Abstract: A controller provides dynamic load distribution in a multi-tier distributed platform. The controller may receive a request at a first Point-of-Presence (“PoP”) with a first set of resources. The first PoP may be part of a distributed platform with several distributed PoPs at different network locations. The controller may classify the requested task with a priority, may determine resource availability, and may dynamically distribute the request by (i) providing the request to the first set of resources in response to classifying the task with a high first priority, and determining the availability of the first set of resources to be less than a threshold, and (ii) providing the request to a second PoP in response to classifying the task with a lower second priority, and determining the availability of the first set of resources to be less than the threshold.

Abstract: Example techniques relate to changing a playback device mode based on a device base. In an example implementation, a first playback device operates in a first mode where it is connected to a first network and plays back audio content while in the first mode. The playback device detects connection of the first playback device to a device base and while the first playback device is on the device base, detects connection to a second network. The first playback device switches from operating in the first mode to operating in a second mode. The first playback device forms a stereo pair configuration with a second playback device over the second network in the second mode. While in the second mode, the first playback device plays back a first channel of audio content in synchrony with the second playback device playing back a second channel of the audio content.

Abstract: Disclosed embodiments provide for collaborative access to a distributed data structure. Operations such as inserting, deleting, and annotating are performed by various clients participating in the collaboration. A serialization service enforcing a single order of these operations and ensures the operations and order are communicated to all of the clients participating in the collaboration. Once all clients have acknowledged particular operations, this information is also communicated to all of the clients, such that the clients may perform maintenance activities on the collaboration data structures. The result is a rolling collaboration window shared by all of the clients of the collaboration, with a bottom of the collaboration window defined by a lowest ordered operation not yet acknowledged by all clients of the collaboration, and a highest ordered operation as assigned by the serialization service.

Abstract: A method for normalizing leaf nodes of a weighted tree for use in a scheduler is disclosed. In one embodiment, such a method includes obtaining a weighted tree structure having a root node and multiple downstream nodes. Each downstream node is assigned a weight value. The method assigns a global maximum number and a global minimum number to the root node. The method derives, from the weight values and the global maximum number and global minimum number, a maximum number and a minimum number for each downstream node. The method further assigns, to each leaf node of the downstream nodes, an absolute weight value that is related to at least one of its maximum number and its minimum number. The method schedules items associated with the leaf nodes based on the absolute weight values associated with the leaf nodes. A corresponding system and computer program product are also disclosed.

The portion of the real-time media application being redirected includes provisioning information directed to a remote media server. A network location service provides provisioning information directed to a nearby media server.

Abstract: For a managed network, some embodiments provide a method for a set of service nodes in an active-active service node cluster in conjunction with a host computer hosting a destination data compute node (DCN) to improve the efficiency of directing a data message to a service node storing state information for the flow to which the data message belongs. a first service node receives a data message in a particular data message flow for which it does not maintain state information. The first service node then identifies a second service node to process the data message and forwards the data message to the second service node. The second service node sends state information for the particular data message flow to the first service node, for the first service node to use to process subsequent data messages in the particular data message flow.

Abstract: Techniques for managing fault domains using cells are described. An area of a provider network may be divided into multiple cells, with each cell representing a different fault domain of the area of the provider network. A customer can provide domain definitions for their service or application and a cell management service can use the domain definitions to place the infrastructure and compute resources underlying the customer's application or service in appropriate cells within an area of the provider network. In some embodiments, the domain definitions may be account-based, where the domain definition may be to place resources in different fault domains depending on the account they are associated with. Alternatively, the customer may tag resources with an identifier such that resources tagged with a first identifier may be placed in a first cell while resources tagged with a second identifier may be placed in a second cell.

Abstract: Determining microservice placement to minimize response time in a network is provided. A set of resources utilized by a microservice during operation is identified based on inspecting a configuration file and code of the microservice. A deployed location within the network of each resource is determined. A relative weight value is assigned to each resource indicating a relative significance of each resource to the microservice during operation. A weighted-average response time is determined for each data center in a set of possible data centers to deploy the microservice based on the relative weight value assigned to each resource and a determined distance value measured by response time between the deployed location of each resource and each possible data center in the set. A data center in the set of possible data centers is selected to deploy the microservice based on the data center having a lowest determined weighted-average response time.

Abstract: A monitoring system using agents to dynamically collect state information at controllable intensity levels from components of systems. The system receives state information collected by an agent at a particular intensity level, and processes the state information to determine an updated intensity level for collecting state information by the agent, or by some other agent. The state information may include data indicating the performance of one or more components, such as process response times or other metrics. The intensity level for collecting further state information can be increased when, among other things, previously collected state information indicates more detailed monitoring for the component is appropriate. The intensity level for collecting further state information can be decreased when, among other things, previously collected state information indicates continued expected behavior.
