12 Developing the SOA Reference Architecture Stages in the development of the SOA Reference Architecture: Align IT with business Develop a baseline Create Reference Architecture Create infrastructure roadmap Copyright © 2009, Oracle All rights reserved Developing the SOA Reference Architecture Several key individuals will be involved across the various planning and design stages to include: • Business executives (or IT liaisons) provide business drivers for the SOA Reference Architecture • IT executives provide IT objectives, O&G model, funding model, and project list information • Enterprise architects provide current reality and future vision architecture and roadmap guidance These activities can be categorized into four general stages: • Align IT with business • Develop a baseline • Create the SOA Reference Architecture • Create the SOA infrastructure roadmap Oracle SOA Suite 11g: Essential Concepts D - 13 Developing the SOA Reference Architecture: Align IT with Business The goal at this stage is to fully capture business needs by: • Gaining an understanding of important business drivers that affect the direction of IT • Discussing IT objectives with reference to business drivers • Discussing SOA benefits and challenges with higher-level business executives • Prioritizing SOA benefits based on business and IT drivers Copyright © 2009, Oracle All rights reserved Developing the SOA Reference Architecture: Align IT with Business The primary set of activities involved in this stage include: • Organizing a kickoff session to plan future activities • Collecting business drivers and IT objectives from all stakeholders • Discussing perceived SOA benefits and challenges • Formalizing, distributing, reviewing, and finalizing the analysis This first set of activities is used to collect business and IT drivers that affect the SOA Reference Architecture decisions related to the future vision It also serves to collect benefits and challenges that management perceives to be associated with SOA The results are factored into the SOA Reference Architecture planning sessions and listed in the SOA Reference Architecture document Oracle SOA Suite 11g: Essential Concepts D - 14 Developing the SOA Reference Architecture: Develop a Baseline The goal at this stage is to complete an assessment of your SOA readiness by cataloging and documenting the current: • IT environment, key systems, technologies, and products • SOA initiatives, service developments, and supporting infrastructure • IT organization, governance, and funding models • Level of support (or resistance) for current SOA initiatives Copyright © 2009, Oracle All rights reserved Developing the SOA Reference Architecture: Develop a Baseline The primary activities at this stage include: • Collecting information on enterprise architecture and technology • Collecting information on current and future projects • Producing an SOA assessment and readiness document The results will establish a baseline for gap analysis In order to provide a starting point for the SOA infrastructure roadmap, all key stakeholders need to obtain an understanding of the current state of IT An assortment of activities may be used to properly document information on the current enterprise architecture, infrastructure, technologies, and products, as well as IT organizational structures, governance, and project funding models This stage involves all key stakeholders, with extra emphasis on the technical staff and enterprise architects, as most information gathered pertains to areas of technology A document that provides the assessment, readiness, and “current-state” of the organization is produced, which is later used as a starting point for the infrastructure roadmap Oracle SOA Suite 11g: Essential Concepts D - 15 Developing the SOA Reference Architecture: Create SOA Reference Architecture The goal of this stage is to: • Leverage collective thought leadership to define your organization’s future SOA vision • Document the vision as your SOA Reference Architecture Copyright © 2009, Oracle All rights reserved Developing the SOA Reference Architecture: Create SOA Reference Architecture The primary activities at this stage include: • Training or mentoring employees with less SOA experience • Developing planning sessions to specify future vision architecture, principles, guidelines, infrastructure, technologies, products, and so on • Formalizing, distributing, reviewing, and finalizing the complete vision document which becomes the enterprise’s SOA Reference Architecture The goal is to establish an SOA Reference Architecture for the organization, aligned with business strategy and drivers to guide future projects toward a common SOA vision The SOA Reference Architecture is a higher level of abstraction than ordinary project architectures, as it is meant to provide guidance to all projects as opposed to being a specification for any one project The SOA Reference Architecture represents a desired future vision, approximately two to three years into the future Oracle SOA Suite 11g: Essential Concepts D - 16 Developing the SOA Reference Architecture: Create SOA Infrastructure Roadmap The goal at this stage is to: • Provide an incremental plan for achieving the future vision • Synergize efforts with current and future projects Copyright © 2009, Oracle All rights reserved Developing the SOA Reference Architecture: Create SOA Infrastructure Roadmap The primary activities at this stage include: • Performing the gap analysis relative to your current baseline • Reviewing projects for infrastructure build-out and infrastructure services construction • Mapping gaps, projects, and deliverables to roadmap phases • Producing the SOA infrastructure roadmap and distributing it to all relevant stakeholders It is important to provide a roadmap to plan the build-out of SOA infrastructure, for example, infrastructure assets, such as service bus, registry, and security products, and common infrastructure services, such as security, logging, and error handling services Certain legacy application access services may also be included, as appropriate The roadmap includes one to three current or future projects identified for deployment on the SOA infrastructure in the roadmap planning horizon The roadmap helps to drive agility through the specification of standards-based development and common reusable interfaces and helps to maximize the flexibility and reusability of existing applications and infrastructure The roadmap helps both to realize reliability, scalability, availability, and security across the enterprise and to enable the on-going management of the SOA Reference Architecture and overall SOA initiative Oracle SOA Suite 11g: Essential Concepts D - 17 SOA Governance Model It is important for an organization to have an SOA Governance model in place, in order to : • Maximize the reuse of services • Minimize the duplication of business functionality in services • Maximize the business value of services • Maximize the efficiency of creating new services or modifying existing services • Define the available services and their functionality • Clearly state what services are available and what functions they perform Copyright © 2009, Oracle All rights reserved Oracle SOA Suite 11g: Essential Concepts D - 18 Example of an SOA Governance Model SOA Steering Committee Executive Sponsorship Vision and Strategy SOA Architecture Group Execute Vision and Strategy Define and Provide Guidance SOA Architecture And Advisory Team Service Engineering Service Functional Analyst Service Development Team Service Requirements Service Development Copyright © 2009, Oracle All rights reserved Example of an SOA Governance Model The slide describes an example of an SOA Governance Model consisting of the following structures: • SOA Steering Committee: It comprises the executive stakeholders in IT delivery and provides the overall guidance for SOA adoption, including the prioritization of investment in services and the funding of the delivery of those services and the shared infrastructure on which they operate • SOA Architecture Group: This group is responsible for setting the overall technical direction for SOA adoption and for measuring compliance against that direction as services are delivered • SOA Architecture and Advisory Team: This group provides the function of spotting opportunities for building or harvesting services, for advertising the availability of services to enterprise constituent, and for monitoring compliance in the use of services • Service Functional Analyst: This group seeks to provide the link between business needs and IT development project proposals, specifically business service capabilities and definitions • Service Development Team: This group is chartered with developing services that are infrastructural in nature and that benefit the entire customer organization, spanning all of its business units Oracle SOA Suite 11g: Essential Concepts D - 19 Summary In this lesson, you should have learned how to: • Describe the SOA adoption planning activities • Identify the need for an SOA Reference Architecture • Understand the stages in the development of the SOA Reference Architecture • Define the need of SOA Governance Model Copyright © 2009, Oracle All rights reserved Oracle SOA Suite 11g: Essential Concepts D -
