SOA:A Business Imperative
What Customers Tell Us … Customers Tell Us• Dissatisfaction with buying experience• Increasing technology complexity and exploding
data volumes• Systems too rigid, not agile to market demands• Need to do more and more with less and less• Path to agility and ROI not always clear
Analysts and the Market Tells Us• Software industry is maturing• Trend is toward open source and low cost labor• Standards are multiplying and fragmenting• More than 75% of services will be derived
from existing applications
SOA – Promises the AnswerThe evolution of a thirty year drive towards standards-based, distributed computing and component based developmentDriven by the economics of system re-use and ubiquity of global high speed network connectivity Natural progression towards loosely coupled interacting systems – defined by standard interfaces to “services”
Host The Web Service Oriented Architecture Client / Server
Distributed Computing Era
Why is SOA so Important?Reduce IT expenses• Reuse existing application functionality• Improve developer productivity
Increase operational efficiency• Share data across departments, divisions• Automate common business processes
Develop new business opportunities• Provide new and better customer service • Respond to market changes
It’s the “IT assembly line”
IONA and its CustomersPioneered SOA

SOA Is Technology Neutral
Architecting SOA has historically meant trade-offs• CORBA – Well defined contracts, Auto-generate proxies/skeletons,
Multi-language bindings, Open standard, Enterprise QoS out of the box, CORBA required at both ends
• MQ – Low coupling, Enterprise QoS, Not designed as a service platform, Proprietary
• J2EE – No contract language, Uni-lingual, Open standard, Enterprise QoS, Large developer community, Java required at both ends
• HomeGrown – “Have it your way”, Ranges from Useless to Comprehensive, Always expensive
MQSeries Home Grown
Web services and the ESB have emerged to address these issues

WSDL - Web Services Definition Language
Major IT Improvements from SOA
Services model human and business functions•Brings technology closer to human understanding•Request list of customers•Update the customer’s order•Notify the call center operator•Transfer my funds
Services are technology independent•A “style of design” not a thing•Execute them using any combination of CORBA, WebSphere MQ,
J2EE, .NET, CICS, etc.
Services are best defined by the data they exchange
SOA Best Practices
SOA Best PracticesAssess Need for SOA
•Look at SOA in the context of the business of Enterprise in addition to the context of specific applications
•Consider SOA when Reusability and Enterprise Application Integration are Key concerns
•Establish Benefits and ROI of SOA implementation for the Enterprise
“Don’t do SOA for SOA’s sake”
SOA StrategyDevelop a SOA Strategy
For example – •Define a framework so that different
applications exposing services know precisely how to define a Service
•Enable applications to use the services offered by other applications through Web Services.
• Identify a mechanism for integration (viz: an ESB) and to search and locate services exposed by applications
SOA GuidelinesPrepare SOA Guidelines
•Develop a common view across the Enterprise and build consensus
•Prepare a Architecture “Blue Book” with Architecture principles and Reference Architecture for the enterprise
• Identify Strategic Technology Stack and model implementations
•Get buy-in from Key stakeholders•Establish Governance Model and identify
“Champion” who oversees implementation across the Enterprise
SOA RoadmapDefine SOA Roadmap
• Simple: Target less Complex activitiesService enable identified applications in one department/unitDevelop Proof-of-Concept (PoC) involving an Enterprise Service Bus
• Medium: Take on Medium ComplexityService Enable applications in multiple departments and implement Service Consumption by Clients in limited manner
• Go for the Enterprise

SOA – Key Sources of ValueNo Hub – distributed solution eliminates the costs of creating and maintaining another major server in the enterpriseReduced Maintenance – simpler architecture and standards-based technology reduces support costs and headcountAgile – systems can be modified or added with minimal cost and without disrupting deployed infrastructure
SummarySOA is a Business Imperative
costs, efficiency, enables new business• IONA was a SOA pioneer with Orbix• Continues to deliver tech-neutral SOA solutions
SOA Best Practices• Apply SOA to solve a business problem, not for its own sake• Take inventory, get buy-in, establish a Framework• Use an incremental approach
Artix Leverages Existing Assets for SOA• Plug-in architecture, broad platform support, enterprise QoS• Enables incremental, leave-and-layer approach expensive, disruptive, agile than server-based solutions
