All modules are under the Architecture, and it is difficult to expand the performance of one module without affecting the performance of other modules

The difference between the modules of the system is blurred the code complexity is getting higher and higher, and the cost of code modification is getting higher and higher

The underlying layer adopts a distributed system, which has high system fault tolerance, but the network delay is large

When adding new functions, it is not appropriate to choose a new framework, hindering technological innovation
