White noise is a common synthetic noise source used for sound masking by a Tinnitus masker.

White noise machines are sold as privacy enhancers and sleep aids and to mask tinnitus. White noise CDs, when used with headphones, can aid concentration by blocking out irritating or distracting noises in a person's environment. In open plan offices, large corporations such as ExxonMobil apply white noise to reduce the reach of speech, thus, by preventing office staff from being distracted by conversations in the background, safeguarding productivity.

Please correct me if I am wrong but doesn't using a global sequence mean all the threads wanting to insert a record have to queue up and wait for the db to provide the auto increment id? I am not sure what time this takes but may be it creates a bottleneck for really large, write heavy applications.

Create a free RightScale account and check out their shell scripts. One can get good ideas of automation from them.

I've used EC2 for running web servers as well as database server with the db servers being replicated to rackspace for backup.

I have always wondered about how EBS as disk will affect database as it is essentially a network drive. Any info on that would be great.
