"See Chapter 10, Competing Consumers and Message Dispatcher." Do you want to learn how you can track asynchronous messages as they flow across distributed systems? "See Chapter 11, Message History and Message Store." Do you want to understand how a system designed using integration patterns can be implemented using Java Web services, .NET message queuing, and a TIBCO-based publish-subscribe architecture? "See Chapter 9, Interlude: Composed Messaging." Utilizing years of practical experience, seasoned experts Gregor Hohpe and Bobby Woolf show how asynchronous messaging has proven to be the best strategy for enterprise integration success. However, building and deploying messaging solutions presents a number of problems for developers. " Enterprise Integration Patterns " provides an invaluable catalog of sixty-five patterns, with real-world solutions that demonstrate the formidable of messaging and help you to design effective messaging solutions for your enterprise. The authors also include examples covering a variety of different integration technologies, such as JMS, MSMQ, TIBCO ActiveEnterprise, Microsoft BizTalk, SOAP, and XSL. A case study describing a bond trading system illustrates the patterns in practice, and the book offers a look at emerging standards, as well as insights into what the future of enterprise integration might hold. This book provides a consistent vocabulary and visual notation framework to describe large-scale integration solutions across many technologies. It also explores in detail the advantages and limitations of asynchronous messaging architectures. The authors present practical advice on designing code that connects an application to a messaging system, and provide extensive information to help you determine when to send a message, how to route it to the proper destination, and how to monitor the health of a messaging system. If you want to know how to manage, monitor, and maintain a messaging system once it is in use, get this book. 0321200683B09122003
“For software developers of all experience levels looking to improve their results, and design and implement domain-driven enterprise applications consistently with the best current state of professional practice, Implementing Domain-Driven Design will impart a treasure trove of knowledge hard won within the DDD and enterprise application architecture communities over the last couple decades.” –Randy Stafford, Architect At-Large, Oracle Coherence Product Development “This book is a must-read for anybody looking to put DDD into practice.” –Udi Dahan, Founder of NServiceBus Implementing Domain-Driven Design presents a top-down approach to understanding domain-driven design (DDD) in a way that fluently connects strategic patterns to fundamental tactical programming tools. Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations. Building on Eric Evans' seminal book, Domain-Driven Design, the author presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examples–all applicable to C# developers–and all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment. The author takes you far beyond “DDD-lite” approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD's “strategic design patterns” using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals. Coverage includes Getting started the right way with DDD, so you can rapidly gain value from it Using DDD within diverse architectures, including Hexagonal, SOA, REST, CQRS, Event-Driven, and Fabric/Grid-Based Appropriately designing and applying Entities–and learning when to use Value Objects instead Mastering DDD's powerful new Domain Events technique Designing Repositories for ORM, NoSQL, and other databases

You can build a world-class SOA infrastructure entirely using popular, andmature, open-source applications. Unfortunately, the technical documentationfor most open-source projects focuses on a specific product, the big SOA picture.You're left to your own devices to figure out how to cobble together a fullsolution from the various bits. In other words, unless you already know howMule and Tuscany work with jBPM, you're stuck. Open Source SOA shows readers how to build an entire SOA application usingopen-source technologies. It shows readers how to apply key ideas like EnterpriseService Bus (ESB) design and Business Process Management (BPM) and learnthe tools and techniques to implement them effectively. To pull everything together, the author describes real-life case studies from hisown work to tie together all the principles and practices. These hard-to-find casestudies are pure gold for the reader, as most developers keep these trade secretsto themselves. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.

Complex Event Processing (CEP) is a defined set of tools and techniques for analyzing and controlling the complex series of interrelated events that drive modern distributed information systems. This emerging technology helps IS and IT professionals understand what is happening within the system, quickly identify and solve problems, and more effectively utilize events for enhanced operation, performance, and security. CEP can be applied to a broad spectrum of information system challenges, including business process automation, schedule and control processes, network monitoring and performance prediction, and intrusion detection. "The Power of Events" introduces CEP and shows specifically how this innovative technology can be utilized to enhance the quality of large-scale, distributed enterprise systems. The book describes the challenges faced by today's information systems, explains fundamental CEP concepts, and highlights CEP's role within a complex and evolving contemporary context. After thoroughly introducing the concept, the book moves on to a more detailed, technical explanation of CEP, featuring the Rapide(TM) event pattern language, reactive event pattern rules, event pattern constraints, and event processing agents. It offers practical advice on building CEP-based solutions that solve real world IS/IT problems. Readers will learn about such essential topics as: Managing the open electronic enterprise in the "global event cloud"Process architectures and on-the-fly process evolutionEvents, timing, causality, and aggregationEvent patterns and event abstraction hierarchiesCausal event tracking and information gapsMultiple views and hierarchical viewingDynamic process architecturesThe Rapide event pattern languageEvent pattern rules, constraints, and agentsEvent processing networks (EPNs)Causal models and event pattern mapsImplementing event abstraction hierarchies Several comprehensive case studies illustrate the benefits of CEP, as well as key strategies for applying the technology. Examples include the real-time monitoring of events flowing between the business processes of collaborating enterprises, and a hierarchically organized set of event-driven views of a financial trading system. One of the case studies shows how to apply CEP to network viewing and intrusion detection. The book concludes with a look at building an infrastructure for CEP, showing how the technology can provide a significant competitive advantage amidst the myriad of event-driven, Internet-based applications now coming onto the market. 0201727897B05172002

They show Microsoft's new technologies now offer powerful foundation for tomorrow's loosely coupled, highly agile, interoperable systems. Architects and developers will discover how these new technologies can be used to transcend yesterday's RPC-centric approaches, and build fully service-oriented enterprise solutions. Schittko and Erl show how to use today's .NET service technologies with both Windows Communication Foundation (WCF) and REST, and thoroughly introduce Microsoft's important new cloud-based Azure services. Next, they walk through building several common types of services with .NET, including utility, entity, and task services; and walk through composing and orchestrating services into complete solutions. Their far-ranging coverage includes security, performance tuning, BizTalk and the Enterprise Service Bus, Business Activity Monitoring, Web Services Enhancements (WSE), and much more. To help architects and developers make the most of these technologies, SOA with .NET and Azure contains multiple examples drawn from the authors' unsurpassed personal SOA implementation experience, as well as a full chapter of case studies.
In this new book, leading practitioner Greg Young shows how to incorporate effective domain modeling throughout the software development process, designing large and complex systems so they can be built more efficiently, dynamically, and successfully. Young takes the next steps beyond the DDD principles and best practices introduced by Eric Evans in Domain-Driven Design: Tackling Complexity in the Heart of Software. One step at a time, he explains how to use DDD with Command-Query Responsibility Separation (CQRS) to select the right design solutions and make them work in the real world. System designers and architects will learn how CQRS and event sourcing can simplify construction, decentralize decision-making, and make system development more flexible and responsive. Young also shows how DDD and CQRS make it possible to coordinate larger development teams without higher levels of management maturity. To write this book, Young has drawn on his widely-praised 3-day course on CQRS, Domain Events, Event Sourcing, and DDD. He answers many of the questions course participants have raised, shows how to overcome common architectural obstacles to DDD, and guides professionals in solving the #1 problem they've encountered: translating DDD's abstract concepts into concrete solutions.
