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.
It's great to develop business applications. Previously, we tried different technologies but we find it the most suitable for us. We also deploy a generic backend so we don't need to install anything new to implement new applications. This helps us to develop very fast and with very low effort.
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.
Each of the above platforms offer a specific solution. Sencha provides a complete solution that is a library of components as well as a framework to modularize your application so that it's better manageable. Once you get over the learning curve of the whole technology it's a breeze to implement new functionality within the application. We have an aggressive client who comes to us every other day with some new requirement, and sencha has been able to answer all of those without issues.
