Amazon patents private routes for cloud servers to talk to each other
Amazon has patented a method for creating private, internal paths between specific cloud servers and external services. This setup allows data to travel through a secure tunnel inside the provider's network instead of going out over the public internet.
In the filing’s own words
In accordance with a designation of a private alias endpoint as a routing target for traffic directed to a service from within an isolated virtual network of a provider network, a tunneling intermediary receives a baseline packet generated at a compute instance. The baseline packet indicates a public IP (Internet Protocol) address of the service as the destination, and a private IP address of the compute instance as the source. In accordance with a tunneling protocol, the tunneling intermediary generates an encapsulation packet comprising at least a portion of the baseline packet and a header indicating the isolated virtual network. The encapsulation packet is transmitted to a node of the service.
What exactly they claim (claim 1)
1. A computer-implemented method, comprising: establishing, in response to one or more programmatic requests directed to a provider network, a private endpoint which can be used to transmit, without utilizing the public Internet, requests to a service which is accessible via a public Internet Protocol (IP) address; receiving, at the provider network, an indication that a first subset of virtual machines of the provider network is permitted to utilize the private endpoint established within the provider network which can be used to transmit, without utilizing the public Internet, requests to the service which is accessible via the public IP address; and verifying, at the provider network prior to transmitting, to the service, a request which (a) originates at a particular virtual machine of the provider network and (b) is to be directed to the service via the private endpoint, that the particular virtual machine is a member of the first subset.
