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.

Change is hard.

In the previous post we discussed the evolution of the public cloud offerings from their beginnings until around 2015, starting at the plain compute and storage level and working their way up to the PaaS level.

Discussing with other people, I often realize that many of them have not yet understood how much of a revolution public cloud is. In my previous posts, I already discussed why I think cloud-ready is not a viable strategy and the disruption delay which also affects cloud computing. Here I would like to add a different perspective.
