I'm guessing it's a joke. Y=vertical scaling, X=horizontal scaling, Z=? scaling

  X-axis scaling: running multiple identical copies of an application behind a load balancer Y-axis scaling: splitting the application with functional decomposition (a server for account info, another for catalog, etc.) Z-axis scaling: each server runs an identical copy of the application (like X-asis) but each server is responsible for only a subset of the data - some other component of the system is responsible for routing each request to the appropriate server (Ex: sharding)

    Why not just call it sharding? There's enough jargon as it is!

      Because when you treat those three aspects of scaling as dimensions of a cube, you can visualize what it means to scale on different axes. See this diagram http://akfpartners.com/techblog/wp-content/uploads/2008/05/app_cube.png http://akfpartners.com/techblog/wp-content/uploads/2008/05/a... taken from http://akfpartners.com/techblog/2008/05/08/splitting-applications-or-services-for-scale/ http://akfpartners.com/techblog/2008/05/08/splitting-applica....

      You get to sound smart when you compel people to ask what jargon-word X means.
