management and governance of your services. Through its robust registry and repository capabilities and its tight integration with IBM SOA Foundation, WebSphere Service Registry and Repository can be an essential foundational component of your SOA implementation.

How it works: Publish and Find Interactions

Assembly/AdminTool

Assembly/AdminTool



(1) Search is performed for a service or mediation or policy to (re)use

(2) Development tools are used to create a new service metadata artifact

(7) The assembled service is (re) published using the Service Explorer during deployment.

(7) The assembled service is (re) published using the Service Explorer during deployment.

(6) The service is configured/wired and policy relationships are established.

(5) Search is performed for a service or mediation or policy to use

(5) Search is performed for a service or mediation or policy to use

(3) Service metadata artifact is published to the WSRR

(4) WSRR performs validation and enforces policies



How it’s used: Greater reuse of services


WebSphere Service Registry and RepositoryBusiness need for a service is initiated

Business need for a service is initiated

“Find” for availability

“Find” for availability

If the service exists… If the service exists but requires modification…

If the service does not exist…

1) Service owner contacted

2) Owner performs impact analysis

3) WSRR updated

4) Service is reused

1) Governance process initiates new service development

2) “In-progress” service is recorded in the WSRR

3) Community is notified to eliminate redundant service development

1) Service owner agrees to modify the service

2) Performs impact analysis

3) Service is altered and a new version is published (owner may also trigger a custody transfer)

4) Services asset is reused

Dynamic selectionDynamic selection



How it’s used: Enhancing Connectivity

Dynamic Endpoint Selection Availability Management Policy Enforcement

1) ESB mediation is invoked

2) Mediation queries WSRR for information about the requestor and candidate provider

3) Mediation matches requestor with best candidate provider

4) Message is routed

1) Selected provider fails to respond due to failure

2) Mediation queries WSRR to find other candidate providers

3) Mediation matches requestor with best candidate provider




+

1) Mediation queries WSRR for information about the requestor and candidate provider

2) Mediation retrieves policy information from registry

3) Requestor and provider are matched based on these policies
