Lorin Hochstein, Rene Moser
Automatyzacja zarządzania konfiguracją i proste instalowanie systemów Zarządzanie konfiguracją oprogramowania w systemach sieciowych jest niebanalnym zadaniem. Nawet zwykła aktualizacja czy wdrożenie nowego oprogramowania mogą się skończyć katastrofą, zwłaszcza w przypadku serwerów pracujących pod kontrolą systemów Linux czy Unix. Konieczność pilnowania ustawień w wielu różnych plikach konfiguracyjnych, z których każdy służy innemu elementowi, sprawia, że problemy mogą sprawiać nawet zasadniczo nieskomplikowane czynności - chyba że konfiguracja i wdrażanie oprogramowania w systemie zostaną zautomatyzowane za pomocą odpowiedniego narzędzia, na przykład Ansible. Istnieje wiele narzędzi do zarządzania konfiguracją oprogramowania. Spośród nich Ansible wyróżnia się szczególnymi zaletami: ma minimalne rozmiary, nie wymaga instalowania czegokolwiek na serwerach i jest proste w użyciu. Dzięki tej książce szybko nauczysz się korzystać z najnowszej wersji Ansible do instalowania nowego kodu aplikacji w środowisku produkcyjnym czy też do lepszego i prostszego zarządzania rozbudowanymi systemami. Zapoznasz się między innymi z oprogramowaniem Ansible Tower, a także dowiesz się, jak skutecznie zarządzać komputerami z systemem Windows i sprzętem sieciowym. Ten niezwykle praktyczny podręcznik powinien stale być pod ręką każdego administratora systemu, wdrożeniowca i programisty! W tej książce między innymi: Ansible a inne narzędzia do zarządzania konfiguracją systemów Scenariusze w języku YAML Testowanie i skalowanie scenariuszy Techniki wdrażania aplikacji w systemie Automatyzacja konfigurowania urządzeń sieciowych Wdrażanie aplikacji w chmurze Ansible: skuteczne narzędzie najlepszych adminów! Lorin Hochstein jest starszym inżynierem oprogramowania w Netfliksie, w zespole zajmującym się inżynierią chaosu. Wcześniej pracował jako inżynier w SendGrid Labs, główny architekt usług chmurowych w Nimbis Services. Obronił doktorat w dziedzinie informatyki na Uniwersytecie Maryland. Rene Moser jest inżynierem systemów. Od lat angażuje się w projekty open source takie jak ASF CloudStack. Od 2016 roku jest członkiem projektu Ansible Core.

Apache Camel is a de-facto standard for developing integrations in Java, and is based on well-understood Enterprise Integration Patterns. It is used within many commercial and open source integration products. Camel makes common integration tasks easy while still providing the developer with the means to customize the framework when the situation demands it. Tasks such as protocol mediation, message routing and transformation, and auditing are common usages of Camel. Apache Camel Developer's Cookbook provides hundreds of best practice tips for using Apache Camel in a format that helps you build your Camel projects. Each tip or recipe provides you with the most important steps to perform along with a summary of how it works, with references to further reading if you need more information. This book is intended to be a reliable information source that is quicker to use than an Internet search. Apache Camel Developer's Cookbook is a quick lookup guide that can also be read from cover to cover if you want to get a sense of the full power of Apache Camel. This book provides coverage of the full lifecycle of creating Apache Camel-based integration projects, including the structure of your Camel code and using the most common Enterprise Integration patterns. Patterns like Split/Join and Aggregation are covered in depth in this book. Throughout this book, you will be learning steps to transform your data. You will also learn how to perform unit and integration testing of your code using Camel's extensive testing framework, and also strategies for debugging and monitoring your code. Advanced topics like Error Handling, Parallel Processing, Transactions, and Security will also be covered in this book. This book provides you with practical tips on using Apache Camel based on years of hands-on experience from hundreds of integration projects.

The Search tool is a very powerful for any website. No matter what type of website, the search tool helps visitors find what they are looking for using key words and narrow down the results using facets. Solr is the popular, blazing fast, open source enterprise search platform from the Apache Lucene project. It is highly scalable, providing distributed search and index replication, and it powers the search and navigation features of many of the world's largest websites.This book is a practical, hands-on, end-to-end guide that provides you with all the tools required to build a fully-featured search application using Apache Solr and PHP. The book contains practical examples and step-by-step instructions.Starting off with the basics of installing Apache Solr and integrating it with Php, the book then proceeds to explore the features provided by Solr to improve searches using Php. You will learn how to build and maintain a Solr index using Php, discover the query modes available with Solr, and how to use them to tune the Solr queries to retrieve relevant results. You will look at how to build and use facets in your search, how to tune and use fast result highlighting, and how to build a spell check and auto complete feature using Solr. You will finish by learning some of the advanced concepts required to runa large-scale enterprise level search infrastructure.

Building modern apps and services with C# and .NET isn’t just about knowing the syntax—it’s about knowing the right tools for the job. Whether you’re building for web, desktop, or mobile, the .NET ecosystem offers a vast range of technologies. But with so many choices, it’s easy to get stuck in a narrow skillset. Apps and Services with .NET 10 helps you build real-world experience across the breadth of what .NET has to offer.This edition covers practical implementations across a diverse set of technologies. You'll build APIs with ASP.NET Core Minimal API, gRPC, GraphQL, and SignalR, and create user-facing applications using Blazor for the web, Avalonia for desktop, and .NET MAUI for mobile. You’ll also explore native AOT (Ahead-of-Time) compilation for high-performance web services, along with caching, messaging, and long-running background tasks. Each chapter provides hands-on projects and real-world context for when and why to use each tool.By the end, you’ll have a full-stack command of modern .NET. You’ll know how to select the right UI tech for your target platform, build APIs that scale, architect reliable backend services, and confidently adopt newer patterns.

Serverless computing has emerged as a mainstream paradigm in both cloud and on-premises computing, with AWS Lambda playing a pivotal role in shaping the Function-as-a-Service (FaaS) landscape. However, with the explosion of serverless technologies and vendors, it has become increasingly challenging to comprehend the foundational services and their offerings.Architecting Cloud Native Serverless Solutions lays a strong foundation for understanding the serverless landscape and technologies in a vendor-agnostic manner. You'll learn how to select the appropriate cloud vendors and technologies based on your specific needs. In addition, you'll dive deep into the serverless services across AWS, GCP, Azure, and Cloudflare followed by open source serverless tools such as Knative, OpenFaaS, and OpenWhisk, along with examples. You'll explore serverless solutions on Kubernetes that can be deployed on both cloud-hosted clusters and on-premises environments, with real-world use cases. Furthermore, you'll explore development frameworks, DevOps approaches, best practices, security considerations, and design principles associated with serverless computing.By the end of this serverless book, you'll be well equipped to solve your business problems by using the appropriate serverless vendors and technologies to build efficient and cost-effective serverless systems independently.
