Obviously, OpenJDK has a more permissive license than Oracle's JDK. Still, Amazon Corretto comes with commercial support, & since it's backed by Amazon's infrastructure, downloading a new package to install on a new laptop/system is just a breeze.

OpenJDK is comparable to Oracle Java SE in most cases and you get away with significantly lower costs. Oracle Java SE have some advantages in performance on some native platforms but in most cases the OpenJDK performance is similar or at least good enough.

The CLOUD development integrating web applications with web databases definitely needs a fast and memory-efficient platform like Eclipse OpenJ9. The garbage collector and SHARED CLASSES between processes make possible a fast response to the web client and API requests. Eclipse OpenJ9 needs better documentation to explain to the programmers the advantages over other JAVA implementations like HotSpot.

Most API related and infrastructure related tech features implemented and fabricated with OpenJDK packages and Libraries. Extensive tech configurations are still developed with this product. we would to like to continue the usage this package for our upcoming projects as well. For Data Visualization I feel OpenJDK does have much resources for making data more insightful and helpful.

IBM released the Eclipse OpenJ9 under the Eclipse Foundation and open source thinking about the need for CLOUD development efficiency. Eclipse OpenJ9 could be more suitable if want to develop an API with cloud databases like MariaDB using AWS. The memory management of Eclipse OpenJ9 makes the web performance of API faster. The capacity to run shared CLASSES in a memory partition between processes gives Eclipse OpenJ9 a design advantage over other JAVA SDK platforms.
