What's the line from Contact?

why build one when you can have two at twice the price?

But, if you're building a datacenter for $5M, spending $10-15M for redundant datacenters (even with extra networking costs), would still be cheaper than their estimated $25M cloud costs.

Or build two 2.5MM DCs (if can parallelize your workload well enough) and in case of disaster, you only lose capacity.

You need however plan for 1MM+ pa in OPEX because good SREs ain’t cheap (or hardware guys building and maintaining machines)
