Today’s world is very different from what it was 20 years ago. We are used to a website loading in a second, a mobile app calculating a complex route in moments, or ordering a taxi with one button. This is made possible by combining many technologies and approaches that ensure smooth and fast operation.

It is hard to imagine a taxi service suddenly stopping for 10 minutes. It is equally hard to picture a map or GPS navigator that suddenly stops updating, or a major online store freezing during payment.
