Metric management techniques in a multi-cluster computing environment are disclosed. For example, a method obtains a set of metrics collected from one or more computing clusters of a distributed computing environment, wherein the set of metrics are associated with one or more processes that are executable on the one or more computing clusters. The method computes one or more metric importance values for the set of metrics based on one or more processing criteria. The method sends the one or more metric importance values to at least one computing cluster of the one or more computing clusters to enable the at least one computing cluster to adapt a collection frequency of at least one metric of the set of metrics. Such adaptation, by way of example, can be based on the metric importance and resource availability.

Methods, systems, and computer program products for service-to-service scheduling in container orchestrators are provided herein. A computer-implemented method includes reserving, by a network orchestrator, network resources requested between a plurality of services, wherein each of the services is implemented as one or more replicas running on a set of nodes of a cluster, managed by the network orchestrator, that use the network resources to serve incoming requests to the plurality services; monitoring utilization of the network resources; and scheduling, by the network orchestrator based on the monitoring, one or more new replicas of the plurality of services and the incoming requests to the plurality of services in a collaborative manner to increase at least one network performance characteristic.

Service-to-service scheduling in container orchestrators

One embodiment provides a method, including: producing, for each of a plurality of containers, a resource profile for each thread in each of the plurality of containers; identifying, for each of the plurality of containers and from, at least in part, the resource profiles, container dependencies between threads on a single of the plurality of containers; determining service dependencies between threads across different of the plurality of containers; scheduling, based upon the container dependencies and the service dependencies, threads to cores, wherein the scheduling is based upon minimizing thread processing times; and publishing the container dependencies and the service dependencies on a registry of the node clusters.

Services thread scheduling based upon thread tracing

Edge application deployment in a network is provided. The network includes a plurality of edge sites with edge computing infrastructure. Edge application deployment is performed, including deploying a pseudo application instance (pApp) of the edge application at each edge site of a first group of edge sites of the plurality of edge sites, and deploying a real application instance (rApp) of the edge application at each edge site of a second group of one or more edge sites of the plurality of edge sites. The pApp is a lightweight, application-specific instance of the rApp with less application functionality than the rApp. Further, the first group of edge sites is larger than the second group, and a user device interaction with the edge application is through a selected pApp of the first group of edge sites to an rApp of the second group.

An ensemble of autoencoder models can be trained using different seeds. The trained ensemble of autoencoder models can be run on new time series data to generate a prediction associated with the new time series data. The new time series data can include multiple dimensions per time step. Reconstruction errors can be determined for the prediction. Dimensions having highest reconstruction errors can be selected among the multiple dimensions based on a threshold. The prediction can be segmented based on bursts of the reconstruction errors over time, where temporal segments can be obtained. At least one common pattern including a set of dimensions among the selected dimensions across the temporal segments can be obtained to represent a failure fingerprint.

An example operation may include one or more of receiving, by an orderer node, a merge channels transaction for a plurality of channels that includes a modification policy for the plurality of the channels, verifying, by the orderer node, the merge channels transaction based on the modification policy, executing, by the orderer node, the merge channels transaction to generate a merge block, and providing the merge block to participating nodes for a merger of the plurality of the channels into a new channel.

Splitting and merging of storages

One embodiment provides a computer implemented method, including: receiving an application to be deployed on a container-based environment; obtaining a specification for the application including information regarding a portion of the application contained within a given container; extracting portion information corresponding to connections between different portions of the application and interferences between different portions of the application; identifying affinity indicators and anti-affinity indicators for the portions of the application, wherein the affinity indicators are based upon the connections between different portions of the application and wherein the anti-affinity indicators are based upon the interferences between different portions of the application; and constructing affinity rules and anti-affinity rules for the containers by combining the affinity indicators to construct affinity rules and combining the anti-affinity indicators to construct anti-affinity rules.
