    Abstract: Embodiments may include a load balancer configured to, for a given packet received from a remote client, select a host computer of a plurality of host computers according to a load balancing protocol, the selection based on load information updates received from the plurality of host computers. Each load information update may indicate a measure of the respective host computer's capacity to service additional connections with remote clients. The load balancer may provide the given packet to the selected host computer for processing by an application component on the selected host computer, and subsequent to determining that a specific application component on one of the plurality of host computers does not have capacity for additional connections based on the load information updates, continue to send packets for existing connections serviced by the specific application component to the respective host computer without sending packets for new connections to that host computer.

    Abstract: Methods, apparatus, and computer-accessible storage media for controlling export of snapshots to external networks in service provider environments. Methods are described that may be used to prevent customers of a service provider from downloading snapshots of volumes, such as boot images created by the service provider or provided by third parties, to which the customer does not have the appropriate rights. A request may be received from a user to access one or more snapshots, for example a request to export the snapshot or a request for a listing of snapshots. For each snapshot, the service provider may determine if the user has rights to the snapshot, for example by checking a manifest for the snapshot to see if entries in the snapshot manifest belong to an account other than the customer's. If the user has rights to the snapshot, the request is granted; otherwise, the request is not granted.

    Abstract: Embodiments may include a load balancer that receives a request packet sent by a remote client to an original destination address of multiple network addresses serviced by the load balancer, and selects according to a load balancing protocol, a host computer of a plurality of host computers to process the request. The load balancer may, from among a plurality of ports on the selected host computer, select a particular port having a one-to-one association with the original destination address, the association specified by mapping information accessible to the load balancer, and send the request packet to the selected port on the selected host computer. The mapping information accessible to the selected host computer specifies a one-to-one association between the selected port and the original destination address. Sending the request packet to the selected port conveys that address to the selected server without that address being included in that packet.
