Various systems and methods for partitioning a directory while allowing concurrent access to the directory. For example, a method involves receiving a request to partition an original directory that comprises a plurality of entries and creating a partitioned directory in response to receiving the request. The method also involves distributing the entries from the original directory to the partitioned directory. Distributing the entries involves sequentially copying each entry from the original directory to the partitioned directory. The method also involves performing an operation on the original directory while the entries are being distributed. Performing the operation involves accessing and/or updating the original directory.

Technologies are described herein for reducing network traffic when replicating memory data across hosts. The memory data stored in a main memory of the host computer is replicated to a main memory of a second host computer. Memory data from the local data storage of the second host computer that is a duplicate of memory data from the main memory is identified. Instead of sending the memory data from the main memory that is duplicated, the duplicated memory is copied from the local storage to the main memory of the second host computer.

Systems and methods for establishing, configuring, and operating multi-access edge computing (MEC) services and service consumption through zoning hosts in multi-vendor or multi-system environments. An apparatus operating as a MEC orchestrator to manage services consumption using zones is configurable to perform operations to: receive, from an application executing at a host, a request for a list of services and corresponding proximity zones; in response to receiving the request for the list of services, query a plurality of hosts for performance metrics of respective services offered from the plurality of hosts, the respective services to be used by the application executing at the host; construct a zone map, the zone map maintaining a mapping between the application and the plurality of hosts based on the performance metrics; and manage migration of the application or a service of the respective services, based on the zone map, to ensure QoS of the application.

The present disclosure involves systems, software, and computer implemented methods for providing an asynchronous transport channel for OData data using web sockets. One example method includes upgrading a HTTP connection to a web socket connection in response to an upgrade request. The web socket connection is maintained, after the upgrading, for receipt of subsequent web socket requests. An OData request is received, from a consuming application, over the web socket connection. The OData request is translated to a format used by an OData runtime environment and sent to the OData runtime environment. A response to the OData request is received from the OData runtime environment. The response is incorporated into a web socket message. The web socket message is sent to the consuming application, over the web socket connection, in response to the OData request, with the web socket connection remaining open after the web socket message is sent.

Synchronizing metadata among storage systems synchronously replicating a dataset, where synchronizing the metadata includes: receiving, at a first storage system of the storage systems, an I/O operation directed to the dataset; determining, in dependence upon the I/O operation, a metadata update describing a mapping of segments of content to a virtual address within a storage object, wherein the storage object includes the dataset; and synchronizing metadata on a second storage system of the storage systems by sending the metadata update to the second storage system to update a metadata representation on the second storage system in accordance with the metadata update.

Binding a public cloud account and a personal cloud account is described. A pre-approval list indicates that a user's public cloud account and personal cloud account are approved for binding. A copy of the pre-approval list is stored on the personal cloud device; another copy is stored on the public cloud service. The user logs into the public cloud account using a client device. Based on the pre-approval list stored on the public cloud service, the client device obtains information identifying the user's personal cloud account. The personal cloud device verifies the pre-approval of the binding based on the pre-approval list stored on the personal cloud device. The personal cloud device transmits a verification to the public cloud service. Each of the public cloud service and the personal cloud device stores information indicating the binding.

Systems, methods, techniques and apparatuses of asynchronous communication is distributed systems are disclosed. One exemplary embodiment is a method determining, with a plurality of agent nodes structured to communicate asynchronously in a distributed system, a first set of iterations including an iteration determined by each of the plurality of agent nodes; determining, with a first agent node of the plurality of agent nodes, a local vector clock; receiving, with the first agent node, a first iteration of the first set of iterations and a remote vector clock determined based on the first iteration; updating, with the first agent node, the local vector clock based on the received remote vector clock; and determining a first iteration of a second set of iterations based on the first set of iterations after determining all iterations of the first set of iterations have been received based on the local vector clock.
