Service Oriented Architecture Compass

Providing a foundation for enterprise architects on the principles of service-oriented architecture, this text offers guidance on how to begin transitioning an IT infrastructure toward the SOA model, an operation tightly integrated into business processes and operations.

Aggressively being adopted by organizations in all markets, service-oriented architecture (SOA) is a framework enabling business process improvement for gaining competitive advantage. Service-Oriented Architecture: SOA Strategy, Methodology, and Technology guides you through the challenges of deploying SOA. It demonstrates conclusively that strategy and methodology are the keys to implementing SOA and provides the methodology needed for SOA success. The book examines the role of both non-agile and agile project management techniques for deploying SOA. Its methodology applies frameworks of governance, communications, product realization, project management, architecture, data management, service management, human resource management and post implementation processes. Filled with case studies, the book shows the methodology in action. This reference benefits business managers, business analysts, and technology project managers who are serious about adopting SOA as a long-term strategy. It is also benefits those new to business process management, enterprise architecture, and information systems and need to understand SOA, its business drivers, and its methodology.

The Expert, Practical Guide to Succeeding with SOA in the Enterprise In Executing SOA, four experienced SOA implementers share realistic, proven, “from-the-trenches” guidance for successfully delivering on even the largest and most complex SOA initiative. This book follows up where the authors’ best-selling Service-Oriented Architecture Compass left off, showing how to overcome key obstacles to successful SOA implementation and identifying best practices for all facets of execution—technical, organizational, and human. Among the issues it addresses: introducing a services discipline that supports collaboration and information process sharing; integrating services with preexisting technology assets and strategies; choosing the right roles for new tools; shifting culture, governance, and architecture; and bringing greater agility to the entire organizational lifecycle, not just isolated projects. Executing SOA is an indispensable resource for every enterprise architect, technical manager, and IT leader tasked with driving value from SOA in complex environments. Coverage includes · Implementing SOA governance that reflects the organization’s strategic and business focus · Running SOA projects successfully: practical guidelines and proven methodologies around service modeling and design · Leveraging reusable assets: making the most of your SOA repository · Enabling the architect to choose the correct tools and products containing the features required to execute on the SOA method for service design and implementation · Defining information services to get the right information to the right people at the right time · Integrating SOA with Web 2.0 and other innovative products and solutions · Providing highly usable human interfaces in SOA environments

LetÕs Design On-Demand Business Model _DESCRIPTION Service-Oriented Architecture (SOA) is an architectural approach that can be shared and reused. The book proposes a service-based architecture approach to design an adaptive business model for small enterprises. It presents an ad-hoc model which is based on five layered SOA architecture that can integrate all activities comprising Supply Chain Management (SCM), Customer Relationship Management (CRM), Technical and Enterprise applications tools, and hence, it best suits the SME requirements. This book covers the challenges that SMEs face to compete with large enterprises. It also compares the proposed model with traditional ERP systems and other similar approaches. It is found that the SOA model is efficient, cost-effective, and competent with similar existing solutions. There is always a need to know the scope and size of the work involved while developing a service or deriving any application from service-based model; this book will help in determining the cost and effort for such projects. KEY FEATURES - Guide to investigate series of processes/activities (value chain activities) required in Small and Medium size Enterprises (SME). - Guide for organizations to identify which SOA infrastructure will be needed to build service-based applications for themselves. - Guide for organizations to test the SOA model in order to meet the changing on-demand business requirements and ensure high level of security and governance. - Guide to handle interoperability between different vendor infrastructures. WHAT WILL YOU LEARN The book will cover the detailed study of service-oriented model from the inception of the idea to its final implementation. You will be able to understand the basics components of service-oriented architecture. You will learn how to develop SOA based model and will realize that most of the interoperability problems visible at the conceptual level could be overcome. The successful simulation of integration among business value chain activities by using the service-oriented methodology can be served as guidelines for researchers, system designers, and system stakeholders to obtain integrated and accuracy output information.

Inhaltsangabe:Abstract: In today s companies changes happen very fast. On the one hand more and more new technologies are arising, on the other hand business processes have to change because of mergers and acquisitions, new regularities, changing customer requirements and so forth. As business processes are supported by information technology, information technology has to cope with both types of changes. From a business perspective on-demand adaptation of information technology to business is required. Service-oriented architecture (SOA) is currently discussed as an opportunity to better adapt to those changes. According to Gartner's hype cycle for emerging technologies SOA already crossed the peak and is now in the trough of disillusionment. But SOA is far from being unfashionable as it would be expected during this phase. There is still high media coverage and a lot of SOA books have been published recently or will be published during the next months. What is true, however, is that the expectations are getting more realistic and people start to think about the real benefits. This is probably due to the fact that companies experienced, that implementing an SOA is not as fast and easy as the marketing hype might have given the impression. Although the hype surrounding SOA is immense, the concept is still in its early childhood with regards to concrete implementations. According to a survey conducted by Experton Group only three percent of 110 German enterprises, all with over 100 Employees, have a SOA based solution in place. Besides high costs expected from migration to SOA the lack of SOA know-how is identified as a main reason. As the survey reveals 45 percent of the interviewed enterprises have nearly no knowledge or no knowledge about SOA at all. Another 38 percent have only basic knowledge. The lack of knowledge is confirmed by a survey from the research company Quocirca, which found out, based on a sample size of 1500, that 30 percent of respondents have absolutely no knowledge about SOA and 25 percent have only minimal knowledge. Similar results are found among enterprises using SAP software. The results of an online survey conducted by the German speaking SAP User Group (DSAG) shows that 64 percent of 344 enterprises are just a little or not at all familiar with enterprise SOA and only every fifth enterprise has developed a platform strategy. Furthermore, enterprise SOA is still a topic of the IT department, although it would be [...]
