Optimizing Cloud Native Java, 2nd Edition

Chapter 9. Deploying Java in the Cloud

A Note for Early Release Readers

With Early Release ebooks, you get books in their earliest form—the author’s raw and unedited content as they write—so you can take advantage of these technologies long before the official release of these titles.

This will be the 9th chapter of the final book.

If you have comments about how we might improve the content and/or examples in this book, or if you notice missing material within this chapter, please reach out to the editor at [e-mail].

One enormously useful aspect of cloud native platforms is the access to ephemeral compute and the ability to scale — but this needs to be coordinated to be useful. With these basics in place you will learn about options for release and deployment patterns. Deployment techniques are incredibly helpful when rolling out change to your JVM based processes quickly, whilst still mitigating the risk of bugs.

If you are a developer, you might be wondering if deployment of Java is really an ...
