Choosing an XMPP server

I was working lately with WebRTC. One of the biggest issues there is the signaling part.

As an option you can choose XMPP with its Jingle extension. So, naturally I was looking into a few XMPP servers. What are the requirements that I was chasing for these?

My architecture is a Java based, so I was looking into solutions based on this technology. I know that I can integrate different technologies through things like LDAP or web services, but … If I needed something custom, it would have been much easier to develop something in Java. So as a nice to have, the final solution should be extensible through some kind of plugin system. Another requirement was to be open source or at least affordable.

Taking these into account I narrowed down the list to OpenFire, Tigase, Apache Vysper and Jerry Messenger.

Apache Vysper aims to be a modular, full featured XMPP (Jabber) server. Unfortunately, it is not out-of-the-box to feature an easy installation and integration procedure. It also seems to be in a beta stage, not production ready.

Jerry Messenger has an embedded Jetty server, it can be easily configurable and it features a plugin-able system.

OpenFire seemed the most complete solution in its field. It has a very rich web admin interface, a plugin system and extensive documentation. As a bonus, it is just a web application so you can install it in your favorite web application server along with your other web applications.

Tigase claims to be the most scalable XMPP server supporting hundreds of thousands of concurrent users. It is configurable, standalone and plugin-able. Unfortunately the documentation is not as extensive.

Clearly, my preference went towards OpenFire and Tigase. But I ended up not using XMPP at all for WebRTC signaling. Why? All about it in the next article.
