Mounting Amazon S3 bucket for use in web application

I will be launching a web application soon which will require users to upload pictures for others to view. I would like to use Amazon S3 to store the images as it scales and is cheap. The user will use a form to upload their file, it will be processed with php and saved to the S3 mount thats attached to the web server.

I am anticipating and开发者_如何转开发 hoping tens or hundreds of thousands of images will eventually be uploaded.

My first question is whether an S3 bucket mount is robust and fast enough for such an application, or would I be better off using Amazon EBS. Although I'd like to have my own dedicated box rather than use an EC2 instance.

Also, I am at this point unfamiliar with S3, but when I do upload files, is it appropriate to put them in a single bucket rather than a cascade of directories? It seems it might be ok since each 'bucket' is virtual anyway.

One of the things you can do is to have your users upload to S3 bucket directly, unless you want to do some processing. You can use POST to upload the files to S3 or one of the 3rd party components such as http://flajaxian.com/ This way you can significantly offload your server.

As for your second question it is actually up to you how your design your app. there is no pros and cons.
