I bet those that use(d) Amazon Cloud Services agree. How many times has it gone down now? I've lost count.
Didn't Amazon say that happened to those who chose to only host their product in a single Amazon Cloud data center?
Making it so that it's hosted in multiple Amazon Cloud data centers (East Coast, Central, and West Coast) makes for a completely redundant system. If one data center fails, you have the other two.
It might make for a redundant cloud-site end point, but it hardly makes for a "completely redundant system".
Most companies, at a given facility site, have one computer network to which all their PC's, terminals, and workstations are tied. That network is controlled from within a single server/interface center, powered from one service connection to one power grid, and that's connected to one physical data pipeline (copper, fiber, microwave) that routes traffic to one Internet provider who operates through one primary Internet backbone service. Does anyone else sense anything "vulnerable" about such a lengthy chain, whether or not it's connected to a "redundant cloud-site"?
Over the years, system design-for-reliability has involved constantly striving to identify and eliminate single-point failures, or at least to minimize the consequences flowing from such failures as might occur. Yet a primary thrust of modern computerization (or at least the last 20 years of it) seems bent on creating as many single-point failure sites as possible, while maximizing the possible negative consequences flowing from a failure at any one of them.
Perhaps some companies will indeed use redundant cloud data centers. And perhaps some companies will deal with the many other single-point vulnerabilities in their data systems. But most won't do either. And that's
where the rubber will meet the road at some ugly point during some ugly crisis on down the way.--
