OTOH that is already here and carved in stone. Corporations have made that switch, so cloud dependency in general is already there from an architectural perspective. And of course you address availability and security via availability zones and redundancies and service policies etc. Corporations already have faced major cloud provider outages, which is why many have a so-called hybrid model, where they use some Hyperscaler capacity (AWS, Azure..) etc along with their own data centers but it's all managed with similar tools.IMHO even for corpos, there's a major catch - what if the cloud services (are brought to) fail, by hacking, sabotage, etc. ?
Their business will be "toast" in minutes.
We are not going back to traditional Client-Server architectures anytime soon.
