how does AWS S3 bucket Redundant storage works with filepicker/filestack

  • 772

I am using Filestack https://www.filestack.com/ as fileserver and Amazon S3 as filestorage as complete storage solution for my clients. Filestack offers CDN (Content Delivery Network) which serves file from nearest POP. Also i have chosen Redundant Storage for my bucket on Amazon S3. Now my question here is even though my images are stored at Amazon S3 and filestack, every-time a file is requested from filestack with its URL for ex, https://cdn.filepicker.io/api/file/h3C4wbHoTSaSltX354Ui why am i being charged at Amazon for Data Transfer I/O? I need to understand working between the two.

amazon-s3 file-server cdn

  1. To set the cache-control headers for a filepicker.io URL you can add the following parameter: cache=true and it will set the headers to Cache-Control: max-age=315360000

    For example: https://cdn.filepicker.io/api/file/h3C4wbHoTSaSltX354Ui?cache=true

  2. Did you set the "cache-control" header on your files in the S3 bucket?

    If not, the CDN will probably contact S3 on every request.

  3. I just had a glance on Filestack, but not sure how it works. I guess S3 would be talking to your filestack using API.? In that case Amazon S3 has bandwidth charges, especially when it goes to Internet from AWS data center.
