This is an overview of terminology used in technical documentation for Wikimedia Foundation infrastructure and software.
This list is meant to be a reference point for the canonical or preferred words to convey a certain concept. Avoid listing older or less common words for the same concepts.
- cluster is group of servers with a common purpose. For example: "text" Varnish cluster, "jobrunner" appserver cluster. Note that a cluster may span multiple DCs.
- data center (abbreviated DC), is a physical location in which server racks reside. For example: Esams data center as listed on Data centers. This includes both core services and cache PoPs. (Avoid "cluster".)
- directory, a file system structure in which files are stored. For example: TMPDIR or $wgExtensionDirectory. (Avoid "path", "folder" or "address".)
- file path, the absolute path on the file system to a particular file or directory.
- path, part of a URL starting from the slash after a host and optional port, until the end or any query string or hash fragment. For example: $wgExtensionAssetsPath (Avoid "folder" or "directory").
