4. Thomas Erl, Author of SOA:Principles of Service Design
“It's tough to incrementally adopt SOA when you're delivering
services tactically because each tactically delivered service
essentially becomes legacy once SOA is properly adopted.”

8. SOA Enablers
SOA Benefit Enabler
1) Standards-based Interfaces
Interoperability 2) Available through standard protocols
3) Canonical Data Models (within Domain/ Enterprise)
1) Assemble rather than build
Ease and Speed of 2) Processes, Rules, Events captured in high-level models instead
Development of in code
3) Service portfolio speeds up development
Agility
1) Separation of Concerns – messaging, workflow, rules, etc.
& Reducing Impact of 2) Loose Coupling, e.g. Changes localized to service
Change implementations
Lower 3) Abstract Legacy and Proprietary Interfaces
Cost
1) Standards-based interfaces
2) Process captured in BPM/ BPEL engines
Increased Visibility
3) Events captured in CEP engine
4) Data services with standardized formats for key data assets
1) Portfolio of Services built for reuse
Reuse 2) Registry/ Repository to aid developers and architects in finding
reusable assets

16. What is a Business Service?
A business service is a software solution that provides functions related
to one or more business processes. Business services may be composed
from one or more fine-grained utility, entity or task services and are
described using business semantics.

plan, the less chance you will have of increased governance burden, overlapping services, versioning

• Large Canadian Telco • Lessons learned
• Infrastructure-to-Enterprise • Technical: Demand higher quality,
• SOA means faster time to better governed infrastructure services
production, better re-use • Organizational: Wrapping legacy
• Moderately active EA oversight services and incorporating them in a
• Challenges overcome strategic vision demonstrates the
benefits of reuse
• Technology: Setting proper
granularity for strategic services • Future enterprise-centric service plans:
wrapped around legacy services Continue top-down analysis; use vendor-
provided Web services as legacy silos
• Organizational: Instilling a culture
of service reuse • Advice: Top-down, strategic analysis is
vital for even the most tactical of projects
37. Put your company

Logo here please
• Fortune 500 Shipping Co. • Lessons learned
• Major Enterprise SOA Initiative (phased • Technical: Must design services in
roll-out over 3 years, concurrent with advance to support inevitable larger,
legacy maintenance) more complex service compositions
• $250K pilot project was valuable • Organizational: Making everyone
learning experience plus high ROI understand the strategic goals is key to
getting their support
• Enterprise Architecture team has been
central to pilot and main SOA projects • Future enterprise-centric service plans:
Establish a strong business entity service
• Challenges overcome:
layer for broad reuse and business
• Technology: Assessing maturity of alignment
Service Activity Management
• Advice: Success with SOA impossible
technologies
without successfully enforcing internal
• Organizational: Enforcing Internal design standards on a consistent basis

41. Conclusions
Tactical:
• Avoid & Manage Service Proliferation
• Involve Business Audience for Business Services
• Incrementally Adopt a SOA Methodology
• Understand the Governance Consequences - Pain Now or Pain
Later
Strategic:
• Target SOA Benefits you Need and Focus on Delivering Them
• Pick one of the three SOA Strategies Discussed
• Build Your SOA Roadmap & Manage Program as a Program
• Don’t Over or Under Govern – Avoid Dictatorship!
