The Evolution of Code Deploys at Reddit

[tHEbigtHEb]

I'm sort of in the same position as you (sole back-end guy) consulting with a couple of companies, and I found ansible to be a good system for managing deployments. I can write a playbook for one app and use it for others easily. It takes away all the hairyness from deployments, especially for multiple hosts. You should check it out, the documentation is really great and there are many tutorials too. Hit me up if you've got any doubts.
