Number of Buckets in Amazon Free Tier

I am trying out Amazon S3 for my file uploads and would like to store different buckets for development, test and pr开发者_如何转开发oduction environments. In amazon documentation it was mentioned the following statement

As part of the AWS Free Usage Tier, you can get started with Amazon S3 for free. Upon sign-up, new AWS customers receive 5 GB of Amazon S3 storage, 20,000 Get Requests, 2,000 Put Requests, 15GB of data transfer in, and 15GB of data transfer out each month for one year.

Is there any limitation about the number of buckets. I mean if I have three buckets and If I use within the overall storage limit, will I be charged.

Each account in AWS is limited to 100 buckets -- even if you are paying the normal usage rates.

Buckets are not billable items in S3.

If the limit of 100 is not enough you can create virtual folders in your buckets and structure your environment that way.
