Migrate from Oracle Java with Ease

For the fourth time in four years, Oracle has changed how it prices and licenses Java. Many organizations that rely on Java apps are switching from the Oracle JDK to OpenJDK and taking advantage of significant cost savings in the process. But if you have a variety of specialized Java apps, created at different times and running on different JDK versions, you may have some anxiety about making the switch.

This handy book offers a concise, fun-to-read overview of OpenJDK migration:

  • Learn the three-phase strategy for migration success
  • Simplify the migration process and avoid pitfalls with older releases
  • Learn how to evaluate support providers and reduce costs
  • Access free migration tools and templates

You’ll also get tips on how to select the right Java partner to assist with your migration and provide ongoing support, security updates, application tuning, cost reductions, and expertise.

Most of the API attack surface consists of APIs used by web and mobile applications, API-to-API traffic (such as microservice traffic), and APIs exposed to employees or partners."

Mark Stephens, IDR Solutions

“If you’re using the Oracle JDK then you need to pick this up and read it. Make sure the reasons you picked Oracle JDK are still valid, they probably aren’t. If your job includes picking  JDKs for provisioning or development, then make sure you’re familiar with the materials in the book.”
Shai Almog, DEV

The reviews are in. People love their new Java super power.
