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.
Oracle Java Cloud is especially appropriate for moderate to complex Java applications. Due to BYOL licensing, it is also works well when you are planning to do dev and test in-house and then deploy it on Oracle Java Cloud. It is not well suited for simple Java applications due to the cost of Oracle Java Cloud. Simple applications don't need the fully managed aspect of Oracle Java Cloud.
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.
We selected Oracle Java Cloud for its native integration with other Oracle solutions and its focus on Java applications. Overall, our experience with Oracle Java Cloud has been positive, as it has improved our efficiency, security, and scalability in developing cloud applications.
