Virtual Threads, Structured Concurrency, and Scoped Values

Discover the exciting new APIs introduced by Java’s Project Loom. This quick guide covers all the essential concepts the Java developer needs in order to understand virtual threads, structured concurrency, and scoped values.

Authors Ron Veen and David Vlijmincx clearly explain the superiority of virtual threads, introduced in Java 21, over the traditional Java threads of the past 25 years. Then they dive into how structured concurrency streamlines interactions by treating related threads as a unified unit of work, akin to the impact of structured programming on regular programming. From there, the authors explore the third Project Loom API and scoped values, clarifying their advantages over regular ThreadLocals and providing efficient usage insights. The book concludes with an exploration of common scheduling strategies.

By the end of this book, you will have a solid understanding of the concepts behind Project Loom and will be able to immediately apply this knowledge to your own code.

Migrating to Cloud-Native technology with Jakarta EE: Transform your legacy Java EE project into a cloud native application

A pragmatic guide that will take an existing Java EE application and migrate it to the latest version of Jakarta EE and turn it into a cloud native and serverless application.

The book will start with a history of Jakarta EE. Next, we will introduce an example application that we will use throughout the book as a reference application. We will gradually upgrade this application to the latest features available in Jakarta EE. We will then show how the reader can upgrade his existing Jakarta EE application. First simply migrating the code to be compatible with the latest version. And then adapting it using the modern features.

Next, the reader will be introduced to containers and what it means to build a truly cloud-native application. This is done by bringing Eclipse Microprofile into the mix.

The next big step is moving the application from the reader's own hardware to managed hardware in the cloud. This will be done by making the application run on the Microsoft Azure cloud.

Finally, we will look at running services that run in a serverless architecture.
