Time to Make Something Work!

• We’ve been working with the notion of SOA for over 5 years now.

• We’ve proven that SOA can work, if you approach it correctly.

• We need to start doing, but never stop learning.

• They hype is officially over.

• Time to make something work!

What’s Going On?

• Gartner Says: “The Number of Organizations Planning to Adopt SOA for the First Time Is Falling Dramatically.”

However: • Evans Data Says: “Fifty-two percent

had SOA-based projects underway, and another 31% were planning to start SOA projects over the next 12 months.”

• Tech Target Says: “The survey found that in 2008, the number of organizations planning to adopt SOA in the next 12 months fell to 25 percent from 53 percent in 2007, but it also found that 53 percent already have SOA up and running.”

Current SOA Trends

• Moving from micro- to macro-domains.– Focus on scaling– Focus on security– Focus on sharing

• Movement to cloud computing.

• Tactical wins trump strategic value.

Moving from Micro-Domain to Macro-Domain SOA

“As large and heterogeneous enterprises reach greater SOA maturity, enterprise architects often find that different business areas or domains need different things from an enterprise-level SOA platform. Accommodating these requirements may require architects to segment their SOA platform strategy and build in an extra level of interoperability and federation between different SOA domains.”

-- Mike Gilpin, Forrester

SOASOA

So, how do I win with SOA the first time?

1. Make sure there are advocates with budgets, at the executive level.

2. Begin with architecture, not with technology.

3. Get the talent and knowledge you need now.

4. Understand that SOA is ongoing (journey not a project).

5. Focus on understanding the business.

6. Define the ROI up front, and make sure it’s there upon delivery.

7. Follow a repeatable process (later in this presentation).

8. Build your SOA with the emerging Web in mind (WOA).

9. Define incremental successes, and make sure to get there.

10. Follow everything in this presentation.

5 Things to Avoid

1. Using the wrong people.

2. Selecting the technology too early.

3. Not considering “service design.”

4. Not factoring in the business.

5. Not thinking long term, and strategic.

Using the Wrong People

• Perhaps this is something you should not outsource.

– This is architecture, not development.

– This is strategic, not tactical.

• Existing talent may not be up to speed.

– You may love your current team, but perhaps they are not up for the job.

– Make the cuts now, not later.

Selecting the Technology too Early

• Don’t “manage by magazine.”• Don’t overuse “comfort

vendors.”• Avoid VDA (vendor driven

architecture)• Business -> Requirements ->

Analysis -> Technology. Now repeat!

• Make sure to do a POC, and other testing.

• Never be afraid to toss out technology.

Not Considering “Service Design”

• Services are not applications.

• Services are not APIs.• Services are services,

and should be designed properly.

– Consider granularity.– Consider repeatable

design.– Consider testing.

Not Factoring in the Business

• Always do ROI analysis before you begin work on your SOA.

• Understand core business processes, and what needs to improve.

• Understand core business drivers, and be able to sell them within the organization.

• Make sure business analysts have input at various stages.

Not Thinking Long Term, and Strategic

• SOA has a positive impact after years, not months.

• SOA is not a development project, it’s a journey.

• SOA requires a systemic change in how you do architecture, it’s not just an instance of an architecture.

• SOA requires long term corporate commitment to be successful.
