These services are really really very useful in terms of developing and deploying web applications. Lots of issues like setting up new servers and configuring them, upgrading them will all together gets away in these cases...
Very useful i should say... It was all started by Amazon, bigtime web service provider as far as i know, with their S3 - Simple Storage Service.
Amazon S3 is intentionally built with a minimal feature set.
QUOTE
* Write, read, and delete objects containing from 1 byte to 5 gigabytes of data each. The number of objects you can store is unlimited.
* Each object is stored in a bucket and retrieved via a unique, developer-assigned key.
* A bucket can be located in the United States or in Europe. All objects within the bucket will be stored in the bucket's location, but the objects can be accessed from anywhere.
* Authentication mechanisms are provided to ensure that data is kept secure from unauthorized access. Objects can be made private or public, and rights can be granted to specific users.
* Uses standards-based REST and SOAP interfaces designed to work with any Internet-development toolkit.
* Built to be flexible so that protocol or functional layers can easily be added. Default download protocol is HTTP. A BitTorrent™ protocol interface is provided to lower costs for high-scale distribution. Additional interfaces will be added in the future.
Pricing
QUOTE
Pay only for what you use. There is no minimum fee. Estimate your monthly bill using the AWS Simple Monthly Calculator.
We charge less where our costs are less, thus some prices vary across geographic regions and are based on the location of the bucket.
United States
Storage
$0.15 per GB-Month of storage used
Data Transfer
$0.10 per GB - all data transfer in
$0.18 per GB - first 10 TB / month data transfer out
$0.16 per GB - next 40 TB / month data transfer out
$0.13 per GB - data transfer out / month over 50 TB
Requests
$0.01 per 1,000 PUT or LIST requests
$0.01 per 10,000 GET and all other requests*
* No charge for delete requests

Data transfer "in" and "out" refers to transfer into and out of Amazon S3. Data transferred between Amazon EC2 and Amazon S3, is free of charge (i.e., $0.00 per GB), except data transferred between Amazon EC2 and Amazon S3-Europe, which will be charged at regular rates.
Storage and bandwidth size includes all file overhead.
Great trends...
DaaS (Database as a Service) is becoming the next big thing in Data Storage where you just call API's for all your data needs and forget about DB servers, configs etc.

This technology is going to be the next step web.
