In this post, I will discuss if there is a difference between resilience and fault tolerance when talking about IT systems.

Resilience IMO is a huge topic. It has a broader scope than most people think and – even more important – it has become much more relevant for most of us than most people imagine. Thus, time to shed some light on this topic. Over the course of several posts in the future I will discuss several aspects of resilience. Of course, my main focus will still be IT. But in some places I will leave the boundaries of IT as this topic affects – and supports – us in many ways.

This blog post is about an observation I made pondering the slow adoption rates of several technologies in IT that I consider being game changers. My claim is:

Probably you also heard it several times before. Someone comes along saying that IT is a young and immature domain. That we are not yet an engineering discipline. That the way we write code sucks: Slow, not enough throughput, error-prone, not easily repeatable.

The speed of the IT value chain often is a topic in discussions I have with decision makers. The common theme is: The IT value chain is too slow. We need to deliver faster.
