    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.

    I think of a few areas when looking at Microsoft Build of OpenJDK. The first is what is your cost to run for your intended product or project, if you are strapped and fall within the supported areas of Microsoft Build of OpenJDK then it's a no brainer, Microsoft Build of OpenJDK is for you! Lastly, I think of support in the respect to running into a wall and needing a fix. It can take a while for open source tools to produce fixes that the community warrants, so again if you aren't strapped for time and haven't run into a wall and could afford to wait for fixes or relevant patches then again Microsoft Build of OpenJDK is for you. Not everyone has this luxury, but these are a few areas to think about.

    • Since it's open source, enterprise support is less than as if you are running paid like an Oracle JDK.
    • Performance is improving and is I would say on par with paid solutions, this could improve to help with growth.
    • Stability will happen over time with more contributions and fixes

    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.

    Microsoft Build of OpenJDK stacks up against Oracle JDK (paid) very well. From both a performance, implementation, library support, and collaboration aspect.
