使用Amazon S3进行图像存储。 我应该在哪里存储我的元数据？

Question

Background: I am new to cloud computing and large scale DB design. I have to find a storage facility for a large number of images that have a lot of metadata associated with each image. I am going to use Amazon S3 to store my image files and I need a cloud based database solution to store metadata and reference to each image. I need this so I can query a DB for customer request and pull images and their metadata and insert new data as well via some web and mobile application interface I will create.

Research done: I found the S3 is a raw data storage solution. I found many good discussions here on bucket naming conventions and I see many people use S3 as binary storage and use a DB for metadata. I've done some research on mongoDB, dynamoDB, and other database solutions.

Question: I need a direction of where I can find an inexpensive and reliable Database that will work well with Amazon S3, that is ideal for large amount of metadata storage.

Well if you are not looking for a relational DB, why not try http://aws.amazon.com/simpledb/

and if you want RDMS how about http://aws.amazon.com/rds/
