linux autoscaler with F/OSS

Question

I'd like to implement an autoscaler using Linux, something with the functionality of the AWS autoscaler -- that is, I'm not running in AWS but I'd like to have a similar device :)

Has anyone done something like this? Any ideas of where to start with open-source tools?

Answer 1

You might consider something like Apache Mesos or some of its competitors/peers. It probably does more than what you want, but may fit the bill. I guess part of the question is if you are scaling at the application level or the os level. The Apache Mesos project is here: https://mesos.apache.org/

Edit... Hashicorp focuses a lot on work in the virtualization area and have open source tooling ( https://www.hashicorp.com/#open-source-tools ). Likewise, you could look at Docker and similar Container technologies. They are lower level and lighter-weight than virtual machines. The tooling comes in commercial and open source varieties.
