Amazon SimpleDB

Amazon added the final missing key ingredient to their online computing services Simple DB. Currently simple DB is in Limited Beta.

Thoughts based on initial read:
• Provides Web Service interface to Simple DB. Not traditional SQL.
• Provides Domains (Similar to Tables), Items (Similar to Rows) and Attributes (Similar to Columns).
• Provides Ability to create Domains, Get/Put/Delete items in Domains with attribute-value pairs for each item.
• Query can only be against a single Domain. (i.e Join’s are not possible).
• Currently Domain sizes are limited to 10GB.
• Similar to Google BigTable in design.
