Systems and methods are described to enable the load-balanced use of globalized network addresses, addressable throughout a network to access a network-accessible service. A set of global access points are provided, which advertise availability of the globalized network addresses. On receiving a request to access a network-accessible service, a global access point can select an endpoint for the service from among a number of data centers, based on a desired distribution of traffic among the data centers. The access point then forwards the traffic to the selected endpoint. In one embodiment, the access point applies network address translation to enable the traffic to be routed to the endpoint without terminating a connection at the endpoint. The access point may use a variety of techniques to ensure resiliency of the network and knowledge of available endpoints.

Load balanced access to distributed endpoints using anycasted global network addresses and network address translation

Systems and methods are described to enable the load-balanced use of globalized network addresses, addressable throughout a network to access a network-accessible service. A set of global access points are provided, which advertise availability of the globalized network addresses. Globalized network addresses can be divided among different pools, and each service can be associated with addresses of more than one pool. To increase resiliency, access points can advertise different pools of addresses to different neighboring devices, creating different pathways to reach the access point. If an error occurs on a neighboring network, a client can try to access the service via an address of a different pool, which can be expected to be routed through a different neighboring network, thus enabling the client to reach the access point.

Load balanced access to distributed endpoints using resiliently advertised global network addresses

Systems and methods are described to enable the load-balanced use of globalized network addresses, addressable throughout a network to access a network-accessible service. A set of global access points are provided, which advertise availability of the globalized network addresses. The access points enable rapid use of connection-oriented communication sessions by conducting an initialization phase of the sessions locally on the access point. Session context information is then handed off to an endpoint for the service, which can provide the service through the already-established sessions. To avoid breaking sessions due to changes in network routing, each access point can apply a uniform selection criteria for endpoints, such that if client traffic is routed to a different access point, that access point redirects the traffic to the same endpoint previously servicing the traffic via an established session.

Load balanced access to distributed endpoints using global network addresses and connection-oriented communication session handoff

Systems and methods are described to enable the load-balanced use of globalized network addresses, addressable throughout a network to access a network-accessible service. A set of global access points are provided, which advertise availability of the globalized network addresses. On receiving a request to access a network-accessible service, a global access point can select an endpoint for the service from among a number of data centers, based on a desired distribution of traffic among the data centers. The access point is responsive to scaling that might occur at endpoints by periodically retrieving updated configuration information for the endpoints, enabling the access point to nimbly respond to changes in endpoints for the service.
