I am interested in using Jabber in a large distributed environment. I already have a multi-tiered architecture that is used for software delivery and supports a user base of approx. 200,000 users. It consists of 3 tiers, 1 Central server 10 2nd tier servers that are located at network access points. All are hidden behind a single DNS Round Robin. 400+ 3rd tier servers that are located at client locations. User to server ratio is limited to a max of 1000 to 1. All current clients and servers are wintel, and run JRE 1.3.1. Servers are a minimum of Dual PIII 500 with 512MB Ram. In the future clients and servers will also be run on an assortment of unix flavors so Java is an absolute must.
For software distribution, clients contact the 2nd Tier, and are redirected to the best available 3rd tier servers automatically based on network subnet. This assignment information is stored on the client machine and would be available for my Jabber client. This being the case, there would be no problem handling the redirection, load balancing, or fail over from the client perspective. This approach is old hat for us and has proven to be a very reliable approach for gathering data and sending it upstream, or downloading and installing code updates. What I am contemplating is using Jabber to provide real time presence data, as well as a method for delivery of commands to the remote clients from a central location. The client portion of this looks very straightforward and I see little problem with coding a client in java to facilitate this portion of the project. The server portion however does not look so straight forward. There seems to be no Java based server components other than for web servers. Also there seems to be little information about use of Jabber in a distributed environment such as this. Thus far I have found little detailed information on server 2 server communications, or how client information is stored, or how the one would go about locating clients that are nested several servers deep. Any thoughts or feedback on this project would be greatly appreciated.
