Welcome to Wikitech. This wiki hosts documentation related to the technical infrastructure maintained by the Wikimedia Foundation as well as the Wikimedia Labs cloud computing infrastructure, the Tool Labs hosting environment, and many other technical projects such as the Beta cluster project used to validate new software before deployment to the production cluster.
The production part of this wiki, also known as Wikitech, is for internal technical documentation for the Wikimedia Foundation. Documentation is available on most aspects of the technical operations of the production server clusters as well as information on how to become involved in improving the underlying infrastructure of Wikimedia projects as volunteer.
For technical documentation of MediaWiki software, see MediaWiki.org.
Wikimedia Labs (or Labs) provides a cloud computing infrastructure powered by OpenStack for projects related to the Wikimedia movement. Much of the configuration for Labs projects is managed using OpenStackManager provided special pages on this wiki. The environment also provides auxiliary services, such as shared NFS storage, and access to live replica databases of Wikimedia Foundation wikis.
Tool Labs (or Tools) is a hosting environment for community developers working on tools and bots that help users maintain and use wikis. Tool Labs provides access to replicas of Wikimedia databases, allowing developers to easily re-use this information for analytics, bot work, or by creating tools that help editors and other volunteers in their work. The infrastructure is supported by a dedicated group of Wikimedia Foundation staff and volunteers.
All Tool Labs web applications are served through tools.wmflabs.org. The main page provides an overview of user groups. Tool Labs supersedes the "Toolserver" previously run by Wikimedia Deutschland.
The Tool Labs platform is powered by Wikimedia Labs, but this aspect is not relevant to its users.
