Re: Generation of traffic in "settled" peering arrangement

[Jason Zigmont <jzigmont () globalcenter net>]

Here's the issue.  Customers like the idea of distributed architecture, but
are reluctant to do it.   We've (FGC) developed an intelligent DNS product
that works like a Cisco Distributed director, and can offer it for free to
our customers.   It does not cost customers anything additional to be in
two sites, but they do not want the management hassles.  

One of the main issues for large sites is database replication.   For
example.  If you have a search engine in both Herndon VA, and Sunnyvale,
CA, the amount of cross country bandwidth to reliably do database
replication in real time is huge.  Therefore it is easier for that site to
stay in one location.    If you have a static site with no database,
chances are they are not large enough to need a distributed architecture.
