If they are running from AWS to AWS, it's going over the AWS backbone.
- toredash 5y agoIs that true? I thought you had to do VPC peering for regions to use those backbones
- ignoramous 5y agoYeah, you need any among VPC Peering, Private Link, Transit Gateway for inter-region (global) backbone connections.
- kitteh 5y agoInter region traffic always goes over the backbone (this includes EIP to EIP). This also includes going from EC2 to any service like S3 in another region. Except China. China to rest of world is not via backbone.
- toredash 5y agoI don't see this in the docs
- geoduck14 5y agoChina is super special. Stay out of that region unless you have a special China reason to go in there.
- kitteh 5y agoIt should be. Also this was covered in a reinvent presentation about the aws network.
- ignoramous 5y agoI doubt unless you're using VPC peering, Transit Gateway, or Private Link that it would be the case that user-generated traffic between regions (for ex, between EC2 instances in Dublin and Sydney) is automatically routed through their backbone. Can you point to the re:Invent presentation? Genuinely curious.
- virtuallynathan 5y agoIt really is, for all AWS-AWS traffic barring Beijing and Ningxia. src: I worked in AWS networking for 2.5 years here's DUB->SYD: HOST: amazon02.ring.nlnog.net Loss% Snt Last Avg Best Wrst StDev 1.
