honest opinion?  smoke and mirrors.  i really have no idea.  i was
surprised to see the latency drop when we started using the VIP's we
assigned routing through our ec2 vyatta gateways.  it makes it nice
because it unties you from being 100% stuck on amazon.  you can design
your environment for cassandra with local nodes in an office if you
wanted ... it also solved the security problems i was coming across in
that before cassandra 0.8, intra-node communication IS NOT encrypted
or secured....

anyway .. the biggest thing for me was to ensure we are not tied to
one provider.  this was the best for my business case....also allowed
us to not be harmed by the!/search/amazonpocalypse ...
