While I still haven’t had time to play around with Amazon’s S3 and EC2, they’ve added yet another offering with SimpleDB.

This offering removes one more barrier to scaling software. Dave Winer comments that Amazon is becoming the place for developers to work with in order to scale their products.

I’ve thought about using the systems for record indexing and some of the more intensive processes that libraries wouldn’t necessarily have the hardware investment for.

Inside looking out has a nice short breakdown including that it may be written in erlang. Marcelo looked at the API and thinks it’s really a directory service and that search might be the killer use:

There’s also a breakdown on prices and comparison with the other services on O’reilly radar.

I’ve seen various projects for using S3 as the storage backend for databases like mysql. It will be interesting to see what projects come out for SimpleDB.
