This is a set of Ruby scripts, and unix service configuration files I put together in a hurry back in September to scale a then fast growing Facebook application using Amazon EC2's AutoScaling technologies.
It's a combination of service controlling and project deployment. It's not great, but it did do what I needed it for. I haven't touched the code since September when the system went live.
This project depends highly on custom changes within the Linux OS that you are running on EC2. As well as it's alpha quality, I'm putting it on Github for learning purposes mainly. Hopefully you'll find some parts of this project interesting.
SVN and no Git?!
The project Skyhook was initially intended for was using Subversion, despite my cries. As such, Git is not supported.
I am planning on cleanup, rewrite, add Git support, and many other things to Skyhook in the future when I have time. For now, dig through the code and config files if you're curious.
Please don't hesitate to fork and improve if you feel like it :)
To control multiple auto-scaled instances on EC2, I created Skyline.
