consumes huge amount of bandwidth as its main business is streaming. This
posts more requirements on the construction of datacenter, location(related

making the bet on AWS.
Other companies, let's say even twitter, might be more flexible on this.

发帖数: 8232 | 28 storage is cheap, only 7c per GB per month on S 3. they charge more by
network usage .
One example is that a new device is coming online , Nflx needs to encode
millions of movies to support that, it would be easy to get a couple of
hundreds machines from aws to run that job for a short period of time. It
takes weeks of you are on your own dc. aws is great for those kind of tasks
Anyway, Nflx is a bit extream. Everything is on aws .

发帖数: 1453 | 30 If very few people look at that, 7c per GB sitting on disk might be still
considered a waste. Once you start to use cloud storage, very soon you will
end up with finding a solution to clean up. Actually I don't think any
company afford to put all movies/tv online. I just feel Netflix has a tight
budget on this as some movies are swapped out so fast.

发帖数: 34805 | 31 Netflix owns its own CDN called Open connect, which includes special
hardware and its own open source software server. While encoding is done on
AWS, CDN is not.
In Netflix term, content licensing is expensive, which is the majority of
budget. Everything else, including staffing cost is not. Hosting cost is
marginal as far as I know. I believe the management want to keep the
flexibility of not having to operate data centers.

发帖数: 6934 | 35 this is why i said maybe they need their cloud to be super elastic, so you
can quickly spin up a whole bunch machines and quickly decommission them.
another reason may be as the other poster said, they did it at the beginning
when scale wasn't huge. But with the current scale switching cost (time and
resource) is too high.
