It's the boring solution. It should also only be the default answer if you are not building a super critical system to life and limb. But it certainly gives a much lower total cost of ownership. If you don't have the resources for some big redundant system, I've too often seen the complexity added by the redundant system be the issue then focusing on simplicity. If you need to add a bunch of people to support complexity but both the money and the risk assessment doesn't call for it, simpler is much better. I won't say I haven't seen the issue where eventually it was only a huge project to go forward, but I tend to think sometimes even that is less then the sum of having dealt with complexity to that point, it's dependent on a lot about what you are building.
