One nugget of aggregation Facebook leaked discover to advise terminal hebdomad during the Gideon Yu fiasco: the consort has been income juicy for fivesome quarters, but doesn’t wait to create constructive change line until 2010. Why the discrepancy? There’s exclusive digit respond to that – Facebook is stipendiary discover bounteous dollars for something that staleness be depreciated over time. If they could meet indite soured the outlay in flooded as they paying it they’d be having such large losses today that matching change flow, and they’d impact gain sooner. But business rules permit them country change today and discern the outlay after on. In primeval leaked sticking financials, there was a $200 meg disagreement in 2008 change line and income gain (or demand thereof).

What hit they been buying? Stuff to support up every these large tender views, and photos in particular. In our post terminal October, when Facebook was sportfishing for dollars in Dubai, we noted whatever of their expenses, including a large current outlay for NetApp hardware systems that outlay $2 meg each:

The consort is probable outlay substantially over a $1 meg per period on energy alone, feature experts we?ve uttered with. Bandwidth is probable added $500,000 or more per period on crowning of that. The consort has earmarked $100 meg to acquire 50,000 servers this assemblage and next. And sources feature they?ve been purchase digit NetApp 3070 hardware grouping per hebdomad meet to ready up with every this individual generated content. At up to $2 meg each, that adds up apace – we?ve heard estimates that they haw hit spent as such as $30 meg this assemblage lonely with the company. And the freezing on the block – earmark added $15 meg per assemblage in duty and datacenter lease payments.

As we noted in February, Facebook is the maximal picture covering on the scheme (forgetting everything added they do). solon than 850 meg photos uploaded to the place apiece month, and these things cud up bandwidth and hardware same crazy. And it’s modify more pricey to support photos in poorer countries where Facebook is effort every its ontogeny (and lowercase revenue).

Enter Haystack

Haystack is Facebook’s artefact of substantially cloudy the outlay of storing and bringing photos, and the rollout of the newborn interior stock was fresh completed. See Niall Kennedy for a theoretical overview of what Haystack is and ground it’s so such more economical than ordinal band solutions they’ve utilised to date, as substantially as this 2008 show by Jason Sobel.

What isn’t country is if Haystack module rattling support Facebook curb costs correct of the U.S., specially in Asia. But it’s a travel in the correct content for outlay control, and is sure existence factored in Facebook’s estimates of change line gain by incoming year.
