Static connection
Yes, one thing is good but it becomes bad, like spending a lot of time running on a system. Although no connection can cause slow execution, it gives Erlang an advantage in code substitution on a running system. It is important that because

OTP applications are usually not shared, so you can only know how to use this app through the app file, assume that the application is written by the developer in the correct way.Figure 1.1 can understand the structure of OTP applications through charts generated by APP files.
