Helidon Revealed : A Practical Guide to Oracle’s Microservices Framework

This book is your comprehensive introduction to Project Helidon, Oracle’s Java-based microservices framework for building cloud-native applications. The book introduces the two flavors of Helidon—Helidon SE and Helidon MP—and shows how to quickly build applications with each one. 

The book begins by placing the Helidon framework in context and explaining the MicroProfile and Jakarta EE specifications that underlie the building of microservices-based applications. From there, you will learn about the individual components of Helidon SE and Helidon MP, and you will see examples of building applications for both flavors, and for MicroProfile and Jakarta EE. Finally, the book shows how to convert Helidon applications from Java bytecode into native binaries for instant application startup and peak performance. 

What You Will Learn

• Choose correctly between Helidon SE and Helidon MP
• Create starter applications using the Helidon SE and Helidon MP quick starts
• Create server and client applications with Helidon SE components
• Create a microservices-based application with the MicroProfile specifications
• Create a database application with the Jakarta NoSQL specification

Who This Book Is For

Java developers who create microservices applications; those interested in building such applications using the Helidon framework; and developers of microservices applications who want functionality such as native-image support through GraalVM, compatibility with MicroProfile, easy connectivity to database engines, and support for reactive development patterns
