Research about Development and Production environment

[PatrickXYS]

Given the fact that we're using one environment to serve as production env and development env, which is not maintainable.

We need to consider divide into two environments, all the new changes need to be tested on development env, then push to prod env. We'd better enforce WG follow the same way, otherwise they need to find another solution.

It will slow down the development speed but provide better availability.
