IDES is for reading and check in the system from learning purposes.
In a real-time environment, although technically it might be similar by the process, it would be different based on your role. Some of the learning would come only while working in a real-time environment ( e.g solving performance issues in a production system).
IDES is just for training purposes. You will understand the challenges and real hard work only through real-time experience. You can only learn in IDES and not experience anything.
