A distributed computing environment is provided with a system and method for supporting rare copy-on-write data access. The system operates a data structure in a read only pattern suitable for serving a plurality of read requests with reduced overhead. The system, upon receiving a write request, creates a copy of data to execute the write request. The system defers writing the mutated data back to the read-only data structure. The system thus allows for multiple mutations to be made to the copy of the data using a read/write access pattern. After a number of read-only requests are received, the mutated data is written back to the read-only data structure. A monitor counts read and write requests in order to reduce overall read/write overhead and enhance performance of the distributed data grid.

Systems and methods for performing backup operations and other secondary copy operations for mail servers, such as Exchange servers, are described. In some cases, the systems and methods perform multi-streaming backup and other copy operations using a single mailbox agent, which launches backup streams via a coordinator that determines when to launch streams, at what mailboxes (or folders) to launch the streams, and so on. The coordinator communicates with controllers at different machines (e.g., servers) to be backed up, and may assign streams, mailboxes, and so on, to the different controllers, which perform the backup operations for their assigned mailboxes and/or clients.

A power adapter configured to apply power to a device is disclosed. The power adapter comprises a switching module having a recess comprising a first set of contacts for receiving control signals, wherein the switching module comprises a switch for selectively applying power to a device based upon the control signals; and a control module removably coupled to the switching module and having a second set of contacts coupled to the first set of contacts of the switching module when the control module is attached to the switching module; wherein the switching module comprises a user interface element.

Aspects of the subject disclosure may include, for example, a method, including: receiving, by a processing system including a processor, a request to play content; querying, by the processing system, for matches between the content and a user library; receiving, by the processing system, recommendations for alternate content of the user library and associated cue points in the content; and presenting, by the processing system, portions of the content and presenting other portions of the content replaced with the alternate content at the associated cue points. Other embodiments are disclosed.

A method for distributing network function (NF) high availability (HA) topology information in a core network includes, at an NF repository function (NRF) including at least one processor, receiving, from a plurality of producer NFs in an NF set, NFRegister requests including NF HA topology information for the producer NFs. The method further includes registering the producer NFs and storing the NF HA topology information for the producer NFs. The method further includes receiving, from a consumer NF or service communication proxy (SCP), an NFDiscover request containing at least one service discovery parameter that corresponds to a service provided by the producer NFs. The method further includes responding to the NFDiscover request by generating an NFDiscover response, including, in the NFDiscover response, the NF HA topology information for the producer NFs, and transmitting the NFDiscover response to the consumer NF or SCP.

Techniques are described for providing service availability zones for computing-related services provided by a cloud provider network. According to some embodiments, the use of service availability zones enables users to achieve greater availability assurance for workloads sensitive to downtime or outages. The sensitivity of such workloads to downtime may be due to financial, regulatory, safety, or other reasons. Such availability-sensitive applications may in some cases be configured to run in multiple regions of a cloud provider network to increase their availability compared to running in a single availability zone. However, for some applications, the implementation of an application across multiple regions may not be feasible or desirable. The use of service availability zones provides user-visible fault domains within a single region of a cloud provider network, thereby enabling users to readily and reliably achieve application layer availability of approximately 99.999% for a service within a single region.
