Which data transfer is free in Amazon S3?
SHORT ANSWER
Four kinds of trip cost $0: files coming in, the first 100 GB a month going out, files moving between Amazon services in the same region, and files handed to the delivery network.
The lesson 3 film is on chapter 1.
The free trips
- In. Uploading is free, however much you upload.
- The first 100 GB out each month, about 25,000 photos, counted across your whole account.
- Inside Amazon. From S3 to a server you rent from Amazon in the same region, free.
- To CloudFront, the Amazon delivery network, free. CloudFront then charges its own lower rates with a bigger free allowance, which is why it sits in front of files served to the public.
The trips that cost
- $0.09per GB
- out to the internet past the free 100 GB, so $83 for a terabyte
- $0.02per GB
- to another Amazon region, so $20 for a terabyte
- $0.085per GB
- out through CloudFront instead, after its 1 TB a month free
