Hi Steffen,

Perfect. I’ve actually done exactly the same.. 
Funny :D that’s probably why you were the first stargazer on the repository? ;-)

Although not on EC2 but internally on docker and vmware. But I have a lot of tsung load tests and also a puppet version of tigase (SPEC file etc). 
I will contribute as soon as I can with the tigase server. 
That would be awesome! There’s still much to do but I hope it improves fast. Of course an own provisioning on internal hosts is entirely possible as well. 

PS: Also remember to set stuff like limit for files, net.ipv4.ip_local_port_range, multiple IPs if any etc. Otherwise you won’t go abovee 64k sockets etc. 
Yep, this is not yet done but I know that I probably need to do it soon. Some advise there wouldn’t be bad though ;)

After making it work on Vagrant (local testing), TravisCI (automated validation of contributions) and EC2 (running the real test) I’d like to announce it publicly and invite contributors to help me (and the community as a whole).
