    Abstract: A communication unit (2) communicates with a management apparatus directly or via another communication apparatus. A transfer control unit (4) performs processing of transferring a state change notification that has been transmitted from a first communication apparatus and indicates a state change of the first communication apparatus. A proxy calculation unit (6) performs, when a failure in communication has occurred at the side of the management apparatus, calculation for state management performed by the management apparatus using the state change notification. When a failure in communication has occurred, the transfer control unit (4) outputs a state change notification to the proxy calculation unit (6). When the failure in communication has been resolved, the transfer control unit (4) performs control so as to transmit the result of the calculation by the proxy calculation unit (6) to the management apparatus.

    Abstract: Examples provide a cloud server management controller configured to determine a network resource threshold and a cloud resource availability for a cloud server. The first resource availability is an amount of cloud network resources available in the cloud server within the network resource threshold. For each respective system of a plurality of local network systems, the controller determines a local resource usage and predicts a cloud resource requirement. The cloud resource requirement is an amount of cloud network resources required to provide a cloud-based equivalent of the respective system. The controller builds a model based on the cloud resource requirement for each respective system and the network resource threshold. The model defines a cloud migration priority for each of the plurality of local network systems. Based on the model, the controller generates a cloud migration timeline for sequentially migrating each respective system to the cloud server.

    Abstract: Techniques implemented by a cloud computing system for providing fallback capacity providers to ensure that infrastructure capacity required to run containerized services is available despite primary capacity providers experiencing a failure. Cloud providers offer container-management services that automate the management and scaling of containerized services of users. The container-management services are supported by capacity providers that manage the computing infrastructure on which the containerized services run (e.g., servers, VMs, etc.). However, there are times when a capacity provider is unable to provision capacity for containerized services, such as due to a large scale failure. Rather than leaving capacity requests unserved, the container-management service designates a fallback capacity provider that acts as a failover for provisioning requested infrastructure capacity. The fallback capacity providers have different provisioning paths than the primary capacity providers, and thus different availability postures and failure modes, to ensure resiliency in provisioning capacity for containerized services.

    Abstract: A network device may receive transport layer messages from an ingress network device, and may determine whether a quantity of resources required for processing the transport layer messages exceeds a threshold level of available resources of the network device. The network device may generate a transport layer path error message based on the quantity of resources required for processing the transport layer messages exceeding the threshold level of available resources. The network device may provide the transport layer path error message to the ingress network device to prevent the ingress network device from providing additional transport layer messages to the network device.
