Abstract: In one embodiment, a controller obtains data indicative of an application experience metric for an online application having application traffic conveyed via the network. The controller predicts the application experience metric that would result from a first edge router conveying its application traffic to the online application via a second edge router that is not currently connected to the first edge router via a tunnel, based on the obtained data. The controller makes a determination that the first edge router should route its application traffic to the online application via a tunnel between the first edge router and the second edge router, based on the predicted application experience metric. The controller causes a tunnel to be established in the network between the first edge router and the second edge router, whereby the first edge router routes its application traffic to the online application via the second edge router.

One method includes receiving, over a network at a server, a connection request from a client device; authenticating, by the server, the connection request from the client device; determining, by the server, a connection path for the authenticated client device based on the connection request; determining, by the server, whether the connection path for the authenticated client device is a new connection path based on the connection request; and storing, by the server, the connection path to a connection database in association with the authenticated client device when the connection path is determined to be new, the connection database including a plurality of connection paths between the client device and the server.

Abstract: Implementations are provided herein for encoding and transmitting streaming data from a client application to a server for storage without prior knowledge of the size of the streaming data. A header can be sent that includes a batch size chunk size. Raw streaming data can be packaged into the chunk. Chunks can be packaged and sent at any time prior to filling up with streaming data, by padding the chunk and including a footer that delineates the amount of raw stream data in the chunk. Chunks that are full can have a footer that delineates the entire chunk is raw stream data. It can be appreciated that you do not need to buffer data on the client side as chunks do not need to be full to send. Latency on processing streaming data can also be reduced by limited or eliminated buffering.

Abstract: Described are computing systems and methods configured to detect a small, but meaningful, anomaly within one or more metrics associated with a platform. The system displays visuals of the metrics so that a user monitoring the platform can effectively notice a problem associated with the anomaly and take appropriate action to remediate the problem. An operational visual includes a radar-based visual with a heatmap arranging metrics, and a node representing a state of the metrics. Moreover, the system uses an ensemble of unsupervised machine learning algorithms for multi-dimensional clustering of hundreds of thousands of monitored metrics. Via the visuals and the implementation of the machine learning algorithms, the described techniques provide an improved way of representing and simulating many metrics being monitored for a platform. Moreover, the techniques are configured to expose actionable and useful information associated with the platform in a manner that can be effectively interpreted.

Abstract: A state of resource allocation is represented as a matrix. Each intersection of a row and column of the matrix indicates a number of units of a resource being provided by a respective node and consumed by a respective client. The allocation is modeled using a characteristic equation of the matrix. The characteristic equation is applied to the matrix to find an eigenvalue indicating a degree of scale the allocation can tolerate. An eigenvector is found for the eigenvalue to determine a direction of scale. A prediction is made as to whether the current state can scale at least one of upwards or downwards by the eigenvector.
