Book Description
The Ultimate Guide for Designing and Governing Web Service Contracts For Web services to succeed as part of SOA, they require balanced, effective technical contracts that enable services to be evolved and repeatedly reused for years to come. Now, a team of industry experts presents the first end-to-end guide to designing and governing Web service contracts. Writing for developers, architects, governance specialists, and other IT professionals, the authors cover the following areas: Understanding Web Service Contract Technologies Initial chapters and ongoing supplementary content help even the most inexperienced professional get up to speed on how all of the different technologies and design considerations relate to the creation of Web service contracts. For example, a visual anatomy of a Web service contract documented from logical and physical perspectives is provided, along with a chapter dedicated to describing namespaces in plain English. The book is further equipped with numerous case study examples and many illustrations. Fundamental and Advanced WSDL Tutorial coverage of WSDL 1.1 and 2.0 and detailed descriptions of their differences is followed by numerous advanced WSDL topics and design techniques, including extreme loose coupling, modularization options, use of extensibility elements, asynchrony, message dispatch, service instance identification, non-SOAP HTTP binding, and WS-BPEL extensions. Also explained is how WSDL definitions are shaped by key SOA design patterns. Fundamental and Advanced XML Schema XML Schema basics are covered within the context of Web services and SOA, after which advanced XML Schema chapters delve into a variety of specialized message design considerations and techniques, including the use of wildcards, reusability of schemas and schema fragments, type inheritance and composition, CRUD-style message design, and combining industry and custom schemas. Fundamental and Advanced WS-Policy Topics, such as Policy Expression Structure, Composite Policies, Operator Composition Rules, and Policy Attachment establish a foundation upon which more advanced topics, such as policy reusability and centralization, nested, parameterized, and ignorable assertions are covered, along with an exploration of creating concurrent policy-enabled contracts and designing custom policy assertions and vocabularies. Fundamental Message Design with SOAP A broad range of message design-related topics are covered, including SOAP message structures, SOAP nodes and roles, SOAP faults, designing custom SOAP headers and working with industry-standard SOAP headers. Advanced Message Design with WS-Addressing The art of message design is taken to a new level with in-depth descriptions of WS-Addressing endpoint references (EPRs) and MAP headers and an exploration of how they are applied via SOA design patterns. Also covered are WSDL binding considerations, related MEP rules, WS-Addressing policy assertions, and detailed coverage of how WS-Addressing relates to SOAP Action values. Advanced Message Design with MTOM, and SwA Developing SOAP messages capable of transporting large documents or binary content is explored with a documentation of the MTOM packaging and serialization framework (including MTOM-related policy assertions), together with the SOAP with Attachments (SwA) standard and the related WS-I Attachments Profile. Versioning Techniques and Strategies Fundamental versioning theory starts off a series of chapters that dive into a variety of versioning techniques based on proven SOA design patterns including backward and forward compatibility, version identification strategies, service termination, policy versioning, validation by projection, concurrency control, partial understanding, and versioning with and without wildcards. Web Service Contracts and SOA The constant focus of this book is on the design and versioning of Web service contracts in support of SOA and service-orientation. Relevant SOA design principles and design patterns are periodically discussed to demonstrate how specific Web service technologies can be applied and further optimized. Furthermore, several of the advanced chapters provide expert techniques for designing Web service contracts while taking SOA governance considerations into account. About the Web Sites www.soabooks.com supplements this book with a variety of resources, including a diagram symbol legend, glossary, supplementary articles, and source code available for download. www.soaspecs.com provides further support by establishing a descriptive portal to XML and Web services specifications referenced in all of Erl's Service-Oriented Architecture books.

Book Description
The overwhelming majority of a software system’s lifespan is spent in use, not in design or implementation. So, why does conventional wisdom insist that software engineers focus primarily on the design and development of large-scale computing systems? In this collection of essays and articles, key members of Google’s Site Reliability Team explain how and why their commitment to the entire lifecycle has enabled the company to successfully build, deploy, monitor, and maintain some of the largest software systems in the world. You’ll learn the principles and practices that enable Google engineers to make systems more scalable, reliable, and efficient—lessons directly applicable to your organization. This book is divided into four sections: Introduction—Learn what site reliability engineering is and why it differs from conventional IT industry practices Principles—Examine the patterns, behaviors, and areas of concern that influence the work of a site reliability engineer (SRE) Practices—Understand the theory and practice of an SRE’s day-to-day work: building and operating large distributed computing systems Management—Explore Google's best practices for training, communication, and meetings that your organization can use

Book Description
Most suppliers lose around 16% of their customers each year. The reason? Poor service — whether perceived or real. Any technology-based support service, whether in-house, contracted or outsourced, stands to be accused of being insensitive to the requirements of its customers (or users). Equally, customers of a support service may have unrealistic expectations of what can be reasonably provided. Service Level Agreements (SLAs) can overcome these gulfs. A Service Level Agreement can create harmony between parties and can prevent disputes between customers and suppliers. It can justify investment and identify the "right" quality of service. It can mean the difference between business success and failure. SLAs are potentially a strategic tool to align all support services (particularly IT) directly to business mission achievement. In the past, few organizations used them in this way. Armed with this book and the companion SLA FRAMEWORK, more and more businesses are now succeeding. Where are SLAs going? Increasingly business-focused. Increasingly measured in real-time. Simple documents that cover complex service infrastructures. Providing a competitive edge. Embracing penalties. The brave, who commit to tight SLAs and perform against them will win the commercial spoils. This book provides the knowledge and tools based on fifteen years of intensive development to ensure your enterprise is among the winners.

Book Description
As Grids and service-oriented architectures have evolved to a common infrastructure for providing and consuming services in research and commercial environments, mechanisms are needed to agree on the objectives and the quality of such service provision. There is a clear trend to use electronic contracts between service consumers and one or more service providers, in order to achieve the necessary reliability and commitment from all parties. Service Level Agreements (SLAs) are the means to model and manage such contracts in a unified way. Grids and Service-Oriented Architectures for Service Level Agreements, the thirteenth volume of the CoreGRID series, contains current research and up-to date solutions from research and business communities presented at the IEEE Grid 2009 Workshop on Service Level Agreements in Grids, and the Service Level Agreements in Grids Dagstuhl Seminar 2009. The contributions in this volume cover Grid environments, but also generic models for SLA management that are applicable to service-oriented systems in general, like market-economic strategies, negotiation models, or monitoring infrastructures. Grids and Service-Oriented Architectures for Service Level Agreements is designed for a professional audience composed of researchers and practitioners within the Grid community industry, and is also suitable for advanced-level students in computer science.

Book Description
This book describes the CATS RVM methodology that proposes realization and verification management as a way to establish the relationship between contract management and project and service management. The CATS RVM methodology can be applied within public and private organizations, by and for clients and suppliers. Realization and verification management is the realization of the objectives intended with the contract. It does this by proactively realizing and verifying the performance stipulated in the contract during the execution phase of a contract, managing all risks associated with the performance, setting up all delivery processes, coordinating applicable delivery management processes between client and supplier, and preparing for these activities prior to the execution phase. CATS RVM offers a methodical approach to managing contracts in project and service management. It describes the basic principles, the roles, the points of attention for the realization and verification manager in the domains of delivery management and contract management, and the recommended way of working. In addition to a description of the methodology, this book also provides a description of the most common delivery management processes in both service and project management. The CATS RVM methodology is aligned with the best practice contract management methodology CATS CM as described in the book CATS CM® version 4: From working on contracts to contracts that work. However, it can be read completely independently. Where relevant, parts of CATS CM are also described in this book. This book is suitable for anyone involved with purchase and/or sales contracts in the provision of services, products or projects. This includes project managers, service managers, facility managers, those responsible for a technical service, and those responsible for the provision of HR services. This book also contains much useful information for those who work in adjacent domains such as contract management, procurement, sales, risk management, or compliance, and anyone who is responsible for contracts in a more tactical or strategic role.
