The downsides of Red Hat Fuse that I encountered were related to the Java virtual machine I worked with, which was Oracle, as the client did not create good services. In the integration, they had many steps with a loop and several bad uses of the integration with many steps and a bad pattern of design. That was the problem, and then I resolved that. The user interface is not good, and it is a very technical tool. In comparison with other tools such as Oracle Integration Cloud or Oracle BPEL, Red Hat Fuse is more complex. However, the integration in low code is more simple because there is the possibility to create services directly in Java and call them at a high level from Apache Camel and expose them with Red Hat Fuse.
