A standby site is periodically synchronized to a primary site. The synchronizing includes copying blocks of a source volume at the primary site that have changed since a last synchronization to the standby site, and a bitmap specifying locations of the changed blocks. A synthetic full copy of the source volume is generated at the standby site. The synthetic full backup is validated by using the bitmap to identify locations on the synthetic full backup to verify. These locations correspond to the changed blocks. A progress of the validation is tracked. A user can specify a threshold percentage value of data that upon being validated indicates that the standby site is ready to assume production operation from the primary site. A readiness of the standby site to assume production operation is reported based on the progress of the validation and the threshold percentage value.

A method, system and computer program product for maintaining state synchronization of an application between computing devices and maintaining state synchronization of common information between different applications. A server receives a request from a client device to access a shared state scope. A shared state scope is a data store that physically resides on the server, where the data store stores state information. The state information stored in these scopes can be shared among multiple instances of an application residing on multiple client devices. Furthermore, the state information may include common information that is shared among different applications. Upon the server providing access to the requested scope, the server receives an update to the state information stored within the requested scope from the requesting client device. The server then notifies other client devices regarding the update to the state information that have access to the shared state scope.

A method for migrating memory data of a virtual machine, and a related apparatus, and a cluster system are provided. The method includes: obtaining a data sending request for sending memory data of a first virtual machine, where the request includes an identity of the first virtual machine and a PFN of the memory data that is requested to be sent; querying a correspondence information base according to the identity of the first virtual machine to obtain a correspondence of the first virtual machine; querying the correspondence of the first virtual machine according to the PFN of the memory data that is requested to be sent, so as to obtain a physical memory page address of the memory data; and sending, to a destination physical host by using an RDMA network adapter, memory data stored at the physical memory page address of the memory data.

The disclosed systems and methods enable an application to start operating and servicing users soon after and during the course of its backup data being restored, no matter how long the restore may take. This is referred to as “instant application recovery” in view of the fact that the application may be put back in service soon after the restore operation begins. Any primary data generated by the application during “instant application recovery” is not only retained, but is efficiently updated into restored data. An enhanced data agent and an associated pseudo-storage-device driver, which execute on the same client computing device as the application, enable the application to operate substantially concurrently with a full restore of backed up data. According to the illustrative embodiment, the pseudo-storage-device driver presents a pseudo-volume to the file system associated with the application, such that the pseudo-volume may be used as a store for primary data during the period of “instant application recovery.”

The present disclosure provides a system and method for online brand continuity. Online brand continuity can include a number of Internet or intranet access points via which one or more network addresses can be advertised. A client can be provided with availability of a business image application via at least one of the Internet or intranet access points.

Technologies for contention-aware cloud compute scheduling include a number of compute nodes in a cloud computing cluster and a cloud controller. Each compute node collects performance data indicative of cache contention on the compute node, for example, cache misses per thousand instructions. Each compute node determines a contention score as a function of the performance data and stores the contention score in a cloud state database. In response to a request for a new virtual machine, the cloud controller receives contention scores for the compute nodes and selects a compute node based on the contention score. The cloud controller schedules the new virtual machine on the selected compute node. The contention score may include a contention metric and a contention score level indicative of the contention metric. The contention score level may be determined by comparing the contention metric to a number of thresholds. Other embodiments are described and claimed.

An information processing apparatus communicating with a management apparatus, in which an import instruction of setting information is received and, if the information processing apparatus is an apparatus which synchronizes the setting information with the management apparatus, predetermined setting information is set as a non-import-target among import target setting information.

The order of migrating virtual computing instances from a private data center to a public cloud is optimized using a TSP solver. The method of migrating a plurality of virtual computing instances that are in communication with each other within a private data center to a public cloud includes the steps of assigning, for each different pair of virtual computing instances, a numerical value that represents an amount of data transmission between the pair over a predetermined period of time, determining a recommended order of migration for the virtual computing instances based on the assigned numerical values, and migrating the virtual computing instances according to the recommended order.
