Efficient orchestration and security features improve business processes effortlessly
JBoss ESB should focus on startup and performance as EAP is heavier than lightweight Java frameworks, which impacts microservices and cloud environments. Improvements should include faster start times and reduced memory footprints. Better cold-start performance in containers should be emphasized. Cloud-native features must be enhanced since many enterprises are shifting to Kubernetes and OpenShift, making EAP more cloud-friendly. This could include providing smaller container images, native auto-scaling support, and improved integration with cloud configuration services. Enhancing the developer experience is crucial; while the current configuration is powerful, it can be complex for newcomers. As an experienced user, I navigate it easily, but newcomers struggle due to heavy reliance on XML configuration. Transitioning to a JSON-based configuration or YAML format would be beneficial, and simplifications in clustering setup for local testing would greatly assist users.

Effective data transformation and integration in complex environments with high functionality
Something that could be improved in WSO2 Enterprise Integrator is that the problem is not a lack of capability or functionalities. The problem is that it is a very complex environment. To put your hand on this environment is a very demanding task. This is the real problem. The problem is not about the product, but about the complexity to manage, to configure, to decide what to do. I have some experience using SAP R/3. It seems to me something similar. When you have to configure a situation with a client, especially for a client not in an industrial sector, but in a service sector, it is quite usual that you are in trouble for some reason. This is always the story that I found in the implementations I have done. Maybe there are only three or four big problems, in some other cases there are more than that, but this is the situation usually. For WSO2 Enterprise Integrator, not the same, but I must say it is quite often there is a need to put together some pieces and make it work in a coordinated way.
