The technology provides for live migration from a first cluster to a second cluster. For instance, when requests to one or more cluster control planes are received, a predetermined fraction of the received requests may be allocated to a control plane of the second cluster, while a remaining fraction of the received requests may be allocated to a control plane of the first cluster. The predetermined fraction of requests are handled using the control plane of the second cluster. While handling the predetermined fraction of requests, it is detected whether there are failures in the second cluster. Based on not detecting failures in the second cluster, the predetermined fraction of requests allocated to the control plane of the second cluster may be increased in predetermined stages until all requests are allocated to the control plane of the second cluster.

A generation identifier is employed with various systems and methods in order to identify situations where a workload has been reassigned to a new node and where a workload is still being processed by an old node during a failure between nodes. A master node may assign a workload to a worker node. The worker node sends a request to access target data. The request may be associated with a generation identifier and workload identifier that identifies the node and workload. At some point, a failure occurs between the master node and worker node. The master node reassigns the workload to another worker node. The new worker node accesses the target data with a different generation identifier, indicating to the storage system that the workload has been reassigned. The old worker node receives an indication from the storage system that the workload has been reassigned and stops processing the workload.

Disclosed embodiments are directed at systems, methods, and architecture for operating a control plan of a microservices application. The control plane corresponds with data plane proxies associated with each of a plurality of APIs that make up the microservices application. The communication between the data plane proxies and the control plane enables automatic detection of service groups of APIs and automatic repair of application performance in real-time in response to degrading service node conditions.

Systems, methods, and devices for implementing destination and source group-based routing are disclosed herein. Systems include transmitters configured to transmit media streams that are packetized streams of data. Each of the transmitters is implemented on one of a first plurality of physical nodes included in a first node cluster. The transmitters include encoders configured to generate the plurality of media streams. Systems include receivers configured to receive the media streams. Each of the receivers is implemented on one of a second plurality of physical nodes included in a second node cluster. The receivers include decoders configured to receive and decode the media streams. Systems include a controller configured to generate a first grouping for each node cluster based on node characteristics and cluster parameters, generate a second grouping for each node cluster based on grouping parameters, and route the media streams based on the first grouping and second grouping.

A computing device includes an interface to communicate with a dispersed storage network (DSN), a memory, and a processing module. The computing device receives, from another computing device, a write queue entry request to facilitate storage of one or more queue entries of a queue in a set of storage units (SUs). The computing device dispersed error encodes at least a portion of the write queue entry request to generate a set of queue entry encoded slices (QEESs). The computing device generates a write request, based on the write queue entry request, that includes a slice name corresponding to a QEES of the set of QEESs that includes a queue entry identifier (ID) field that includes a timestamp field and/or an entry number of the write queue entry request. The computing device transmits the write request to the set of SUs to facilitate distributed storage of the set of QEESs.

A method comprises receiving, at a system from an application server, a request for a service, the system comprising two or more global session databases, and the request associated with a session; identifying among the two or more global session databases, a first global session database to fulfill the request based on a criteria; storing, by the application server, the session at the first global session database; and transmitting, by the session, data associated with the request for the service in accordance with a configuration table. Additional methods, systems, and non-transitory computer-readable media or computer program products provide similar or alternative functionality.
