Amazon Simple Storage Service (Amazon S3) is an object storage service provided by AWS. An Amazon S3 network downlink and latency test was recently run across the APAC regions (excluding the two Chinese-only regions). Here is a snapshot of that test:
This test was run from Sydney, Australia. The AWS ap-southeast-2 region, which is also in Sydney, returned the fastest downlink and best latency test results over the other APAC regions. This clearly illustrates the advantage of connecting to your nearest storage access points.
You can run this same test in Cloud Harmony using thislink.
