AWS virtual storage revenues seem a bit cloudy?
The post states that AWS storage revenues are $2B, is that in USD or Euro?
Note that Amazon reports Product, Services and Others, where a common mistake might be to conclude that AWS is services, however keep in mind that Amazon has services such as Prime for video, audio, not to mention Kindle and Amazon Studios that are not AWS.
Amazon states as of Q113 (e.g. back in April) that their "Other" earnings had a Trailing Twelve Month (TTM) earning of about $2.820B (USD) which includes other non product sales such as marketing, promo, other seller sites, credit cards and AWS.
Thus a reasonable estimate would be that AWS accounts for around 70-75% of "Other Revenue" so at 75% TTM that would be about $2.115B (USD) in revenue, however also keep in mind the following. EC2 is estimated to be in excess of 60% of AWS Revenues, with Storage (e.g. S3 (Standard + RR + Glacier) + EBS + RDS) making up around 21% with the balance being other services (ELB, CDN, etc...) plus fees (API, IO, Bandwdith, Event notifications via CloudWatch etc among others). Thus some rough math shows that AWS storage is more like $0.444B, however for fun, lets also keep in mind that some of the "Other AWS" bucket includes some storage, as well as EC2 images can have storage (regular HDD or SSD) with high storage space and high IO instances, similar to DAS in a regular server you could buy. Since we are all just speculating and throwing numbers out here or perhaps using some Piroma calculations/estimates/modeling techniques, lets say AWS storage using the above (e.g. estimated storage + plus some of the storage from EC2 and RDS not to mention a portion of the other fees is around $0.899B (USD) which IMHO is on the agressive side.
So where is the other $1.1B (USD) in estimated AWS storage revenue coming from that is mentioned in the above post as non of the financial analyst seem to have that insight nor anything found in the Amazon SEC filings? Otoh, perhaps there is something being lost in currency translation from dollars to Euros, however that too would be an ugly exchange rate.
Now on the other hand, lets pretend and speculate for a minute that by chance AWS is actually at a TTM storage revenue rate of $2B USD, that does not reflect how much space capacity is being deployed and if AWS is actually using storage as a loss leader for other things.
Likewise if that speculated $2B USD storage revenue were real today, keep in mind that would also include comparable database software sales and some server, thus not just apples to apples of comparison between a storage vendor storage sales to AWS. A more comparable or target market comparison then would be AWS vs. Storage Vendors + Database software vendors + plus some others.
Does this mean AWS is not a force to be taken lightly? AWS is growing and is the giant with others in the market (e.g. Rackspace growth their offerings from hosting to include more cloud, Azure, Joyent, HP, Centurylink/Savvis and many others)...
