Recently started the Oracle program: Are You The Smartest.
For me it is an opportunity to test my current knowledge level and to extend my knowledge.
After every session I follow, I will write a brief summary as part of the preparation for the test.
I will continue with the summary of the following session.
ARCHITECTS TRAINING – SERVICE INTEGRATION – Governance challenges in the services landscape
This 43 minutes during session was divided into the following parts:
- Challenges Solved with SOA Governance
- Oracle’s SOA Governance
- Customer Success Stories
Challenges Solved with SOA Governance
The reality: the benefits of SOA do not come automatically by implementing some webservices and a service bus.
They didn’t call it SOT for service oriented technology. They called it “Architecture” for a reason;
- It needs to be top-down vs. bottom-up
- Think Big – Start Small
- Bottom-up expresses the “how” not the “why”
- It needs to be aligned with the overall business architecture
- It’s not necessarily a project delivering an application
Lack of Governance Inhibits SOA Adoption
In traditional development you ‘know’ some important things like: budget, who’s responsible, who does what, who will use it, who will pay for it, … etc.
In SOA base development you do not know these things. Who hase to pay for using the service?, How are cost for usage calculated? …
SOA Governance definition
Governance, whether it is financial, business, legal or IT, is about getting people to do the <strong>right thing at the right time</strong>. In other words, it is about encouraging the behavior that will achieve your business goals
- SOA Governance provides the framework for planning, developing, deploying and managing the SOA environment
- Ensure alignment
- Establish controls
- Reduce cost over time
- Mitigate risks
SOA Governance in the Enterprise
SOA Governance – Why is it needed?
Without it …
- Service anarchy
- Poor services, low-reuse, lots of the wrong services, perpetuation of silos
- Business Solutions fail to use Services
- No promotion, no change in project delivery, no trust or confidence in services
- High cost of operations
- No consistency “everyone’s doing their version of SOA”
- Duplicated infrastructure, no standardisation
- No measured benefit
- No visibility of SOA Benefits
What Decisions must be Governed and Made ?
- Which services to do ?
- Which services to do first?
- Is this really a new, reusable service ?
- Who is going to pay for development and maintenance of this service?
- Who owns this service?
- What decisions needs to made for your organization to have effective SOA Governance?
- Who should make these decisions?
- How will these decisions be made and monitored?
- What Structures, Process, Communication, Tools should be deployed
These are all aspects which can be answered and managed with a SOA Governance
Oracle’s SOA Governance (Model , Enabling Technologies)
The right people do the right thing / have the right view
Governance and SOA Maturity must be in sink with each other (same level).
SOA Governance Model constituent parts…
Service Lifecycle Governance <> SOA Governance
Political/Organizational Aspects of SOA Governance Influencing SOA Behavior Mandate AND Authority
- Mandate AND Authority
- Structures must be empowered to make and enforce decisions
- SOA Organisation (if appropriate update existing structures)
- Structure with a broad set of SOA strategy, architecture and implementation skills to enable and support project delivery teams
- Not a mass IT reorganisation
- Education for all
- Specific Roles in the governance model
- Opportunities for the individual; incentives for key actors
SOA Steering Board
- Executive Sponsorship
- Set business priority – enable alignment
- Vision & Strategy
- Establish funding models
- Exeption Management
SOA Architecture Authority / Competence Center
- Strategy Execution
- Reference Architecture Authority
- SOA Skills & Resource Base
- Adjudicates architectural priorities ans issues
- Enterprise Modeling for Service Architectures
- Service Engineering Framework Compliance & Governance
- Core team supplemented by all project architects
SOA Enablement Team / COE
- Enables corporate competency development
- Compliance Assurance
- Project Enablement
- Service Engineers
SOA Governance: Tools and Infrastructure
- Single source of truth for SOA portfolio
- Provide dependency tracking and impact analysis, tracks usage and compliance for visibility into ROI
- Ensures policy compliance throughout the lifecycle and enforcement across the SOA infrastructure
- Monitors, diagnoses and ensures service levels
- Surfaces metrics and analytics for decision support
Customer Success Stories
Wachovia Investment Banking
- Like many companies, O2 found itself developing the same technical functions many times.
- Inefficiency in OPEX and CAPEX expenditure
- Longer time to market
- A complex IT architecture
- Untenable Development and maintenance of HW and SW for point solutions
Critical Success Factors & Lesson Learned
- From the outset, O2 recognized the importance of strong SOA governance and communication.
- Followed best practices in establishing architecture and service management capabilities.
- Use of the Service Factory concept for shared services.
- Establish a clear governance framework
- While you design a service in the context of a given project, try to understand if it would make sense in the context of other projects and develop it to support as many other requirements as possible
- It takes time to build a service portfolio.
- Maintain enthusiasm for the SOA approach by getting projects to deliver. Communicate and demostrate business value.
- Implement a governance framework that will guide our organization as it deploys a service-oriented operating model by developing an SOA governance roadmap that focuses on delivering the greatest value to Eaton.
- Eaton’s SOA governance model specifies the processes, policies, controls and governance mechanisms that ensure compliance within the Service Oriented Architecture.
- It additionally provides the organizational structure and defines the roles and responsibilities that are needed to operate this governance model.
The SOA Governance function will be a 3-tier structure consisting of:
- SOA Steering Commitee
- Provides guidance and direction to the SOA governance boards.
- SOA Strategy Board
- Establishes SOA-related stategies and roadmaps
- Establishes SOA-related policies and guidelines
- SOA Tactical Governance Board
- Reviews the compliance of SOA-related artifacts created by the SOA development communities within Eaton to the strategies, policies, and guidelines created by the SOA Strategy Board
- OER/OSR- oriented
Recap & Suggestions
- SOA Governance is a process and not a project, therefore measure progress and course-correct when needed
- SOA Governance requires processes, people and technology
- Incrementally Adopt a SOA Governance Model
- Build a 2 – 3 year SOA Governance vision and deploy incrementally
- SOA Governance Structures must have appropriate level of authority to make and enforce decisions
- It’s all about TRUST and COMMUNICATION
- Understand the Governance Consequences – Pain Now or Pain Later
