Abstract: For disaster recovery involving a first site and a disaster recovery site, where at least a portion of management service metadata not isolated within the management service, a failover process is initiated, including creating an initial snapshot of the distributed metadata state. In a failback process, a representation is created of state changes for the management service and a delta description is calculated therefrom. The delta description is transmitted to the first site; and a reverse replica is created, at the first site, of all the workload components from the disaster recovery site. The delta description is played back to restore a distributed metadata state that existed in the disaster recovery site and to re-create it in the first site.

Abstract: A control unit is coupled to an infrared light source including at least an infrared light emitter. The infrared light source may be embedded in a wearable device. The control unit captures user preference and also receives current context associated with the wearable device and/or a user wearing the wearable device. The control unit determines automatically based on the current context meeting the user preference, whether to activate the infrared light source to emit infrared light or deactivate the infrared light source to stop emitting infrared light. Responsive to determining that the infrared light source is to be activated, the infrared light source is activated to emit the infrared light. Responsive to determining that the infrared light source is to be deactivated, the infrared light source is deactivated to stop emitting the infrared light.

Abstract: Embodiments of the present invention include methods, systems, and computer program products for packet forwarding. Aspects of the invention include receiving, from a source node, a first network queue in a set of network queues, wherein the first network queue includes one or more minimum network traffic performance requirements. A set of network paths is analyzed to determine a performance level for each network path and identify a first network path and a second network path with a performance level above the one or more minimum performance requirements of the first network queue. A determination is made that the first network path has a higher performance level than the second network path. Based at least in part on determining that the first network path has a higher performance level than the second network path, the first network queue is mapped to the first network path.

Abstract: A computer-implemented method includes: receiving, by a computing device, a template for creating a virtual machine (VM) instance; separating, by the computing device, the template into a repeated portion and a unique portion; determining, by the computing device, whether the repeated portion is stored in a cache; creating, by the computing device and based on determining that the repeated portion is stored in the cache, the VM instance using the repeated portion stored in the cache; completing, by the computing device, the unique portion of the VM instance to create a completed VM instance; and deploying, by the computing device, the completed VM instance.

Abstract: Server resources in a data center are disaggregated into shared server resource pools. Servers are constructed dynamically, on-demand and based on workload requirements and a tenant's resiliency requirements (e.g., as specified in an SLA), by allocating from these resource pools. A disaggregated compute system of this type keeps track of resources that are available in the shared server resource pools, and it manages those resources based on that information and the health of the resources. As a workload is processed by the server entity and component resources fail, the server entity composition is changed, e.g. by allocating other resources to the server entity, or by transitioning to other server entities, to ensure that a resiliency requirement is maintained.

Abstract: During normal operation, at a first site, of a disaster recovery management unit, at least one customer workload machine, at least one management service machine, and metadata for the at least one management service machine are replicated to a remote disaster recovery site. After a disaster at the first site, a replicated version of the at least one customer workload machine and a replicated version of the at least one management service machine are brought up at the remote disaster recovery site. A replicated version of the metadata for the at least one management service machine is reconfigured by executing, on the replicated version of the at least one management service machine, a failover script, to obtain reconfigured replicated metadata for the replicated version of the at least one management service machine. When the first site comes back up, failback is carried out, essentially in the reverse order.

Abstract: Various embodiments for elastic resource provisioning in a disaggregated cloud computing environment, by a processor device, are provided. Respective members of pools of hardware resources within the disaggregated cloud computing environment are provisioned to a tenant according to an application-level service level agreement (SLA). Upon detecting a potential violation of the application-level SLA, additional respective members of the pools of hardware resources are provisioned on a component level to the tenant to avoid a violation of the SLA by one of a scale-up process and a scale-out process.
