Abstract: A system for load management in a shared address networking architecture includes a primary point-of-presence (POP) group of servers configured to serve content of a domain and that are each reachable at an address of a first IP address block and a secondary PoP group of servers configured to serve the content of the domain and that are each reachable at an address of a second IP address block. The system further includes a traffic management agent configured to reduce a total volume of incoming requests received by the primary PoP group for a period of time following a return of a first server in the primary PoP group of servers to an online state by selectively directing a first percentage of the incoming requests to the second IP address block instead of the first IP address block.

Abstract: A spring element includes a body, at least one leaf spring and a stress relieving section. The body includes at least one mounting section. The leaf spring includes a first portion and a second portion. The first portion being secured to the body and at least a part thereof extends angularly with respect to a plane of the body. The leaf spring exerts an urging pressure on an element disposed between the body and a housing as the body is mounted on the housing. The stress relieving section is formed along at least one lateral side of the leaf spring and proximal to the first portion.

Abstract: Techniques are described for securely managing computing resources in a computing environment comprising a computing service provider and a remote computing network. The remote computing network includes computing and network devices configured to extend computing resources of the computing service provider to remote users of the computing service provider. The network devices include a trusted network device that includes a root of trust. The trusted network device detects that a new device is communicatively coupled to a port on the trusted network device. The trusted network device determines that the new device is not authorized to access computing resources at the remote computing network. The port is isolated at the trusted network device.

Abstract: N nodes are assigned to a first layer of nodes having a first domain name server (DNS) anycast Internet Protocol (IP) address and a first fully qualified domain name (FQDN). M nodes are assigned to a second layer of nodes having a second DNS anycast IP address and a second FQDN. When a request to resolve the first FQDN for the first layer of nodes is received by a DNS of a node of the first layer and a load on the ES of the node is less than a threshold, the DNS handles the request by returning an edge server (ES) anycast IP address for the ES of the node. When the load on the ES is greater than the threshold, the DNS offloads the request by returning the second FQDN so that the second FQDN of the second layer is resolved to the second DNS anycast IP address.

Abstract: A Top of Rack (TOR) switch operating with a Software for Open Networking in the Cloud (SONiC) platform is implemented using commodity switch hardware and is configured to maintain or retrieve flow state information for incoming data flows in a load balancer. In one embodiment, an application-specific integrated circuit (ASIC) informs a user mode container flow state information for each incoming data flow. The user mode container informs the ASIC of any affected flows that may result pursuant to a modified distributed system (e.g., added, updated, or removed servers). In other embodiments, the ASIC may utilize remote direct memory access (RDMA) to retrieve flow state information maintained by a remote device or may utilize the RDMA to retrieve network address translation (NAT) information for incoming traffic. In each of the implementations, the integrity of the load balancing system is maintained when the distributed system of servers changes.

Abstract: An edge server node comprises an edge server, a DNS, and a load controller. The DNS is assigned to a layer of edge server nodes where each layer of edge server nodes has a DNS anycast IP address for the DNSs of that layer and a FQDN for that layer. The DNS either handles or offloads requests to resolve the FQDN for the assigned layer to balance the load on the edge server. A request is offloaded by returning the FQDN for another layer. The load controller monitors the load on the edge server and directs the DNS to offload requests to reduce the load on the edge server.

Abstract: Securely storing assets in a cloud computer storage service. Preparation to store assets for a user may comprise determining a location to store the assets, generating a write access signature, and sending the determined location and the signature to the user. A request is received from the user to store the assets. Such a request includes the assets, the location, and the signature. In response to receiving the request, a determination is made regarding the write access signature whether the request should be honored. When the request is honored, the assets are stored in the determined location and the write access signature is invalidated. Upon subsequent user requests to access the assets, short-term read access signatures are generated and provided to the user. The assets are written once per generated write access signature and reads are to be performed close in time to when short-term read access signatures are requested.

Abstract: Embodiments are directed to establishing caches that provide authoritative domain name system (DNS) answers to DNS requests. In one scenario, a computer system establishes a cache that stores authoritative DNS answers to DNS queries. The cache corresponds to a specified DNS zone that includes authoritative DNS answers for a subset of DNS queries. The cache is configured to store the authoritative DNS answers for at least a specified period of time during which the authoritative DNS answers are updatable. The cache then receives an update indicating that at least one cached DNS answer is out-of-date and the computer system purges the out-of-date DNS answer from the cache, ensuring that the cache continually provides authoritative DNS answers for DNS queries assigned to the specified DNS zone.

Abstract: An edge server node comprises an edge server, a DNS, and a load controller. The DNS is assigned to a layer of edge server nodes where each layer of edge server nodes has a DNS anycast IP address for the DNSs of that layer and a FQDN for that layer. The DNS either handles or offloads requests to resolve the FQDN for the assigned layer to balance the load on the edge server. A request is offloaded by returning the FQDN for another layer. The load controller monitors the load on the edge server and directs the DNS to offload requests to reduce the load on the edge server.
