Abstract: Various embodiments relate to cooperative resource reservation for concurrent virtual environments on a shared host. In an embodiment, a method involves concurrently executing multiple virtual environments, including a first and a second virtual environment, on the shared host. A host execution environment issues a request on behalf of the first virtual environment to reserve a resource, with the request containing identifying information specific to the first virtual environment. The identifying information included in the reservation allows the controller of the resource to be identified despite the virtual environments sharing the initiator identity of the host.

Abstract: Pod-level snapshot replication, including: generating a snapshot of a data set included in a source pod of a storage system; and replicating the snapshot of the data set to a target pod different than the source pod.

Abstract: A stream of events is received, where individual events within the stream of events are received out-of-order. The events from the stream of events are ordered. Whether a predetermined collection of events have occurred within a predetermined period of time is determined. Responsive to determining that the predetermined collection of events have occurred within the predetermined period of time, an action associated with the predetermined sequence of events is initiated.
