2 2 Enterprise Architecture Operational Enterprise Architecture The ability of Enterprise Architecture to impact strategic decision making and support planning, compliance, technology and investments

3 3 Operational Enterprise Architecture An Operational Enterprise Architecture is a platform for IT and Business Process Information Operational Enterprise Architecture Portfolio ManagementBusiness ProcessesStrategy and Planning Technology

4 4 Enterprise Architecture for decision support Enterprise architecture as a platform for decision support should provide the following levels of support –Strategic –Operational –Technology

5 5 Operational Enterprise Architecture An Operational Enterprise Architecture Program should support the following areas for strategy and planning: –Strategic Planning –Portfolio Analysis –Performance Management –Technology Alignment –Standards Alignment

6 6 Operational Enterprise Architecture Enterprise Architecture should also support the following areas at operational level : Asset Analysis Business flow analysis Operational planning Transition planning

7 7 Operational Enterprise Architecture An operational Enterprise Architecture needs to document or utilize: –Business architecture and Processes –Information Technology Assets –Query Capabilities –Reporting Capabilities –Mappings to reference models

8 8 Enterprise Architecture- Technology to Business Evolution Investments Portfolio Management Standards Technology Compliance Architecture

9 9 Realization of an Operational EA Realization can be achieved by developing an Enterprise Architecture Repository that stores the following information: –IT Assets –Business Processes –Investments –People

10 10 Enterprise SOA Enterprise SOA is a blueprint for an Enterprise wide IT architecture for developing services- based, interoperable solutions

11 11 Consumer Registry Service Discover Invoke(XML/SOAP) Register Service Oriented Architecture

12 12 Enterprise Services Platform

13 13 Service Oriented Architecture Leverages highly cohesive, loosely coupled components Encapsulates business data Establishes contracts through interfaces Provides interfaces to business data

14 14 Strategy Service Oriented Architecture Planning Technology Governance SOA Key Areas

15 15 Elements of a service A service is a building block with a standard interface that is independent of implementation considerations Services are –Self contained –Loosely coupled –Support Reuse –Easily maintainable

16 16 Service patterns Everything is not a Service! Typical services can be business, workflow, data, security Service Categories –Business Services –Application Services –Infrastructure Services Security Identity management Persistence

17 17 SOA Adoption Identify existing services and business processes Identify existing service interfaces Identify information that can be encapsulated as new services Build services and support service discovery

18 18 SOA Adoption SOA Adoption should focus on: SOA Planning, governance, policies, procedures Support and deployment of shared services Support of interfaces based on standards Iterative development

19 19 Benefits of SOA The benefits of SOA are: –Reuse –Cost reduction –Flexibility –Interoperability –Platform independence

20 20 SOA Best Practices Create a roadmap and detailed plans Incorporate the SOA strategy in transition planning Utilize existing standards such as web services Develop services with the right granularity Define interfaces and categorize services Define mechanisms for discovering services

21 21 Document Current State Service Oriented Architecture Process Develop Future State Develop Strategy and Plan Document Transition Plan Roadmap, Technology, Gap Analysis IT Assets, Business Flows Project plan, resources, priorities Plan to move from Current to Future State

22 22 SOA Service Design Best Practices SOA service design considerations are: –Granularity of services –Appropriate coupling –Local or Remote –Incremental development

23 23 SOA Operational Best Practices Identify the existing Business Domain Model - Data, Systems, Functions Define the technology standards and use them across the organization – SOAP, XML, WSDL Define and identify services and relate to business processes based on data, latency Create a Registry in the organization - UDDI Security – WS Security, SAML etc Process and Governance – Interface management, Points of contact, SOA adoption across the enterprise

24 24 Abstract The development of an operational Enterprise Architecture program enables effective decision making and improved efficiency in an organization. Key decisions about technology investments, compliance and technologies can be driven through Enterprise Architecture. An operational Enterprise Architecture platform gives a high level enterprise view of assets and business processes, that can serve as a blueprint for documenting and modernizing operations and systems. Service oriented architecture (SOA) is bridging the gap between business strategists and IT architects and can result in business agility, efficient integration and reuse. SOA promotes the encapsulation and deployment of services that support an operational Enterprise Architecture program. Such distributed services can provide a high degree of flexibility for responding to changes and to support business processes. This presentation will discuss SOA best practices, methodologies and challenges. An effective operational Enterprise Architecture that incorporates SOA best practices can promote significant cost savings and can support strategic decision-making in an organization.
