Hey, just wanted to drop these off here:
https://github.com/velinath/trinity-ci-utils-public
This is a repository with prewritten scripts to generate a .deb for authserver/worldserver binaries and extract maps, upload everything to an Amazon S3 bucket, and then install everything on a separate application server. I implemented this using Jenkins CI (https://jenkins.io) and Amazon EC2 spot instances to keep costs down. If you have any questions, feel free to ask away or open an issue on the repository.
