I recall that I saw financial statement of WMF that states around
$2.3M
was spent for Internet Hosting. I am not sure whether it includes
management cost for computing resources
(server clusters such as eqiad) or not.
That's the cost for datacenters, hardware, bandwidth, etc..
Not sure following simple calculation works;
117 TB per day, for 365 days, if $0.05 per GB, then it is around
$2.2M.
Maybe it would be more accurate if I contact analytics team
directly.
That calculation doesn't work because it doesn't take into account
peering
agreements, or donated (or heavily discounted) transit contracts.
Bandwidth
is one of the cheaper overall costs.
Something your design doesn't take into account for bandwidth costs
is that
the world is trending to mobile and mobile bandwidth costs are
generally
very high. It's likely this p2p approach will be many orders of
magnitude
more expensive than the current approach.
A decentralized approach doesn't benefit from the economics of scale.
Instead of being able to negotiate transit pricing and eliminating
cost
through peering, you're externalizing the cost at the consumer rate,
which
is the highest possible rate.
While that is often true, there are notable exception, growing both in
scale
and number.
a) We have campus situations where a large university, company, or
public
agency with tens or hundreds of thousands of peers run a network that
they
pay for anyways, that is needed for peers to connect to Wiki* anyways,
and
that is available to peers at no (additional) cost. While external
traffic cost
are of relatively little concern, quick response times often are,
especially
in classroom situations where up to several hundred students may look
at
the same articles virtually at once.
If we wanted to address such a situation, it sounds like it would be
less complex to just setup a varnish box (With access to the HTCP
cache clear packets), on that campus.
