But Cloud is better than In House!
Yes, loads of companies do in house stuff badly or don't bother with resilience or disaster planing etc. So the argument is that the Cloud is better.
Maybe from the point of view of the users in one company cloud is better than In house, perhaps you can't then order from one supplier when their in house IT falls over if they don't use cloud.
But the "cloud" could mean that no-one can order from anyone. Instead of just RBS or HSBC being down all banks, Mobile billing (so no mobile calls due to no credit, PAYG or Bill Pay), no ATMS, no POS, no card payments ...
Maybe fantasy today, but not as more companies outsource to cloud EVEN if it's done better than in house. Not as we head toward various mono cultures. It won't be a cyber war, but a Friday afternoon patch to Edge Routers, or load balancing, or DNS servers, or database etc.
The famines in the 19th Century (not just in Ireland) were due to mono culture.
The very concept and "savings involved" of Cloud Computing is heading all of the first World to a cyber potato event horizon.
