No, history showed DNS round robin proved abysmal, it led to real load
balancing hardware and software being born.
These changes don't affect us, we've never used director, hardware load
balancers FTW, and no replicator, nightly snapshots and multiple levels
of raid on a NAS backend, but I do see smaller installs where it may be
preferable to buying a $200k NAS :)
However, for those with shoe string budgets, for load balancing, this
can be overcome by a software version, there are some for no cost if you
have a spare machine, you might even pick up a real cheap old hardware
balancer on likes of ebay.
but it more of a last line failover, and during the time it takes for
DNS to retry, and find another active node, an AWFUL lot of disgruntled
customers will be calling ;)
Ahhh reminds me on the very early 90's :)
