Summary
Learn how to build cloud-native microservices with Helidon - an open-source Java framework from Oracle. This book will show you how to take full advantage of the cloud by optimizing applications with fast start times, low memory consumption, and a small disk footprint. The open-source Helidon framework provides all that, and more. Its based on Java 17, giving you full access to new code features. This book reveals how Helidon also supports modern enterprise Java standards such as MicroProfile. Plus, you'll see how Helidon lets you use GraalVM to build lightning-fast native executables, and its unique reactive layer allows you to develop efficient low-level APIs. Each chapter in the book teaches a new Helidon concept through practical examples based on real-life use-cases. Youll learn how to add observability and security to your microservices, how to work with databases, and call other services. You'll also look at all MicroProfile 5.0 platform specifications as well as some stand-alone specs such as Messaging and Long Running Actions. Best of all, everything covered in this book makes it a great study guide for the upcoming Oracle Helidon certification - the perfect way to prove your new skills to a prospective employer! You will: Package microservices using JLink and GraalVM Deploy microservices to Kubernetes Review MicroProfile 5.0 specifications in detail Understand the basics of Helidon Reactive APIs.
