I simply do not see how competing cloud vendors can keep up with this. Most of them are still struggling to provide anything beyond a simple API to start/stop machines.

#12"Amazon DynamoDB stores data on Solid State Drives (SSDs)" This is big.
I'd imagine we'll soon see a SSD option for EBS volumes. Sounds like it'll be pricier (as you'd expect) - $1/GB for DynamoDB storage (but replicated to three volumes, sounds like).

#13From the limits page(1) I see you can only have 256 tables per account. (1) http://docs.amazonwebservices.com/amazondynamodb/latest/deve...
As with all the other AWS services you can have your limits lifted upon request.
Does that apply for the 50-per-account cap on S3 buckets as well?

#14Here's a brief overview comparison of DynamoDB vs. BigTable: http://vschart.com/compare/dynamo-db/vs/bigtable The site is also able to compare many other different databases.
It seems as if this site is a user-edited wiki, and there are a lot of things that need to be filled in (in case anybody is up to speed on DynamoDB and wants to help). For instance, the Map/Reduce entry was still '?' when I wrote this.

#15For about $15/month for minimal "reserved capacity" charges and $1/gigabyte per month replicated disk space this service looks like it will cure a lot of deployment headaches for a reasonable cost.
Interesting that when I signed up for the service that they verified my identity with a cellphone call, like Google sometimes does.

#16What's the concern for lock-in here - how difficult with DynamoDB be to migrate away from? Amazon seems to be increasingly catching the App Engine Syndrome, though to be fair, it's been mostly network traffic-style functionality in the past.

#17There are some bugs in signing up for the service. In console, if I go to dynamoDB tab I am asked to Sign Up first. I click the sign up button and I am told "You already have access to Amazon DynamoDB". Repeat.

#18I would love the option to add N index (at cost).
My guess is they will add options for additional indexes in the future...everyone needs start somewhere. Even at Amazon's size and scale.

#19Why is there a 1MB reply limit on BatchGets and obviously no limit on Gets?
Did anybody find limits on a single item?

Well, Azure has been offering a similar NoSQL service for a few years now.
