I am specifically saying that redundancy doesn’t solve everything magically. Redundancy means coordination, more things that can also fail. A redundant system needs more care, more maintenance, more skills, more cost. If a company decides to use something more sophisticated without the corresponding effort, it’s making things worse. If a company with a 10 people department thinks that using Cloud it can have a resilient system like it could with 40 people building it, they are wrong, because they now have a system way more complex that they can handle, despite the fact that storage is replicated easily by clicking in the GUI.
