Apparatus for pattern-based migration of a source workload to a target workload at a target deployment which includes a discovery engine, a decision system, a deployment manager, a pattern deployment engine and a residual migration and remediation system. The discovery engine takes the source deployment as an input and discovers metadata associated with the deployed components of the source workload and the IT topology. The deployment manager in cooperation with the pattern deployment engine at the target determines a closest starting-point template to be used for pattern-based target workload deployment. The decision system receives the metadata from the discovery engine and in cooperation with the deployment manager makes a go or no-go decision whether to trigger pattern-based target workload. The residual migration and remediation system finds any undiscovered source workload components and deploys the undiscovered workload components to the target deployment by an image-based migration.

Pattern-based migration of workloads

A system, method and program product that provides a disaster recovery (DR) brokerage infrastructure. A system is described that includes: a network of intermediate storage nodes and peering points; and a brokerage manager that periodically evaluates a set of DR as a service (DRaaS) providers and selects a cost optimal DRaaS provider for a subscriber, wherein the brokerage manager replicates DR related data for the subscriber in an intermediate storage node prior to delivery to the cost optimal DRaaS provider.

Disaster recovery as a dynamic service

An approach is provided for transforming a base multi-tenant cloud into a white labeled cloud of a reseller. A first customer request for a cloud-based service is received by the reseller. Based on a central identification of a customer mapped to a local identification, a second request for the service is sent from the reseller to the cloud provider, indicating the customer is an apparent source of the second request and an apparent customer of the cloud provider, and obscuring the reseller being an actual source of the second request and the customer being an actual customer of the reseller. A customer notification is sent from the reseller, which white labels the provision of the service by indicating the reseller is an apparent provider of the service and obscuring the cloud provider being an actual provider of the service.

A memory medium includes one or more binary images and an update logic image. The memory medium selectively updates binary images having contiguous memory sectors erased before being rewritten. The update logic image includes instructions for determining whether an updating operation is to be performed and determining memory addresses of the memory medium at which a corresponding replacement image can be recorded. The instructions are also for erasing the determined memory addresses and writing the replacement image to the determined memory addresses.

Technology for selectively updating memory-resident images

Embedded devices typically have an operating system, one or more file-systems, as well as a bootloader and other data components resident in flash memory. During software development and testing, there is frequently a need to selectively update a combination of such images. The described technique organizes the images in the flash memory such that one can speed up the update process by eliminating relocation of existing images. A command-driven update mechanism provides a flexible process&#x2014;eg, one can upload the images back to a host, one can update the update code itself, etc. A start handshake is used that enables auto-detection of the embedded serial port that is used for the update.

A method comprises selecting bit positions for storing a digital watermark in digital audio data in time domain by choosing a spread function characterising the plurality of the selected bit positions, wherein the spread function comprises at least one Gaussian curve.

Selecting bit positions for storing a digital watermark

A method is disclosed for emulating a disk drive on flash memory, thus enabling one or more file-systems to be resident on flash memory. A list of data structures is maintained corresponding to certain sectors resident on flash memory. Certain characteristics of data access to those sectors are recorded and a weightage value is dynamically computed, which is used to select those sectors that remain cached. This weightage value is calculated so that it minimizes erases and speeds up writes to flash memory and also automatically detects flash memory sectors that hold critical meta-data information or frequently accessed files and gives preferential treatment to those sectors. The number of sector caches available to the device driver is configured depending on the memory available in the system.
