> For those that do need to use cloud, just make sure you are running your services in different failure zones.

By which time you might as well just roll out your own kit in colocation or your own datacentres.

The cloud providers are nickle and dimers, they charge you for every little tiny thing.

Cloud might look cheap at cents-per-hour, but then you find you need X "services" to deliver your Service and so you are talking about exponential cents-per-hour (X cloud services times x cents-per-hour).

And then running your services across failure zones will of course cost you more beyond the basic double-cost, because most cloud providers charge by the GB for cross-zone traffic. So if you're doing cross-zone replication, that's gonna cost you a pretty penny.

Meanwhile, in your own colo/DC, you have predictable costs. And you can get redundant connections between sites for a flat rate, not some stupid per GB fee.
