2 2 Federal Aviation Administration SOA Governance January 11, 2011 Agenda Service Oriented Architecture (SOA) Governance – Michael Confoy – SOA Architect –Definition –Governance in SOA Context –Center of Excellence SOA Governance in the National Airspace System (NAS) – Paul Jackson – SWIM Governance Team –Policies –Lifecycle Context –Center of Excellence

3 3 Federal Aviation Administration SOA Governance January 11, 2011 Governance Defined Governance is about decision making Conversely, management is making sure that the enterprises governance process is executed Governance establishes the processes to assure that the appropriate laws, policies and standards are followed Governance defines the chains of responsibility, authority, and communication, as well as the measurement and control mechanisms to enable people to carry out their roles and responsibilities There are a number of governance categories, for example: –Information Technology (IT) Governance –Enterprise Architecture (EA) Governance –SOA Governance

4 4 Federal Aviation Administration SOA Governance January 11, 2011 Governance Types Defined IT Governance –The processes that ensure the effective and efficient use of IT in enabling an organization to achieve its goals 1 EA Governance –A mechanism to ensure projects apply prescriptive guidance provided by the EA process –The process of making decisions regarding the adoption of EA content 2 SOA Governance Extends IT Governance –Specifically focused on an organizations SOA: Service Lifecycle Metadata Composite applications 1 – Gartner: Defining IT Governance: The Gartner IT Governance Supply/Demand Model, 29 March – Gartner: 2010 Enterprise Architecture Research Index: EA Governance, 15 April 2010

5 5 Federal Aviation Administration SOA Governance January 11, 2011 SOA Governance Addresses concerns such as: –Service registration –Service versioning –Service ownership –Service funding –Service modeling –Service discovery and access –Deployment of services and composite applications –Security for services –Processes and procedures to support service publishing and service validation –Documenting the approach to support service lifecycle management and service reuse –Verify that running services are the approved versions –Define mechanism to manage SLAs for services –Provide a mechanism to enable runtime service look-up

6 6 Federal Aviation Administration SOA Governance January 11, 2011 Governance Types and Components * SOA Governance by Brown, Laird, Gee, and Mitra Key SOA Governance Decisions SOA Architectural Decisions SOA Infrastructure Service Portfolio Needs Service Candidate Funding and Prioritization SOA Business and SOA IT Principles SOA GOVERNANCE Key IT Governance Decisions* IT Principles IT Architectural Decisions IT Infrastructure Business Application Needs IT Investment and Prioritization

7 7 Federal Aviation Administration SOA Governance January 11, 2011 SOA Governance in SOA Context A comprehensive approach to implement effective SOA governance that will: –Assess the current organizational context of the organization –Define a governance model that the organization will accept and embrace –Leverage tooling to make governance operational and automated –Function based on best practices, processes, principles, policies and a documented methodology Potential traps in implementing SOA governance: –SOA governance is not one size fits all –SOA governance is not driven by tools –SOA governance addresses the uniqueness of service orientation –Leverage and extend IT governance to achieve SOA governance –SOA governance requires a consistent approach

8 8 Federal Aviation Administration SOA Governance January 11, 2011 SOA Governance in SOA Context Managing service lifecycle maximizes SOA value: –Service Development Provide visibility of and access to services assets for reuse Manage asset lifecycle –Service Deployment Manage promotion of service Manage description of record for deployed services Manage metadata to support SOA runtimes Manage service relationships and interactions Enable impact analysis –Service Management Monitor service performance Manage and enforce policies

9 9 Federal Aviation Administration SOA Governance January 11, 2011 Implementing an Infrastructure for SOA Runtime Governance Runtime Governance A management framework to make the right decisions Registry and Repository Working with a registry to find and connect services, and to apply policy Registry of SOA Services ESB Working with an ESB to route messages, convert protocols, transform data formats, and handle events Security Working with an access control mechanism to ensure services are allowed to access other services Service Management While monitoring the environment to identify issues and take actions to meet service level agreements (SLAs) Locate Manage Access Route Mediate Augment Log Apply Policy

10 10 Federal Aviation Administration SOA Governance January 11, 2011 What is a SOA Center of Excellence (COE)? The focal point and the catalyst for the transformation path to SOA: –Combined logical and physical grouping of resources – human, technical and intellectual –A group of individuals recognized for their leading edge, strategically valuable knowledge, and mandated to leverage and/or make that knowledge available throughout the enterprise (process or skill based) for SOA innovation –A community of semi-permanent teams of technical specialists, or people trained in a specific SOA skill and technical competencies that are the building blocks of organizational capabilities –A functional resource pool that can be tapped by the enterprise or line of business as new projects arise which will apply SOA principles

11 11 Federal Aviation Administration SOA Governance January 11, 2011 COE is the Mechanism for SOA Governance Allows the enterprise to answer fundamental questions in relation to decision rights, process measurement, and control: –Who makes the decision, and what criteria do they use, whether a service can be accessible to other applications? –Who funds, owns, and operates shared services? –What specification and implementation standards are applied across the enterprise to assure interoperability? –How does the enterprise determine whether a service achieves expected results? –How will changes to services be managed? –Who is responsible for and how are the end-to-end availability and performance for composite business functions measured, managed, and assured?

12 12 Federal Aviation Administration SOA Governance January 11, 2011 The COE will: Establish, measure, and execute governance policies Manage the service lifecycle Measure the effectiveness of various SOA initiatives Assure best practices for SOA design are achieved: –Effective service composition –Governing orchestrated services –Designing for extensibility and reuse –Loose coupling of services to support broad interoperability when requirements change –Design of appropriate modularity and granularity of services –Encapsulating business processes into well-defined, self-contained, course- grained services –Accessing services through standardized, platform-neutral, self-describing, well-structured, and extensible messages –Separating the service interface from its implementation –Assist enterprise programs with identifying associated cost/benefits relative to an SOA implementation

14 14 Federal Aviation Administration SOA Governance January 11, 2011 System Wide Information Management (SWIM) Business as Usual Host WARP IDS/ ERIDS ATOP CIWS TFM TMA STARS/ ARTS/ TAMR ERAM ASDE ETMS Inter- Agency Today - Existing point-to-point hardwired NAS - Unique interfaces, custom designs - More point-to-point unique interfaces - Costly development, test, maintenance, CM - New decisions linked to old data constructs - Cumbersome data access outside the NAS Enterprise Management LEGEND SWIM Segment 1 SWIM Future Segment SWIM Adapter FAA Systems SWIM Compliant Non-Government Systems SWIM Compliant Government Systems Core Services via FTI TFMS CIWS TDDS ITWS WMSCR AIM TBFM DOTS ERAM CARTS/ STARS - Requires common Governance Framework

15 15 Federal Aviation Administration SOA Governance January 11, 2011 Governance for the NAS Enterprise Zeal for SOA and Web Services without Governance leads to incompatible implementations and rogue services

16 16 Federal Aviation Administration SOA Governance January 11, 2011 Why Governance? Goals –Interoperability Reduce custom code Allow common Test Suites Easy transfer of knowledge among development teams –Opportunities for Reuse Reduce redundant operations Develop once, use often Guiding Principles –Adherence to Standards –Visibility/Discoverability Straightforward way to Publish Services Easy way to find and use Services

17 17 Federal Aviation Administration SOA Governance January 11, 2011 SWIM Governance WHAT must be done –SWIM Governance Policies v1.1 –Templates for Service Contract artifacts WHO is responsible –Governance Authority Initial Service Candidate Approval by Technical Review Board (TRB) SWIM manages remainder of lifecycle for approved programs –Service Providers responsibilities documented –Service Consumers responsibilities documented HOW must they do it –Technical Standards coordinated with NAS Enterprise Architecture TV-1 Technical Standards Profile TV-2 Technical Standards Forecast –FAA Standards FAA-STD-063 XML Namespaces FAA-STD-064 Web Service Registration FAA-STD-065 Web Service Description Documents FAA-STD-066 Web Service Taxonomies –SWIM Service Lifecycle Management Processes v1.0 –SWIM Version Management Processes v1.0
