I have a deployment question in relation to ssl certs and multiple light streamer instances hosted on the same server. For this type of implementation is it necessary to have a different ssl cert for each instance or could the same ssl cert be used for all instances running on the server? Each lightstreamer instance will have a separate dns entry e.g. LS.example.com, LS-1.example.com ...etc and will sit behind a network load balancer.
thanks

Hello Garret,
it depends on the way clients connect to the servers and to the kind of certificate you can have;
as you said that each server will have its own dns entry (and thus clients will connect to each server with its own proper name, maybe exploiting our control link mechanism) then you can use the same certificate on all the machines only if you have a wildcard cerificate, otherwise you'll need a different cerificate per each machine.
The Clustering.pdf document available in the DOCS-SDKs folder of the server distribution archive further explains all the possible combinations. (this document is not available in the Moderato edition)

Thanks Mone for the quick reply, that document is really useful, we are leveraging LB stickiness so option 2.1.A applies and as such it seems we only need the one ssl cert for parent domain. It will save some money and time requesting unnecessary certs.
