ejabberd is a free and open source instant messaging server written in
ejabberd is cross-platform, distributed, fault-tolerant, and based on open standards to achieve real-time communication.
ejabberd is designed to be a rock-solid and feature rich XMPP server.
ejabberd is suitable for small deployments, whether they need to be scalable or not, as well as extremely large deployments.
ejabberdruns under Microsoft Windows and Unix derived systems such as Linux, FreeBSD and NetBSD.
Distributed: You can run
ejabberdon a cluster of machines and all of them will serve the same Jabber domain(s). When you need more capacity you can simply add a new cheap node to your cluster. Accordingly, you do not need to buy an expensive high-end machine to support tens of thousands concurrent users.
Fault-tolerant: You can deploy an
ejabberdcluster so that all the information required for a properly working service will be replicated permanently on all nodes. This means that if one of the nodes crashes, the others will continue working without disruption. In addition, nodes also can be added or replaced ‘on the fly’.
ejabberdis built on top of the Erlang programming language. As a result, if you wish, you can perform self-contained deployments. You are not required to install an external database, an external web server, amongst others because everything is already included, and ready to run out of the box.
