Abstract:

A control-plane component of a virtual network interface (VNI) multiplexing service assigns one or more VNIs as members of a first interface group. A first VNI of the interface group is attached to a first compute instance. Network traffic directed to a particular endpoint address associated with the first interface group is to be distributed among members of the first interface group by client-side components of the service. The control-plane component propagates membership metadata of the first interface group to the client-side components. In response to a detection of an unhealthy state of the first compute instance, the first VNI is attached to a different compute instance by the control-plane component.

International Classification:

G06Q 30/06
G06N 99/00

Abstract:

A server receives a request for a service from a first user that defines a location for the service and a category of the service. A first stage of matching is performed that includes determining second users that match the location and category. A second stage of matching is performed that includes performing for each second user: computing a first value that quantifies an attractiveness of the request to that second user, computing a second value that quantifies a likelihood of the first user selecting that second user to fulfill the request, and computing a third value based at least in part on the computed first and second values. A request for the service is transmitted to at least some of the second users whose computed third value exceeds a first threshold value.
