Product Description
Schon seit einiger Zeit sind die Probleme der Softwareentwicklung wie zunehmende Komplexität und Heterogenität sowie fehlende Flexibilität bekannt. Einen viel versprechenden Ansatz in Bezug auf die beschriebenen Probleme stellt die Service-orientierte Architektur (SOA) dar. Auch IT-Trends wie das steigende Interesse an Prozessorientierung und Schwerpunkverlagerung von Anwendungsprogrammierung zu Anwendungsintegration fließen hier ein. Eine aussichtsreiche Lösung im Kontext prozessorientierter Softwareentwicklung basierend auf einer SOA ist die Business Process Execution Language (BPEL). Anatoliy Babiychuk erläutert in seinem Buch ausführlich die Grundlagen des Workflow-Managements und der SOA. Nachfolgend werden die BPEL-Konzepte vorgestellt. Auch dem zunehmenden Interesse an Open Source wird in diesem Buch Rechnung getragen. Eine Übersicht über die vorhandenen Open Source-Tools und ein Vergleich des am weitesten entwickelten Open Source-BPEL-Tools mit einem kommerziellen Werkzeug (Oracle Soa Suite) bilden die Schwerpunkte dieser Arbeit. Abschließend werden auch Migrationsmöglichkeiten von BPEL-Prozessen analysiert. Das Buch richtet sich an IT-Experten und interessierte Studenten.

Business Process Execution Language: The Battle to Get BPEL “Specced In” Meets Unexpected Military Opposition

Agile organizations depend heavily on Internet technologies to help them be responsive to customer needs and requirements with customized solutions and cooperation with customers and suppliers. With the use of a structured Business Process Management approach, organizations manage to integrate methods, policies, metrics, and software tools to introduce their products to the market quickly and cost-effectively, while continuously optimizing organizational activities and processes.

Information technology is a key component of business operations. IT enables radical changes to business processes thus dramatically improving their efficiency and effectiveness through the speed, information processing capabilities and connectivity of computers and Internet technologies. Analysis and modeling tools assist organizations to devise their existing processes and optimize them as well as to test and deploy software that implements these processes.

XML (Extensible Markup Language)

One of the best Business Process Management tools is XML. XML focuses on sharing structured data across different information systems, mostly over the Internet. With the support of XML, Business Process Management systems are altering the way work-flow components are implemented and executed.Used both to encode documents and to serialize data, XML structures the information, cutting it off from any functional dependency on the software that operates on it. In doing so, XML assists in the formation of a supporting infrastructure to bond the firm’s capabilities to create, deploy, and execute the entire scope of work-flow management.

BPEL (Business Process Execution Language)

BPEL for Web Services is another Business Process Management tool. BPEL is designed and developed collaboratively by Microsoft, IBM, and BEA Systems to coordinate and synchronize Web Services so they can be engaged in collaborative and transactional behavior. The use of BPEL for the proper specification of business processes and business interaction protocols extends the Web services interaction model, enabling it to support business transactions. BPEL processes function exclusively through Web Service interfaces.

BPMN (Business Process Modeling Notation)

BPMN is another Business Process Management tool primarily aiming to provide a standard notation for drawing business processes in a work-flow. This standardized graphical notation needs to be immediately understandable by: (1) the business analysts who create and refine the processes, (2) the technical developers, who implement the processes and (3) the business managers who monitor and manage the processes. Therefore, BPMN aims to serve as common language to bridge the communication gap that occurs between the design of business processes and their implementation.

Product Description
Excellent introduction to BPEL – the business process execution language. A number of Web services orchestration / process tools are based on BPEL but hide the language behind a drag-and-drop GUI. To effectively use these tools, though, you have to understand the concepts that make up BPEL – scopes, partner links, correlation sets etc. This book likely provides the best introduction to these concepts. Examples are given in raw BPEL as well as using Oracle BPEL Manager and Microsoft BizTalk. There is coverage of advanced topics, such as correlation and convoys, a great introduction to BPEL best practices. In summary, if you are interested specifically in BPEL, this is likely the book you want to get.

Composing Service-Oriented Architecture Solutions with PHP and Open-Source ActiveBPEL

• Build Web Services with PHP
• Combine PHP Web Services into orchestrations with WS-BPEL
• Use better WS-BPEL to enable parallel processing and asynchronous communication
• Simplify WS-BPEL development with free graphical tool ActiveBPEL Designer

In Detail

When utilized within a Service-oriented Architecture (SOA), Web Services are part of a business process determining the logical order of service activities – logical units of work performed by one or more services. Today, the most popular tool for organizing service activities into business processes is Web Services Business Process Execution Language (WS-BPEL), a language defining an execution format for business processes operating on Web Services. While it is not a trivial task to define a business process definition with WS-BPEL from scratch, using a graphical WS-BPEL tool can significantly simplify this process.

Examples and practice are much more valuable than theory when it comes to building applications using specific development tools. Unlike many other books on SOA in the market, this book is not focused on architecture. Instead, through numerous examples, it discusses practical aspects of SOA and WS-BPEL development, showing you how to apply architecture in practice with the help of PHP, ActiveBPEL open-source engine, and ActiveBPEL Designer – powerful development tools available for free.

What you will learn from this book?

• Install and configure the software components required to build PHP Web Services and then combine them into WS-BPEL solutions
• Use PHP as the underlying technology for creating building blocks for SOAs
• Build data-centric services based on MySQL or Oracle Database XE
• Secure services built with PHP SOAP extension
• Combine fine-grained services built with PHP into coarse-grained ones with WS-BPEL
• Deploy WS-BPEL process services to ActiveBPEL open-source engine
• Simplify WS-BPEL development with ActiveBPEL Designer
• Implement asynchronous interactions between WS-BPEL processes

Approach

With the help of many examples, the book explains how to build Web Services with PHP, combine them into SOAs with WS-BPEL, and then deploy composite WS-BPEL-based solutions to the ActiveBPEL engine. The examples in this book are presented in a way that anyone can understand and apply.

Who this book is written for?

This book is suitable for anyone who wants to start building SOA applications using powerful tools available free of charge. It also will be useful for PHP developers willing to move towards Service-Oriented Architecture (SOA).

Readers need only a basic knowledge of SOA, BPEL, and Web Services; even a total beginner will be able to follow the examples, provided the required software components are installed on his or her computer. More experienced readers might use this book as a reference, focusing only on the chapters of interest.

SOA and WS-BPEL: Composing Service-Oriented Architecture Solutions with PHP and Open-Source ActiveBPEL

Experience has shown that the implementation and optimization of processes are the most important factors in the success of SOA projects. SOA is so valuable to businesses because it enables process optimization. In order to optimize processes, we need to know which processes are relevant and we have to understand them – something that cannot be done without business process modeling. There is a major problem with this approach – a semantic gap between the process model and the applications.

This book will show you how to fill this gap. It describes a pragmatic approach to business process modeling using the Business Process Modeling Notation (BPMN) and the automatic mapping of BPMN to the Business Process Execution Language (BPEL), which is the de-facto standard for executing business processes in SOA. The book will also cover related technologies like Business Rules Management and Business Activity Monitoring which play a pivotal role in achieving closed loop Business Process Management.

This book is for CIOs, executives, SOA project managers, business process analysts, BPM and SOA architects, who are responsible for improving the efficiency of business processes through IT, or for designing SOA. It provides a high-level coverage of business process modeling, but it also gives practical development examples on how to move from model to execution. We expect the readers to be familiar with the basics of SOA.

Product Description

An Architects and Developers Guide to BPEL and BPEL4WS

• Architecture, syntax, development and composition of Business Processes and Services using BPEL
• Advanced BPEL features such as compensation, concurrency, links, scopes, events, dynamic partner links, and correlations
• Oracle BPEL Process Manager and BPEL Designer Microsoft BizTalk Server as a BPEL server

In Detail

Web services provide the basic technical platform required for application interoperability. They do not, however, provide higher level control, such as which web services need to be invoked, which operations should be called and in what sequence. Nor do they provide ways to describe the semantics of interfaces, the workflows, or e-business processes. BPEL is the missing link to assemble and integrate web services into a real business process BPEL4WS standardizes process automation between web services. This applies both within the enterprise, where BPEL4WS is used to integrate previously isolated systems, and between enterprises, where BPEL4WS enables easier and more effective integration with business partners. In providing a standard descriptive structure BPEL4WS enables enterprises to define their business processes during the design phase. Wider business benefits can flow from this through business process optimization, reengineering, and the selection of most appropriate processes . Supported by major vendors — including BEA, Hewlett-Packard, IBM, Microsoft, Novell, Oracle, SAP, Sun, and others — BPEL4WS is becoming the accepted standard for business process management.

This book provides detailed coverage of BPEL4WS, its syntax, and where, and how, it is used. It begins with an overview of web services, showing both the foundation of, and need for, BPEL. The web services orchestration stack is explained, including standards such as WS-Security, WS-Coordination, WS-Transaction, WS-Addressing, and others. The BPEL language itself is explained in detail, with Code snippets and complete examples illustrating both its syntax and typical construction. Having covered BPEL itself, the book then goes on to show BPEL is used in context. by providing an overview of major BPEL4WS servers. It covers the Oracle BPEL Process Manager and Microsoft BizTalk Server 2004 in detail, and shows how to write BPEL4WS solutions using these servers.

Business Process Execution Language for Web Services BPEL and BPEL4WS 2nd Edition

Product Description
Ten practical real-world case studies combining business process management and web services orchestration

• Real-world BPEL recipes for SOA integration and Composite Application development
• Combining business process management and web services orchestration
• Techniques and best practices with downloadable code samples from ten real-world case studies

In Detail
Service Oriented Architecture is generating a buzz across the whole IT industry. Propelled by standards-based technologies like XML, Web Services, and SOAP, SOA is quickly moving from pilot projects to mainstream applications critical to business operations. One of the key standards accelerating the adoption of SOA is Business Process Execution Language for Web Services (BPEL).

BPEL was created to enable effective composition of web services in a service-oriented environment. In the past two years, BPEL has become the most significant standard to elevate the visibility of SOA from IT to business level. BPEL is not only commoditizing the integration market, but it is also offering organizations a whole new level of agility – ability to rapidly change applications in response to the changing business landscape. BPEL enables organizations to automate their business processes by orchestrating services within and across the firewall. It forces organizations to think in terms of services. Existing functionality is exposed as services. New applications are composed using services. Communication with external vendors and partners is through services. Services are reused across different applications. Services are, or should be, everywhere!

What you will learn from this book?

In the Packt book Business Process Execution Language for Web Services by Matjaz Juric, we learnt about the building blocks and how these technologies could be used to build a simple SOA solution. As organizations increase their SOA footprint, IT Managers, Architects, and developers are starting to realize that the impact of SOA on IT and business operations can be immense. After having gained confidence with web services, they want to take it to the next level. However, adopters are challenged with some basic questions – How do I SOA-enable my existing integration investment? Can I build flexible and agile business processes? How can I administer my SOA environment without spending a fortune? There have been various best practices defined around SOA, but to date these have been somewhat abstract and lacking a real-world basis. The IT community is looking for real-world examples; examples of how other companies are embarking on an SOA initiative and how to apply that industry learning to their own projects.

What makes this a Cookbook? After you have been exposed to the different ingredients (BPEL, WSDL, and web services), this book takes the adventure to the next level by helping you cook new recipes (SOA applications) using efficient kitchen techniques (best practices). 10 SOA practitioners have gotten together to share their SOA best practices and provide practical viewpoints to tackle many of the common problems SOA promises to solve. Their recommendations are based on projects in production; their existing projects could be your next ones. Through this process you’ll learn the techniques and gain the confidence to create and deliver the recipe that’s right for your particular situation.
