I wonder if it is possible to only connect to my own Opencpu server , hosted on AWS , inside javascript. Or do I still need to call Opencpu open cloud server inside javascript anyway? Total beginner with Opencpu...
You don't need to connect to any OpenCPU cloud server if you have your own one. I have a server installed on my own computer and I even can run my OpenCPU apps offline, so I'm pretty sure about that.
