Wiki replicas and offerings for analysis, Tool building, and exploration. Both Cloud VPS and Toolforge can be used to access Data Services.
Wikimedia's production infrastructure is the servers, software, and data that power the real, live Wikimedia websites. It is maintained by the Wikimedia Foundation's Site Reliability Engineering team as well as other teams.
The core of the production infrastructure is a highly-configured deployment MediaWiki, our open-source wiki application, but it also contains a vast array of other applications, from Apache Traffic Server to Zookeeper.
The documentation here covers the specific details of Wikimedia's infrastructure. If you're trying to run your own MediaWiki site, see the general MediaWiki documentation at mediawiki.org.
