Re: Seems that generators are a bit of danger
"I sometimes wonder whether cloud-only is even worth it for anything bigger than SME."
This is not a good example to make that point. The location here is a lot more like what local servers are like than what cloud is like. The large cloud providers operate so many datacenters that they can afford to do lots of expensive things that local or colocated servers don't do for the expense. DR is often one of those things. Large cloud providers also have built-in features for redundancy across datacenters or regions. Meanwhile, a lot of companies will either colocate their servers in a datacenter not unlike the one in this article or will run a facility of their own which isn't much different. This obviously doesn't apply to companies which spend a lot of time and effort on their servers, including really big places or ones with a lot of technical knowledge available, but it does for many others.
Cloud has a lot of downsides. You pay for lots of things you don't have to when running locally, the prices may be higher which you can only figure out by spending time on a boring effort to calculate them, you have another supplier on which you're relying, all that. However, if you're concerned about disasters, it is a lot cheaper to run redundant systems on cloud than to run them yourself unless you have a lot of servers. Now that's not necessarily a reason to go all cloud. You could run redundant systems in colocation datacenters or even run some locally with cloud backup. For a lot of businesses who don't bother with geographic redundancy at the moment, the extra cost of multiple servers to perform one task may not be judged worth it.
