A checkpoint trigger initiating a synchronization of a first virtual machine with a second virtual machine may be received, the first virtual machine being executed with at least a first virtual processor and a second virtual processor. The first virtual processor may be paused, while the first virtual machine is allowed to continue executing, using the second virtual processor. The synchronization may be executed, including transferring memory pages of the first virtual machine for storage by the second virtual machine, and the first virtual processor may be released and execution of the first virtual machine may be resumed, using the first virtual processor and the second virtual processor.

Cloud-enabled, distributed and high-availability system with virtual machine checkpointing

Implementations of the present disclosure are directed to enabling data transfer between data producers and data consumers. Implementations include generating a data structure, the data structure including a lockless spin buffer (LLSB), the LLSB including two or more lockless components, each of the two or more lockless components including a plurality of elements to be written to and read from, providing one or more write pointers to enable one or more data producers to write to each of the two or more lockless components, and providing one or more read pointers to enable one or more data consumers to read from each of the two or more lockless components, the one or more data producers being able to write to the LLSB concurrently with the one or more data consumers being able to read from the LLSB.

Lockless spin buffer

A message handler may receive a plurality of messages associated with a plurality of events, the events having a temporal relationship to one another. A header inspector may extract latency information from the plurality of messages, the latency information characterizing a transmission duration experienced by each message in traveling from the one or more source nodes through the network. A window manager may correct a disruption in the temporal relationship between at least two events of the plurality of events, the disruption including relative differences in the transmission duration experienced by the at least two events, including relating the at least two events to a time window for processing the at least two events. An event processor may process the at least two events relative to the time window.

Dynamic adaptations for network delays during complex event processing

A system may include an address manager configured to map a data item including a plurality of attributes to a blocked Bloom filter (BBF) of a plurality of blocked Bloom filters. The system also may include a blocked Bloom filter (BBF) generator configured to map each attribute of the plurality of attributes to a corresponding block of the blocked Bloom filter.

Dynamic, hierarchical bloom filters for network data routing

Operating parameters of one or more software appliances may be set at a configuration manager. Compliance of the one or more software appliances with license terms may be maintained at a license manager. Communications may be executed between the license manager and the configuration manager to maintain compliance of the operating parameters with the license terms. A user interface may be provided for administration of the one or more software appliances therewith, the administration including deployment of the one or more software appliances, the license manager, the configuration manager, and a deployment manager within a system landscape. Communication may be executed between the license manager and the deployment manager to maintain compliance of the administration of the one or more software appliances with the license terms. Communication may be executed between the deployment manager and the configuration manager to manage the deployment relative to the operating parameters.

Flexible appliance hosting with coordination of deployment, licensing and configuration

A page scanner may be configured to identify, during a live migration of a virtual machine including a transfer of a plurality of memory pages from source hardware resources to destination hardware resources, a candidate memory page of the plurality of memory pages to include in the transfer while at least one operation of the virtual machine continues to execute. A fingerprint comparator may be configured to compare a candidate page fingerprint of the candidate memory page to existing page fingerprints of existing memory pages stored using the second hardware resources, and further configured to determine, based on the comparing, that a duplicate of the candidate page is included within the existing memory pages. A duplicate page handler may be configured to facilitate continued execution of the virtual machine using the duplicate of the candidate page and the second hardware resources.
