Many companies are using Erlang in their production systems:

meshes.

• The Ejabberd system, which provides an Extensible Messaging and Presence Protocol

(XMPP) based instant messaging (IM) application server.

across multicore and multiserver clusters.

• The MochiWeb library that provides support for building lightweight HTTP servers.

It is used to power services such as MochiBot and MochiAds, which serve

dynamically generated content to millions of viewers daily.

standard for high-performance enterprise messaging.
