Ready to conquer software complexity? This book provides a practical introduction to Domain-Driven Design with Spring Boot, giving you the essential patterns to start building more robust and business-aligned applications. It's your clear starting point for applying DDD principles without getting bogged down in theory.

Build bulletproof Spring Boot microservices—from monolith migration to domain-driven design and event-driven patterns—while mastering the production essentials of resilience, observability, and zero‑downtime delivery. Turn complex domains into clean, scalable services with bounded contexts, aggregates, repositories, and domain events, then ship faster with rate‑limited APIs, backoff‑retries, and Kubernetes rollouts. If leading Java teams to reliable, cloud‑ready microservices is the goal, this is the hands‑on guide that gets systems into production with confidence.

Are you an experienced Java developer who wants a shortcut to the best Lambda knowledge? I've distilled my 8+ years of using Lambda and 6+ years working with some of AWS's biggest Serverless customers into a short book. If you want to improve quickly, this is the book for you.

In this whitepaper, I have outlined the architecture and implementation of a service-oriented, Java-based automation framework designed for enterprise-grade end-to-end testing. By embracing modularity, reflection-based service discovery, and cross-technology orchestration, the framework addresses real-world testing challenges in complex ecosystems that span UI layers, APIs, databases, ERP systems, and batch processes.

Get started quickly, creating applications for the Model Context Protocol (MCP) using the official MCP SDKs for Python, Java 21, and Node.js. Quickly master, all of the concepts needed in order to build MCP servers, including transport protocols, tools, resources, prompts, roots, and sampling. Learn how to get familiar with popular MCP client applications such as, Claude Desktop, Postman, and the MCP Inspector.

Learn Java the way it's used in real jobs — build a complete Student Management Application with a GUI, database, and certification at the end. No fluff, just results.

In "Kotlin 2.0 Crash Course," I speak directly to you, the developer who needs to solve problems today while laying a solid foundation for tomorrow. As you follow along, you'll learn how to install Kotlin on Linux, configure your development environment, and start writing code that compiles without hiccups. I'm thrilled to guide you through the fascinating world of variables, data types, and control structures. I'll use clear examples that immediately demonstrate how our sample app stores and manipulates tasks.

Start programming in Java from scratch - beginner friendly style.Learn coding in the IDEA IntelliJ professional IDE for Java34 theory lessons (PDF, EPUB) with 170+ executable code examples (ZIP file - course for Intellij Academy plugin)572+ diverse programming tasks: answer questions, complete code, correct syntax errors, correct code, write alternative solutions (ZIP file - course for Intellij Academy plugin)Tasks start very easy and gradually work toward medium ones, and finally the hard ones.We got you covered! All tasks come with automated tests to see if your solution is correct, but also a predefined solution which can be compared side-by-side with your solution. More complex tasks come with hints to help you solve them.If that is not enough, and you still feel confused about some task, there are 200+ explanation videos which explain the solution to medium and hard tasks step-by-step (explanation videos are sold separately).

Cansado da complexidade e lentidão no desenvolvimento Java corporativo? Quer construir aplicações cloud-native robustas, escaláveis e performáticas com mais agilidade? Este livro é seu guia essencial, direto ao ponto, para arquitetos e desenvolvedores Java experientes. Desmistificamos padrões modernos como DDD estratégico e tático, mensageria reativa (Kafka, Outbox, CDC), persistência eficiente com Panache, GraphQL para APIs flexíveis e deployment em contêineres/Kubernetes, tudo aplicado ao mundo real com Quarkus e o exemplo Sakila. Sem enrolação, focamos em Padrões e Práticas que trazem robustez e preparam seus sistemas para o futuro. Aprenda com a experiência de quem já trilhou esse caminho e ganhe a confiança para arquitetar as próximas gerações de aplicações corporativas cloud-native com Java e Quarkus. Transforme sua forma de construir software!

This book is written by a Raspberry Pi enthusiast, so, it could be hopefully interesting for other Raspberry Pi enthusiasts. Also, as it is about enterprise development, it can be eventually useful for any IT specialist dealing with enterprise applications and services.
