Techopedia explains Production Server
A production server is the core server on which any website or Web application is being hosted and accessed by users. It is part of the entire software and application development environment. Typically, the production server environment, hardware and software components are exactly similar to a staging server.
Though, rather being confined to in-house usage as in a staging server, the production server is open for end-user access. The software or application must be tested and debugged on a staging server before being deployed on the production server.
