Staging site

From Wikipedia, the free encyclopedia

Website development usually involves staging and production servers. The staging site is used to assemble, test and review new versions of a website before it goes into production. The staging phase of the software lifecycle is often tested on hardware that mirrors hardware used in the production environment. The development site is often different from the staging site, and provides a QA zone that is separate from the development or production environments.

Normally before deploying an updated version of software to the production environment, the update has been tested in the staging environment. The staging server will resemble the production environment where the clients can do the user acceptance testing activities.
