Beta Cluster

The [https://meta.wikimedia.beta.wmflabs.org/wiki/Main_Page Beta Cluster] is a functional, production-like environment in the Cloud VPS that is suitable for final-stage testing of new features. It runs off git master and has its MediaWiki core and extensions code updated about every ten minutes. Beta Cluster is one of the 1>m:Special:MyLanguage/Wikimedia wikis#Test wikis|Wikimedia test wikis. It does not use SUL logins, so users need to create separate accounts.


 * See the 1>:wikitech:Nova_Resource:Deployment-prep|overview of its configuration.

Rationale
The aim is to provide an exact copy of the WMF production cluster (including db hosts, apaches, logging, squids, varnish caching, image scalers, etc.) using 1>wikitech:Portal:Cloud VPS|Cloud VPS instances.

Open tasks
See the [https://phabricator.wikimedia.org/project/board/497/?order=priority workboard in Phabricator].
