Abstract: A computer implemented method includes distributing a plurality of prediction models, where each of a plurality of clients initially includes at least one associated prediction model from the plurality of prediction models, among all of the plurality of clients to provide each of the plurality of clients with each of the plurality of prediction models. The plurality of prediction models is evaluated on at least a portion of a local dataset resident on each of the plurality of clients to output a quantification indicating how each of the prediction models fit at least the portion of the local dataset of each of the plurality of clients. An ensemble model is generated by applying weights to each of the plurality of prediction models based on a value, a gradient, and a Hessian matrix of a user-defined objective.

Abstract: A method is provided of using a set of servers to provide deferential services that have a pre-negotiated time for notice to release the servers. The method includes defining a virtual checkpoint frame interval that is constrained to a duration of up to half of the pre-negotiated time for notice to release the servers. The method includes, responsive to an end of the interval, (i) writing, to a shared state database, a state of processing of the packets and transactions occurring during the interval that are processed by a current one of the servers, and (ii) releasing the packets and transactions occurring during the interval. The method includes copying the packets and transactions occurring during the interval, and the state, from the current server to another server for subsequent processing, responsive to an indication of an instance loss on the current server.

Abstract: A method includes configuring worker services to operate in a stateless manner and providing support services that enable the worker services to operate in the stateless manner. The support services include (i) a management service for providing notifications of server removal and addition, (ii) a state maintenance service for maintaining state information in a central location, and (iii) a load balancer service for distributing requests among worker services. The method includes altering a number of servers allocated to at least one worker service, responsive to a notification from the management service. A private protocol is used between the worker services and load balancer service (a) to send, from the worker services to the load balancer service, a respective pointer to the state information associated with the requests, and (b) to include the respective pointer in the requests when any of the requests are forwarded to any worker service.

Abstract: Name based Internet of Things (IoT) discovery includes receiving domain name system (DNS) events. An Internet Protocol (IP) address to name mapping is built based on the DNS events. A data communication event occurring in a computer network is received. A destination IP address in the data communication event is mapped to a domain name by querying the IP address to name mapping. Whether the data communication event is associated with an IoT device is determined based on the domain name satisfying a rule.

Abstract: Systems, methods, and computer program products are disclosed for dynamically determining an optimal node of an overlay network for client attachment. An optimal node can be selected from a group of potential attachment nodes in the overlay network through which a client can establish a connection to the overlay network. Network parameter training data can be determined and used to train a network optimization model. Once trained, the network optimization model can be used to determine—based on network parameter data associated with the group of potential attachment nodes—the optimal node for the client to attach to. If a different node than a current attachment node is determined to be a new optimal node, a connection path can be established between this new optimal node and the client, and an existing connection path between the client and the previous optimal node can be terminated or simultaneously maintained.
