Hi Folks, I figure somebody here might have already done this exercise (maybe even have a spreadsheet :-).
I'm working on an application that might be thought of a hybrid cloud version of Amazon S3 - and I'm trying to do some back-of-the-envelope cost estimating. Amazon prices S3 at $.03/gig/mo. - which, I assume, includes their costs of redundancy - and I'm wondering what goes into that price. Baseline scenario: - 1 PetaByte mirrored at 3 data centers - we purchase the hardware, and put it in racks at commercial data centers Obvious cost elements: - disk drives - servers - rack space - power - network connectivity - sys admin time - <what am I missing?> I'm trying to get to some rough numbers for: - initial capital cost - annual maintenance cost (service contracts, periodic hardware replacement) - annual data center costs (including network) - incremental costs of adding storage - how things change if we started with a baseline of 100TB (where do the economies of scale start kicking in?) So far, the main datapoint I have is: - Backblaze publishes details of the "storage pods" for their backup service. The latest version (https://www.backblaze.com/blog/open-source-data-storage-server/) seems to come in at "4U server with 480TB of data storage for less than a nickel ($0.05) a gigabyte" Can anybody provide any other benchmarks and/or some guidance as to how to build up a full cost model? Thanks very much, Miles Fidelman -- In theory, there is no difference between theory and practice. In practice, there is. ....
