Topic Overview: Service-Oriented Architecture by Randy Heffner and Larry Fulton with Mike Gilpin, Henry Peyret, Ken Vollmer, and Jacqueline Stone

EXECUT I V E S U M MA RY Some think of service-oriented architecture (SOA) as just Web services standards to achieve better application integration. However, SOA is gaining recognition as a key element of strategic business transformation — a much higher level of business impact than mere application integration. In their most strategic usage, SOA-based business services provide a modular, digital-world implementation of your business, ready to connect to any customer, employee, supplier, or partner wherever and whenever. SOA increases both business and application flexibility by changing your style of design, deployment, and management of applications and software infrastructure. Web services add value to SOA through a standards-based ecosystem and open access via loose technology coupling. SOA’s ability to save IT costs and build business flexibility has driven broad adoption: 62% of enterprises are using or will use SOA by the end of 2007, and 40% of enterprises are using SOA for strategic business transformation. SOA is applicable to a broad range of business scenarios, and every organization should investigate SOA to learn where and how it can benefit.

Topic Overview: Service-Oriented Architecture For Enterprise Architecture Professionals

WHY SOA MATTERS SOA matters because it improves both business results and IT results. According to data from Forrester’s Business Data Services, 55% to 70% of SOA users identified lowering business and application costs as drivers for SOA.1 Even more of them — 75% to 85% of SOA users — identified improving business and application flexibility as drivers for SOA. SOA’s improved flexibility allows you to change quickly to meet changing business demands. It’s not just industry hype, either. SOA is delivering results that make people want more of it. Current SOA users report strong satisfaction with SOA: 70% of current enterprise SOA users say that they will increase their use of SOA, while only 3% will decrease their use. In keeping with SOA’s theme of flexibility and change, you don’t have to do a massive, all-at-once conversion to get the benefits. You can implement SOA incrementally, starting with small, near-term requirements and later expanding SOA usage as other business needs arise. And you don’t have to invest heavily to build an extensive architecture before you can see real benefits. You can use SOA to leverage existing applications and infrastructure to solve business problems without having to rebuild everything from scratch. These benefits make SOA attractive to IT shops that are working to deliver business transformation and flexibility via faster, lower-cost integration and solution delivery. FORRESTER’S TAKE ON SOA With all the industry hype about Web services and SOA, some people see it as just another new technology, but that misses a very important and strategic point: SOA is first and foremost about the design of your business, not the technology. Within the design framework of SOA, each major business service performs a complete business unit of work, hiding the complexity of your IT applications behind a pluggable software interface for a specific, targeted business capability like “submit order” or “distribute sales lead.” This design framework results in better alignment between the implementation of your IT applications and the design of your business. This in turn provides strategic business value because the key to long-term success is business flexibility, and strategic implementation of SOA provides IT flexibility that lines up with the ways in which your business is likely to change. Increased business flexibility increases your chances of strategic long-term success. Strategic success may include enabling your business to rapidly adapt to global markets, competitive issues, and regulatory demands. It may include building deep customer and partner integration for end-to-end process optimization. Perhaps your strategic success needs deeper, more flexible internal business optimization that combines deeper insight into business operations with SOA’s policy-based configuration so you can quickly change and improve business operations. The largest enterprises lead the charge — by the end of 2007, Forrester expects to see 75% of Global 2000 firms implementing SOA — but even small and medium-size businesses (SMBs) are broadly adopting SOA. In addition to SOA’s strategic business benefits, SOA also applies inside of IT, optimizing application integration scenarios, extending the life of existing applications, and increasing the flexibility of many types of IT-based business solutions.

Topic Overview: Service-Oriented Architecture For Enterprise Architecture Professionals

A firm can either: 1) use SOA sporadically across a variety of projects, or 2) work to achieve a coordinated enterprisewide strategy for SOA. Enterprise adoption provides opportunity for the greatest value. Over time, leading SOA adopter firms re-architect their IT organizations around services, using SOA to incrementally transform applications and business processes in line with today’s business objectives. A strategic adoption of SOA will fundamentally change IT’s relationship with the business, leading to a service-oriented-IT (SO-IT) organization. The elements of a mature SO-IT organization include:

· A clear, compelling, concise SOA vision. · Strong business-IT collaboration. · Clear IT governance, enterprise architecture, and SOA governance practices. · A clear understanding of the critical importance of good business service designs. · Coordinated architecture and infrastructure evolution. · Incremental funding models for SOA. · Service delivery life-cycle and roles adaptations for SOA. · A library of patterns for service design and implementation. The research below will assist you on your path to SOA: how to think, where to start, why your organization should take the plunge, what to do (and what not to do), and who to talk with. Each report is tagged with a reading priority for chief information officers (CIOs), enterprise architecture professionals (EAs), and application and program management professionals (APMs). And if you have questions along the way, the Forrester Research Help Desk can assist you. THE BASICS Our basic SOA research gives you an introduction to key issues and concepts of SOA and an overview of important topics covered under the SOA umbrella. These documents cover the value of SOA to your organization, key design principles of SOA, how to best make the jump to SOA, and the difference between SOA and Web services. Reading priorities for three roles follow the list of documents (see Figure 1).

Topic Overview: Service-Oriented Architecture For Enterprise Architecture Professionals

Digital Business Architecture SOA-based business services embody your business capabilities in the digital world, but there is a much bigger and deeper tie between your business and the whole of your technology base. SOA exists in a broader context of IT architecture, and you need to invest in much more than just SOA. All too often, the connections between various architectural domains, such as user interactions, communications, and IT infrastructure, are not well understood. Yet there is power in these connections, as together, they enable a more profound, long-range strategy for transforming business and IT. Forrester’s Digital Business Architecture provides a broad, top-level, conceptual architecture into which multiple emerging architectural trends fit together into a stronger whole, enabling a more effective and flexible future for your business in the digital age — your digital business.
