How do different AWS regions compare to one another? A benchmark of transferring data from EC2 instances to S3 buckets
Many developers choose to host their data and code in the Amazon Web Services cloud, but when it comes to choosing a region it’s not that clear how to choose between the different options. To help shed some light on this, we’ve tested the upload/download speeds between the 8 available AWS regions – in the US, Asia, South America, Europe and Australia. We wanted to learn about the tradeoffs between regions and what kind of speeds to expect.
To add more insight, we then compared the results to a similar test we ran last year, which helped shed some light into the changes Amazon has made since. An interesting side effect of this was that we saw how physical infrastructure changes affect the results. For example, the deployment of an optical fiber from one point to another has improved the upload time by almost 3x.
