This booklet explores the diverse aspects of RESTful services implementation using Quarkus, the most recent and modern Kubernetes-native Java framework. Starting with a historical perspective on REST (*Representational State Transfer*) architecture, which originated from Roy Fielding's doctoral dissertation in 2000, the booklet examines how this 25-year-old architectural style continues to evolve and present challenges in today's software development landscape. Despite REST's long-standing presence in the industry and its widespread adoption, developers still encounter various complexities and nuances in implementing RESTful services effectively. The booklet aims to shed light on different approaches and patterns for building RESTful services using Quarkus, demonstrating how this cutting-edge framework addresses common challenges while maintaining compliance with REST principles.
Through practical examples and real-world scenarios, the booklet illustrates the various "shades" or aspects of RESTful service implementation, from basic CRUD operations to more sophisticated patterns, like asynchronous processing reactive capabilities, efficient resource utilization, and cloud-native features, such that to leverage and build modern, scalable RESTful services that meet today's performance and architectural demands.
