➢ Today’s IT Challenges➢ Addressing those challenges through modernization with

SOA➢ “The Steps”

♦ Scenario

♦ Products Involved

♦ Demonstration

➢ Resources

Challenges to achieving greater value from your IT investments

Applications“We need our applications to be flexible and adaptable to rapidly

changing business needs”

People“How can we improve developer

productivity and leverage our resources across all platforms?”

Teams“Our teams on different platforms

are struggling to communicate.How do we collaborate in the

context of our work?”

Infrastructure“We are looking for a cost effective way to improve our infrastructure

efficiency and free up capacity to handle more volume”

You've heard the benefits of SOA ...

➢ Reuse: Lower development and maintenance costs

➢ Time to Market: Speed deployment of new products and services

➢ Agility: Respond more quickly to changing business and market conditions

➢ Integration: Improve collaboration across your enterprise

➢ Extensibility: Extend the value of proven legacy applications

4

... And you’ve probably heard the myths ...

➢ Choosing the right SOA vendor is do-or-die

➢ SOA’s only benefit is software reuse

➢ You can’t buy an SOA

➢ SOA is too complex and costly

➢ SOA is dead

Linking Business Design to SOA ImplementationCBMSOMA is a unified method to align business with IT

• Break down your business into components to identify strategic capabilities (e.g. Product Design)

• Map business components to business processes, then model, simulate and redesign to optimize

• Define process KPI values for service modeling

• Identify services, flows, information and rules to prioritize the service portfolio

The 5 Stages of the SOMA Lifecycle

Identification➢ Domain Decomposition (top-down)➢ Goal-Service Modeling (business goals,

KPIs)➢ Existing Asset Analysis (bottom-up)

Specification➢ Information Specification➢ Existing Asset Analysis – Fine Grained➢ Service Specification➢ Subsystem Analysis➢ Component Specification

Realization➢ Select and instantiate solution

templates and patterns➢ Technical feasibility exploration➢ Detail SOA Solution Stack➢ Realization Decisions

Implementation➢ Construction of services➢ Assembly of composite services➢ Code generation➢ Integration

Deployment ➢ User Acceptance Testing (UAT)➢ Package➢ Provision➢ Deploy

Step 1: Discover ➔ Understand what you have

Step 2: Define➔ Define your business goals as requirements

Step 3: Identify➔ Identify the set of candidate services

Step 4: Model➔ Create a services model

Step 5: Implement➔ Implement your services

Understand what you have ...

➢ Find mainframe application relationships

➢ Identify high priority applications that may be suitable for services enablement

➢ Understand and manage changes across your legacy applications before considering a modernization effort

➢ Can be used in conjunction with Rational Developer for System z for complete legacy application development and modernization efforts

DefineRational Requirements Composer & Rational RequisitePro

12

Define your business goals as requirements ...➢ Rational Requirements Composer

✔ Define requirements intuitively based on user roles

✔ Web reviews with stakeholders✔ Collaborative authoring for analysts✔ Integrates with RTC and RQM to drive higher

quality and tighter business-IT alignment

➢ Rational RequisitePro✔ Trace requirements to objectives, tests and designs ✔ Understand the impact of change✔ Know what requirements have been delivered

Identify/ModelRational SOMA 2.9 & Rational Software Architect

13

Identify your candidate services & create a services model ...➢ Rational SOMA 2.9

✔ Specifically for service solution design

✔ Set of processes and best practices based on SOMA✔ Complete set of tool mentors, guidelines and examples to help you modernize your

skills

➢ Rational Software Architect✔ Automates the R-SOMA activities with tool mentors to guide the use of service

solution design tools✔ Reduces risk of failure, costs associated with development of unnecessary services✔ Provide for increased SOA asset reusability✔ Integrates with RAM for governance, RTC for collaboration

ImplementRational Developer for System z & Rational Asset Analyzer Integration

14

Implement your services ...➢ Rational Developer for System z

✔ Tools for developing services deployable to IBM CICS®, IBM IMS™, IBM WebSphere® Application Server, and IBM DB2® Stored Procedure environments

✔ Web service development for core runtimes:

o Develop a Web service with a CICS or IMS application as the application componento Develop a comprehensive CICS Web service that collects and processes data from

terminal and nonterminal applications and Web serviceso Generate a CICS application that accesses a z/OS DB2 database, VSAM file, or QSAM

structured data file and invoke it from a comprehensive Web service

➢ Rational Asset Analyzer Integration✔ Enables access to some of the RAA functionality from inside an RD/z workspace

Client Success Stories
