Research purposes. I wished to get a better understanding from experts with experience in cloud adoption of what may hinder some businesses from moving to the cloud.
Cloud issues are not just security issues.
Here is another one: network and system "always on" and running. Just in air transport I have two examples of recurring problems due to inappropriate use of the Cloud (without enough reliability and backup):
-Heathrow Airport (London)
The flight information system is displayed on large screens and passengers go to gate as displayed. If gates are not displayed then passengers do not know where to go, and chaos appears, leading to major flight disruptions from Heathrow Airport.
I have seen a repeat of the same problem: disruption of the IT system (Cloud) allocating the flights to gates, and sending the information to large displays. In that case Heathrow airport switched back to Paper Boards, and flights and gates are handwritten by staff. Beautiful Cloud! Cloudy day... Messy day.
-British Airways
British Airways operation is Cloud based. There has been a 1 day (24 hours) disruption of all flights of British Airways due to a faulty Cloud. Everything is connected, ok, but what if just one piece gets disconnected (like a blade memory, a HDD) and worse, gets reconnected without the system being aware of what has happened, and because of imperfect software design, part A waits for part B which waits for part C which waits for part A... Then it does not start again, until the vicious circle is broken. I am not sure of the details of what happened at British Airways, but I am sure of the result: a simple IT fault in just one place resulted in a faulty operation and zero flight for 24 hours. Lots of money lost.
Cloud is not just a security concern, it can be a reliability concern: Cloud is great if network and IT systems are always on, or if there is a back-up when one piece is not working.
That is why Edge Computing is an interesting approach: do locally what you can do locally, and do not assume the network (or another IT resource) is available, it may not be.
It's called Robust Cloud Design...
Does this help you?
Yes. These are very valid issues! Thank you! I will follow up on this also.
