Eclipse OpenJ9: Java for Cloud applications
Eclipse OpenJ9 is supported by IBM. It has excellent memory performance and faster startup compared with Java HotSpot(supported by Oracle). Eclipse OpenJ9 design is optimized to comply with the memory use of the Cloud. The best feature of Eclipse OpenJ9 is CLASS SHARING. It creates a shared memory for the classes for use between processes.
- Faster startup
- Memory administration
- Shared CLASSES between processes
- Marketing to promote the advantages it provides for the CLOUD.
- Documentation to used its garbage collector effectively.
- Documentation to implement the SHARED CLASESS between processes and understand the advantages.
- Open Source Alternative to Oracle JDK supported by IBM.
- Excellent performance for CLOUD development for APIs.
- Multiplatform (LInux, Windows) Java SDK that runs in a container like Docker.
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.
