Is the price less for this? It doesn't say.

Is the price less for this? It doesn't say.
- amock 16y agohttps://aws.amazon.com/s3/#pricing https://aws.amazon.com/s3/#pricing gives the new pricing.
- justinsb 16y agoPricing starts at 10c/GB rather than 15c/GB; hence I figured it's stored in 2 locations rather than S3's default 3 location redundancy.
- tlrobinson 16y agoDoes that match up with the 99.999999999% vs 99.99% durability figures? I don't know what the proper math is here. edit: they do explicitly say "Designed to sustain the concurrent loss of data in two facilities"
- justinsb 16y agoI think you're right ... I don't see how these figures are consistent. Maybe they're factoring in the time it takes to restore a copy, maybe 'normal redundancy' S3 is doing something clever, maybe it's simply another instance of Amazon being economical with the truth.
- gduffy 16y agoInexact at best, but .. P(3 locations failing) = 1-0.99999999999 P(1 location failing) = P(3 locations failing)^(1/3) = 0.000215443475 P(2 locations failing) = P(1 location failing)^2 = 0.999569159
- dfranke 16y agoThere is no proper math. 99.999999999% is a very silly number. The probability of all of Amazon's datacenters being destroyed in nuclear war within the next year well exceeds 0.000000001%.
