DESCRIPTION Serverless architecture is about having more time to focus on code, and moving quickly. In these new architectures, traditional back-end servers are replaced with cloud functions acting as discrete singlepurpose services. With serverless compute technologies like AWS Lambda, developers can build entirely serverless platforms at scale. Serverless Architectures on AWS teaches how to build, secure and manage serverless architectures that can power the most demanding web and mobile apps. This book has many ready-made and real-world examples, code snippets, diagrams, and descriptions of architectures that can be readily applied. It describes a traditional application and its back end concerns and then shows how to solve these same problems with a serverless approach. By the end, readers will be able to reason about serverless systems and be able to compose their own systems by applying these ideas and examples. KEY FEATURES * Up-to-date with the most current platform trends * Real-world examples, code snippets, and diagrams * Learn to solve back end concerns with a serverless approach AUDIENCE This book is for all software developers interested in back end technologies. Experience with JavaScript (node.js) and AWS is useful but not required. ABOUT THE TECHNOLOGY Lambda is a compute service that executes code written in JavaScript (node.js), Python, or Java on AWS infrastructure. Source code is deployed to an isolated container that has its own allocation of memory, disk space, and CPU. Serverless architectures herald a new way of building scalable, powerful, cost-effective, and high-performing back end systems. They encourage a new way of creating applications through the use of a stateless compute service to execute code.

Learn and master the new features in the new Eclipse Jakarta Faces (formerly JavaServer Faces or JSF) web framework in this definitive guide written by two of the driving forces of the Faces project and the co-creators of the OmniFaces library. Authors Bauke Scholtz and Arjan Tijms take you through real-world examples that demonstrate how these new features are used with other APIs in Jakarta EE. You'll see the new and exciting ways Jakarta Faces applications can use to communicate between a client and a server, such as using WebSockets, invoking bean methods directly from Ajax, executing client-side JavaScript when Ajax calls complete, and more Along the way you'll broaden your knowledge of Faces components and web APIs best practices, and learn a great deal about the internals of Faces and the design decisions that have been made when building the Faces API. For example, you'll see what artefacts are now CDI injectable, how CDI changed Faces internally, and what some of the caveats are when working with the CDI versions of a Faces artefact. Furthermore, you'll build an example application from scratch. After reading The Definitive Guide to Jakarta Faces in Jakarta EE 10, you'll be ready to build your own efficient and secure web applications. What You Will Learn Leverage the new features in Jakarta Faces in Jakarta EE in your existing applications Integrate Faces and CDI Use the brand new Component Search Expression framework, which enables you to more easily locate components from your template Extend the Component Search Expression framework with your own search operators Work with the different ways of mapping requests to Faces, make your application use extension-less URLs, and programmatically inspect which resources are present in your application Master the best practices for web application development and see which are obsolete Who This Book Is For Existing JSF or Java developers who need to create a web UI. No prior knowledge of Faces is required, but the book does skew towards the more experienced developer. Concepts such as dependency injection and MVC are assumed to be known, as is a general knowledge about HTML, HTTP and other web standards.

This book provides a comprehensive and accessible introduction to knowledge graphs, which have recently garnered notable attention from both industry and academia. Knowledge graphs are founded on the principle of applying a graph-based abstraction to data, and are now broadly deployed in scenarios that require integrating and extracting value from multiple, diverse sources of data at large scale. The book defines knowledge graphs and provides a high-level overview of how they are used. It presents and contrasts popular graph models that are commonly used to represent data as graphs, and the languages by which they can be queried before describing how the resulting data graph can be enhanced with notions of schema, identity, and context. The book discusses how ontologies and rules can be used to encode knowledge as well as how inductive techniques-based on statistics, graph analytics, machine learning, etc.-can be used to encode and extract knowledge. It covers techniques for the creation, enrichment, assessment, and refinement of knowledge graphs and surveys recent open and enterprise knowledge graphs and the industries or applications within which they have been most widely adopted. The book closes by discussing the current limitations and future directions along which knowledge graphs are likely to evolve. This book is aimed at students, researchers, and practitioners who wish to learn more about knowledge graphs and how they facilitate extracting value from diverse data at large scale. To make the book accessible for newcomers, running examples and graphical notation are used throughout. Formal definitions and extensive references are also provided for those who opt to delve more deeply into specific topics.

Forget those funky robot toys that were all the rage in the '80s, XSLT (Extensible Stylesheet Transformations) is the ultimate transformer. This powerful language is expert at transforming XML documents into PDF files, HTML documents, JPEG files--virtually anything your heart desires. As useful as XSLT is, though, most people have a difficult time learning its many peculiarities. And now Version 2.0, while elegant and powerful, has only added to the confusion.

"XSLT Cookbook, Second Edition" wants to set the record straight. It helps you sharpen your programming skills and overall understanding of XSLT through a collection of detailed recipes. Each recipe breaks down a specific problem into manageable chunks, giving you an easy-to-grasp roadmap for integrating XSLT with your data and applications. No other XSLT book around employs this practical problem-solution-discussion format.

In addition to offering code recipes for solving everyday problems with XSLT 1.0, this new edition shows you how to leverage the improvements found in XSLT 2.0, such as how to simplify the string manipulation and date/time conversion processes. The book also covers XPath 2.0, a critical companion standard, as well as topics ranging from basic transformations to complex sorting and linking. It even explores extension functions on a variety of different XSLT processors and shows ways to combine multiple documents using XSLT. Code examples add a real-world dimension to each technique.

Whether you're just starting out in XSLT or looking for advanced techniques, you'll find the level of information you need in "XSLT Cookbook, Second Edition,"

This book describes a set of methods, architectures, and tools to extend the data pipeline at the disposal of developers when they need to publish and consume data from Knowledge Graphs (graph-structured knowledge bases that describe the entities and relations within a domain in a semantically meaningful way) using SPARQL, Web APIs, and JSON. To do so, it focuses on the paradigmatic cases of two middleware software packages, grlc and SPARQL Transformer, which automatically build and run SPARQL-based REST APIs and allow the specification of JSON schema results, respectively. The authors highlight the underlying principles behind these technologies-query management, declarative languages, new levels of indirection, abstraction layers, and separation of concerns-, explain their practical usage, and describe their penetration in research projects and industry. The book, therefore, serves a double purpose: to provide a sound and technical description of tools and methods at the disposal of publishers and developers to quickly deploy and consume Web Data APIs on top of Knowledge Graphs; and to propose an extensible and heterogeneous Knowledge Graph access infrastructure that accommodates a growing ecosystem of querying paradigms.
