Author Interview with Diego Zamboni

What made you write the book?

CFEngine 3 is a powerful tool with ample reference documentation, but I realized that it was lacking in good 'getting started' documents. This is the gap that I intended to fill with this book‚ to guide CFEngine beginners from zero to being proficient in using CFEngine for system maintenance, and to prepare them to further explore the more advanced resources on their own.


Why is your book especially important now?

Infrastructure has grown more and more complex in recent years, yet users expect agility, flexibility, and customizability in how systems behave. CFEngine allows system administrators to stay on top of that game by expressing the desired state of the systems, leaving the low-level details for CFEngine to manage automatically, and making use of the knowledge that CFEngine can provide about the state of the infrastructure. This book makes it easier for sysadmins (both novice and experienced) to get started with CFEngine quickly, and to take advantage of its many powerful features as soon as possible.


What is the single most important thing readers will be able to do after reading your book?

They will be able to set up CFEngine on a network of systems, and use it to manage all the basic system administration tasks needed to keep them running.


What do you think is on the horizon for your readers?

Learning CFEngine is vitally important because infrastructure complexity will only keep growing, and we are well past the point when a sysadmin was able to comprehend the whole infrastructure. Today's infrastructure is dynamic, personalized, and malleable. Users expect changes to take effect immediately, and to be able to affect much of those changes themselves. The next generation of system administrator needs to be an 'Infrastructure Engineer.' He needs to deploy, configure, and maintain complex applications and services across a breadth of servers, clients, clouds, networked devices, tablets, smart-phones, and toasters. She needs tools that empower her to acquire and express knowledge about systems in a scalable, comprehensive and agile way. CFEngine provides this ability.

I already wrote a long review of this book, if you want to read it google for "cmdln learning cfengine3 review"

The short version is: Buy it!

I can't rec­om­mend this book enough. If your just learn­ing CFEngine 3, if you are versed but not an expert and you like CFEngine you will like this book. If you meet all those cri­te­ria and you don't like the book, I'll buy you a beer if we ever meet.

...

Well, that's it. So basi­cally I had 3 wants after read­ing this book, and all cen­tered around more infor­ma­tion. I say that's pretty good. After all you cant please every­one, and I have been known to be highly crit­i­cal. It really is one of the best tech­ni­cal books I have read in a while. I didn't find it a dry read at all.

I bought another book about CFEngine a few weeks ago, and at half of it, I was not able to understand anything about CFEngine yet. The philosophy around promises, presented and explained by Mark Burgess videos wasn't there, and I almost gave up on CFEngine. It was just bad examples, dumb recipes, going against what the author of CFEngine wanted.

Then I bought this book, and I saw the light! I've now read the book and I'm writing clean CFEngine recipes with the feeling of doing a good job, which won't block me in the future.

This *is* the book about CFEngine 3.
Start with this one if you want to commit to the real CFEngine philosophy, the productive and clean one.

The best book on CFEngine3 I've found (not that there's a whole lot of competition in that particular space). Plenty of guidance and worth owning if you have to do any work with CFEngine3.
