We are extremely satisfied with EC2/S3 for our startup. The service has saved us a great deal of time we would otherwise have had to spend on the hardware side.

The great thing about the success of EC2/S3 is there are a large number of competitors coming out with similar services.

Should help to push prices down, I would stick with zon's because they have been so reliable.

At first it seemed like S3/EC2 was a way for Amazon to use their spare capacity and CPU cycles by renting overhead out. But now, that supposed sliver is a slice > 50%? That's impressive.

wow this is very surprising and impressive.

Does anyone have a list of the biggest AWS users?

Now, if they would just bring SimpleDB out of closed beta so others can use it...

What's interesting is that this happened during the holiday shopping season in the 4th Quarter, which is Amazon's busiest time for its own Web sites.

Probably also the busiest time for their clients too.

Long live S3.
