Infrastructures have long been taken for granted. They are part of our lives and we do not even notice that they are there until they malfunction or fail. In a sense, an infrastructure and its services perform at their best when they go almost unnoticed. We rely on our energy supply without really thinking about it, we expect that when we open our tap, that we will get water. And the omnipresence of IT and its infrastructures in the form of smart phones, tablets and laptops is just regular part of our daily lives. Maybe only the transportation infrastructures make us aware on a regular basis that infrastructure systems and services could actually fail or underperform.
