At first sight, you may wonder what is the best automation tool that will be useful for our OpenStack "production day". We have already chosen Git and Jenkins to handle our continuous and delivery code infrastructure. It is time to choose the right tool for automation.

Eventually, it might be difficult to select the right tool. Most likely, you'll have to choose between several of them. Covering all the existing IT automation tools could fill an entire book or even books. Therefore, giving succinct hints on different tools might be helpful in order to distinguish the best outfit for certain particular setups. Of course, we are still talking about large infrastructures with heterogeneous systems, a lot of networking, and distributed services.

Giving the chance for one or more tools to be selected as system management parties can be effective and fast for our deployment. We will use Chef for the next deployment phase.
