Hosting multiple sites

[Jens Páll Hafsteinsson]

Hi

Can Crossbar.io's web server host multiple sites?

Please note that I'm not referring to multiple realms but rather multiple domain names like www.example1.com, www.example2.com etc.

I'm toying with the idea of replacing my nginx server with Crossbar.io.

Thanks,

JP

Hi Jens,

not a definitive answer by any means: as far as I can see, Crossbar.io Web services can be on different ports, but DNS only allows routing to IPs (see e.g this serverfault question). You would need to find a way to redirect the requests to different ports.

Regards,

Alex

Yeah, that's what I'm currently doing using nginx, that is, using it as a proxy that routes domain names to different backend servers.

Thanks for the answer Alexander.

Hi Jens,

if you mean what's know in Web servers as "named virtual hosting", then
please see

Yes, I'm referring to named virtual hosting.

I wouldn't classify this as feature creep since I consider this feature a must have in any serious HTTP server if it is to be usable in any sizable production environment. In such an environment you rarely manage only one domain and I really hate having to proxy things through nginx or something similar - it complicates the setup and adds overhead (albeit small in the case of nginx). Running multiple Crossbar servers is also wasteful of resources given that the same can be done using only one server.

On the other hand it can be advantageous to have multiple servers at the backend to partition the services you offer, since having them all on one server means all go down if one fails (or needs to be taken down because of maintenance). Your customers/users wont like that. In this case I would prefer having the same technical architecture all the way through, meaning I have a Crossbar front end server that can handle all of my domains and separate Crossbar servers connected to the front end server providing the needed services. If virtual hosting will be implemented then it might be better to wait until routing between multiple Crossbar servers has been implemented.

Still, as you mentioned Tobias, if this is as easy to implement using Twisted as you say, then it gets my vote to put this among the next things to do on the roadmap.

Thanks,
