We've been using Salt in Ops for almost two years now. It's reduced our new server deployment times from weeks to under 10 minutes, and we now can guarantee that every server is exactly the same. It's been absolutely game-changing for us. As the Network Engineer, I didn't have much to do with Salt during that time. That has been changing as I've been trying to apply DevOps principles into the network side of things (it's a brave new world!). Being two years behind, I needed to get up to speed quickly on Salt. This book was the perfect overview/primer on Salt for someone who didn't know a highstate from a topfile. It will walk you step-by-step through the deployment of your first salt master and your first few minions. It will give you examples and overviews of the largest features of Salt, including modules, states, topfiles, environments, Salt-cloud, maps, events, and reactors. It's not a long read, and you shouldn't expect too much depth out of the material, but it is perfect in what it is: a well-written and thought-out primer. I spent the weekend going through the book and examples with a couple of VMs and I now feel confident talking with our Ops team about Salt. I feel confident enough to start writing my own modules and reactors. I also feel confident in my ability to learn more and figure things out on my own through the Salt documentation that the text shows you how to use. If you're brand new to Salt, and you need to get up to speed quickly, this is definitely the way to go.
