Spring Boot works. But for cloud-native applications, slow startups and high memory usage become real problems.Quarkus solves both.Practical Quarkus: From Zero to Native is a hands-on guide for Java developers who want to build microservices that start instantly, use less memory, and deploy seamlessly to Kubernetes and AWS Lambda.What you will learn:<ul><li>Create your first Quarkus REST API in under 10 minutes</li><li>Add a PostgreSQL database with Panache ORM (CRUD in 20 lines of code)</li><li>Implement validation and proper HTTP error handling (404, 400)</li><li>Configure logging for development and production environments</li><li>Build native executables with GraalVM (coming in future chapters)</li></ul> Why this book is different:Every command and code block has been tested on a real machine. No copy-paste errors. No theory overload. Just working Java code you can run today.
