Zuul API Gateway in Modern Microservices
"Zuul API Gateway in Modern Microservices" Zuul API Gateway in Modern Microservices is an authoritative guide for architects, engineers, and DevOps professionals seeking to master the complexities of API management within microservices environments. The book begins with a deep exploration of microservices architecture, API gateway patterns, and the unique role Zuul plays amid leading solutions such as Kong, NGINX, and Envoy. By tracing Zuul’s evolution within the Netflix OSS ecosystem and thoughtfully contrasting it with alternative gateways, readers gain clarity on foundational concepts and common challenges encountered during gateway adoption at scale. Through comprehensive technical chapters, this work offers a detailed examination of Zuul’s core architecture, filter model, and dynamic routing strategies. Readers are led step by step through the practices of custom filter development, traffic shaping, distributed rate limiting, and advanced request transformation. Emphasis is placed on integrating service discovery, securing API entry points with modern authentication and authorization techniques, and defending against evolving threats in distributed systems. Real-world deployment patterns—including multi-cloud and multi-region topologies—ensure practical applicability for even the most demanding environments. Beyond implementation, the book provides nuanced guidance on observability, resilience engineering, and operational excellence. From distributed tracing and performance tuning to automated DevOps pipelines and regulatory compliance, every facet of API gateway strategy is addressed. Case studies from industry leaders, best practices for legacy migration, and detailed coverage of extensibility underscore Zuul’s relevance in today’s fast-paced landscape. Whether modernizing brownfield architectures or scaling mission-critical digital platforms, this book empowers you to architect, secure, and operate robust microservices gateways with confidence.
Mastering Spring Boot 2.0
Author: Dinesh Rajput
language: en
Publisher: Packt Publishing Ltd
Release Date: 2018-05-31
Learn to develop, test, and deploy your Spring Boot distributed application and explore various best practices. Key Features Build and deploy your microservices architecture in the cloud Build event-driven resilient systems using Hystrix and Turbine Explore API management tools such as KONG and API documentation tools such as Swagger Book Description Spring is one of the best frameworks on the market for developing web, enterprise, and cloud ready software. Spring Boot simplifies the building of complex software dramatically by reducing the amount of boilerplate code, and by providing production-ready features and a simple deployment model. This book will address the challenges related to power that come with Spring Boot's great configurability and flexibility. You will understand how Spring Boot configuration works under the hood, how to overwrite default configurations, and how to use advanced techniques to prepare Spring Boot applications to work in production. This book will also introduce readers to a relatively new topic in the Spring ecosystem – cloud native patterns, reactive programming, and applications. Get up to speed with microservices with Spring Boot and Spring Cloud. Each chapter aims to solve a specific problem or teach you a useful skillset. By the end of this book, you will be proficient in building and deploying your Spring Boot application. What you will learn Build logically structured and highly maintainable Spring Boot applications Configure RESTful microservices using Spring Boot Make the application production and operation-friendly with Spring Actuator Build modern, high-performance distributed applications using cloud patterns Manage and deploy your Spring Boot application to the cloud (AWS) Monitor distributed applications using log aggregation and ELK Who this book is for The book is targeted at experienced Spring and Java developers who have a basic knowledge of working with Spring Boot. The reader should be familiar with Spring Boot basics, and aware of its benefits over traditional Spring Framework-based applications.
Java 17 Backend Development
This book offers beginners and backend developers with practical guidance on developing robust server-side applications with Java 17. Each chapter is structured around hands-on examples, real-world challenges, and step-by-step solutions tailored to Java professionals aiming to elevate their expertise in backend systems. It seamlessly transitions through essential development phases, covering foundational elements like from object-oriented design and basic REST endpoints to advanced microservices architecture and container orchestration. It covers from wiring up databases with Hibernate to managing asynchronous communication with Apache Kafka and securing endpoints with Spring Security. You will explore caching strategies with Redis and diving into techniques to boost performance and reduce database load. It also covers Spring Cloud concepts like Eureka for service discovery and Config Server for centralized management, showing how microservices function cohesively. The book also covers testing and debugging topics, highlighting modern tools and practices such as JUnit, Mockito, integration tests, and distributed tracing. The book clearly encourages consistent coding standards, efficient concurrency patterns, and a layered approach for verifying logic. As the book moves forward, it clearly illustrates how to maintain code quality and automate deployment workflows using continuous integration and delivery pipelines. Towards the book's end, you will know how to run Java 17 backend applications in simple production environments, and you will be applying best practices for logging, monitoring, security, and scalability. You will witness how all of these pieces fit together in a coherent ecosystem, whether they are deploying on Tomcat or containerizing with Docker. Key Learnings Set up RESTful APIs and data mappings. Use Spring Security for robust user authentication and role-based access control. Employ Redis caching techniques to offload databases and enhance performance. Integrate Kafka to establish asynchronous, high-throughput communication among microservices. Adopt Spring Cloud tools for configuration, discovery, and gateway-based microservice architectures. Employ Docker containerization for portable deployments across environments. Construct CI/CD pipelines to automate testing, building, and delivery of microservices. Conduct thorough integration testing with real databases, brokers, and external dependencies. Use debugging tools, logs, and distributed tracing to isolate production issues. Optimize concurrency, resource usage, and monitoring to handle large-scale backend demands.
