Look at the BA (British Airways) disruptions and their analysis.
It will give you a concrete case linking the airline operation (operating aircrafts) with its faulty Cloud (reservation, billing, ticketing, check-in, supervision of flights, etc).
Cloud dependency has proven to be extreme. A 24 hour "no flight" breakdown seems to be traced to a human mistakenly unplugging the power supply to a blade memory (I heard this, but I have myself no proof that it happened exactly like this: end of disclaimer).
It remains a fact that Cloud dependencies are not always managed or even understood by users such as this company.
In another instance I have seen with my eyes the largest airport in Europe, London Heathrow, operate flight schedules with paper boards in the hall!
One could continue with Heathrow Express train displays either in Paddington Station or on the train, showing the recognisable blue faulty screen of Microsoft.
To remedy Cloud design faults, thorough risk and dependency analysis would be required.
An empiric way is to use the Edge more, to make it resilient and less dependent on the Cloud running fully. Another aspect never to underestimate is network connectivity and robustness to micro-disruptions in the protocol/packet structure.
Renaud Di Francesco thank you so much for your proposition ,you speak about Edge can you give me more information about this ,because i don 't have any idea about Edge
Edge Computing means not bringing all data and computations to the Cloud, physically in a data center behind massive network resources.
Edge Computations typically occurs when preprocessing or full processing occurs where the data has been acquired, sometimes in sensors. Imagine fire detectors (IoT sensors) in a storage room. Say you have ten of them, then a local algorithm does a first comparison and sends or not an alarm to the supervision center.
Edge Computing alleviates the load and burden of the network. It has been used by Mobile operators to reduce network load.
It is part of a Distributed Computing strategy, whereas the Cloud uses centralisation. For standards, look at ETSI MEC
