Convergence, Immutability, and Image-based Deployments

As our industry continues to adopt lean methodologies in an effort to improve the workflow of product deliverables, it’s important that the products developed using these patterns are reliable. When speaking from an application infrastructure perspective, or the Ops side of DevOps, this means that we must continue to improve resiliency, predictability, and consistency, alongside streamlining our development workflows to allow for failing fast, and failing often.When faced with a critical incident, it’s dissatisfying to find that the root cause was an environment delta that only affected a subset of your infrastructure.  You begin asking questions like, “Why aren’t all our nodes configured with the same parameters?
