Ubuntu Update Process for Multiple Servers

Hi All,

We are looking at the best way to keep our Ubuntu servers up to date over time - as in OS updates and package updates.

Obviously, we can log into the servers and run “apt-get update”, etc. manually, but when you have more than a few it just becomes impractical. We’re trying to minimise the time and admin involved in this process and get us back to coding!

I am wondering what other people are doing out there?
We have looked at something like apt-dater http://www.ibh.de/apt-dater/ which looks very promising.
Another option is just automating with a cronjob, however I don’t think it’s something that can be completely automated as it is good to see what updates are going through and sometimes hold off on things.

Would love to know how people are handling this at the moment.

Thanks.
