What SOA is….

Service – a functional building block that is independent from platforms,

programming languages , and physical location (Source: Wikipedia)

Service-Orientation – design paradigm that specifies the creation of

automation logic in the form of services (Source: Wikipedia)

Architecture - SOA is an architectural strategy for enabling and automating business solutions


Why all the hype?

The SOA promise – Reuse, Flexibility, Agility

Beginning Stage Maturity Increases


Why all the hype?

The SOA promise – Reuse, Flexibility, Agility

Tipping point -Shift from creating to assembling services


SOA Use Cases•Rejuvenate Legacy Systems

•Connect to Partners, Suppliers, Customers

•Expose existing services

•Automate business processes across application silos


Layered Approach to a loosely coupled Architecture


SOA can seamlessly integrate systems and processes independent of underlying technologies and physical locations

One customer order can trigger events to numerous systems, partners, suppliers, and destinations


What SOA is NOT….

Web Services – Beware of JABOWS

Something you buy – It’s something you do!

A project – It’s a journey, an evolution

The “A” stands for Architecture!!!


Catalogue Retailer• 30 year old mainframe systems• No online presence• Lacked internal skills

Solution• Hired .Net developers to build UI• Extended mainframe through integration layer• Substantially improved revenue w/ecommerce


Loyalty Marketing Company• Outdated business processes• Slow order cycles• Declining customer satisfaction

Solution• Invested in BPMS tools and process reengineering• Built new composite UI and extended legacy• Tapped into BI tools• Huge cost savings and revenue increases


Startup Saas vendor• Needed to build open, standard product• Needed to integrate w/multiple vendors• Agility and flexibility as a competitive advantage

Solution• SOA from the ground up• Hired the right talent• Went from concept to production in 1 year• Competitors will take years to catch up


What is Governance?“Ensuring and validating that assets and artifacts within the architecture are

acting as expected and maintaining a certain level of quality.”Source: Gartner

SOA without Governance….."Doing lots of little Web services projects all over the place with no governance isn't

SOA, it's just playing.” Source: Anne Thomas Manes, Burton Group

“Without that governance, your SOA is going to spiral into chaos"

Source: Anne Thomas Manes, Burton Group

“Governance is no longer optional - it's imperative” Source: SOA World


Design-Time Governance – “Building the Airplanes”“focused on the application of policies for governing the design, development

and deployment of services and supporting artifacts. It is of primary concern to business analysts, architects, project teams and developers.”

Source: Weblayers


Run-Time Governance – “Running the Control Tower”“Continuous management and optimization of service lifecycle including

change management, SLAs, service monitoring, impact analysis, etc.”

SOA is an Architecture…You are never finished!

Successful SOA initiatives address more than Technology


SOA makes life simpler for the end users BUT…..

SOA adds complexities in IT• Testing becomes much more involved• Security requires more protection• Requires discipline and standards• Shift from coding to software

engineering


Top 10 Reasons why SOA Fails

1. Fail to explain the business value of SOA

2. Underestimate the impact of organizational change

3. Fail to secure strong executive sponsorship

4. Attempt to do SOA “on the cheap”

5. Lack the required skills to deliver SOA


Top 10 Reasons why SOA Fails

6. Poor project management

7. Think of SOA as a project not an architecture

8. Underestimate the complexity of SOA

9. Fail to implement and adhere to SOA governance

10. Let the vendors drive your architecture


Top 10 Areas to Address

1. Build Strong Business Case

2. Organizational Readiness Assessment

3. Secure strong executive support

4. Secure appropriate funding

5. Identify experienced IT leader


Top 10 Areas to Address

6. Create SOA Roadmap

7. Create Resource Plan

8. Create Training Plan

9. Develop Org. Change Mgmt Plan

10. Perform Vendor Assessment(s)


SOA is something you do, not something you buy!

SOA is an ongoing endeavour

Focus on people and change is critical

Don’t try this without experienced help

The benefits far outweigh the risks
