What's the line from Contact?
replywhy 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.
replyYou need however plan for 1MM+ pa in OPEX because good SREs ain’t cheap (or hardware guys building and maintaining machines)
