If I had my hand full of truth, I would take good care how I opened it


Back story… tl;dr - some monitoring back story and not being dogmatic about your beliefs. UPDATE: I am writing a book about Prometheus take a look. As many folks know, I am one of the maintainers of Riemann, an event stream processor focussed on monitoring distributed systems. I wrote a book about monitoring in which I used Riemann as a centerpiece to explore new monitoring patterns and approaches. In the book, I describe an architecture of whitebox monitoring (with some selective blackbox monitoring) using a push-based model.

The Packer Book

Announcing The Packer Book I’m announcing my new book: The Packer Book. I’ve been using Packer for a couple of years now. It’s the best image builder currently available and dovetails neatly with configuration management tools and other Hashicorp tools like Terraform. The book is a hands-on crash course.

We also delve into extending Packer with plug-ins and writing your own plug-ins.

The Terraform Book

Announcing The Terraform Book I’d like to announce my next book: The Terraform Book. I’ve been excited about Terraform for a while now. Like many emerging technologies the materials, beyond the documentation, are a mish-mash of dated blog posts and Gists. To help folks getting started with Terraform I decided to write an introductory book. The book is a hands-on crash course. We cover installing Terraform and building simple infrastructure. We build upon this with more complex features and advanced examples including:
