Abstract: A container orchestration platform manages a plurality of instances of resources including a first custom resource and a second custom resource. An API server of the container orchestration platform receives a request to delete an instance of the second custom resource; determines whether instance data associated with the instance of the second custom resource has a backreference identifying an instance of the first custom resource, the backreference indicating the instance of the first custom resource is dependent on the instance of the second custom resource; and in response to determining that the instance data has the backreference to the instance of the first custom resource, bypasses deletion of the instance of the second custom resource.

Abstract: A computing system comprising a memory and processing circuitry may perform the techniques. The memory may store time series data comprising measurements of one or more performance indicators. The processing circuitry may determine, based on the time series data, an anomaly in the performance of the network system, and create, based on the time series data, a knowledge graph. The processing circuitry may determine, in response to detecting the anomaly, and based on the knowledge graph and a machine learning (ML) model trained with previous time series data, a causality graph. The processing circuitry may determine a weighting for each edge in the causality graph, determine, based on the edges in the causality graph, a candidate root cause associated with the anomalies, and determine a ranking of the candidate root cause based on the weighting. The analysis framework system may output at least a portion of the ranking.

Abstract: An example network system includes processing circuitry and one or more memories coupled to the processing circuitry. The one or more memories are configured to store instructions which cause the system to obtain telemetry data, the telemetry data being associated with a plurality of applications running on a plurality of hosts. The instructions cause the system to, based on the telemetry data, determine a subset of applications of the plurality of applications that run on a first host of the plurality of hosts. The instructions cause the system to determine a subset of firewall policies of a plurality of firewall polices, each of the subset of firewall policies applying to at least one respective application of the subset of applications. The instructions cause the system to generate an indication of the subset of firewall policies and send the indication to a management plane of a distributed firewall.

Abstract: An example network system includes processing circuitry and one or more memories coupled to the processing circuitry. The one or more memories are configured to store instructions which, when executed by the processing circuitry, cause the network system to receive connection data related to an egress connection of an application service of an application. The instructions cause the network system to analyze the connection data to determine that the egress connection is an anomalous connection. The instructions cause the network system to generate a notification indicative of the egress connection being an anomalous connection and send the notification to a computing device.

Abstract: Techniques are described for determining the energy usage of a data center and invoking one or more actions to improve the energy usage of the data center. For example, a computing system may obtain energy usage data of a data center deploying an application. The computing system may also determine, based on a comparison of the energy usage data of the data center deploying the application to a percentage of energy provided by one or more renewable energy sources to the data center, a green quotient of the application that specifies a value that indicates whether the data center deploying the application is energy efficient. The computing system may further invoke, based on the green quotient of the application that specifies a value that indicates the data center deploying the application is not energy efficient, an action to improve energy usage of the data center deploying the application.

Abstract: In general, this disclosure describes techniques that enable a network system to perform application-aware active measurement for monitoring network health. The network system includes memory that stores a topology graph for a network. The network system includes processing circuitry that may receive an identifier associated with an application utilizing the network for communications, and determine, based on the topology graph and the identifier, a subgraph of the topology graph based on a location, in the topology graph, of a node representing a compute node that is a host of the application. The processing circuitry may next determine, based on the subgraph, a probe module to measure performance metrics associated with the application, and for the probe module, generate configuration data corresponding to the probe module. The processing circuitry may output, to the probe module, the configuration data.
