Abstract: Example implementations relate to determining and implementing a feasible resource optimization plan for public cloud consumption. Telemetry data over a period of time is obtained for a current deployment of virtual infrastructure resources within a current data center of a cloud provider that supports an existing service and an application deployed on the virtual infrastructure resources. Information regarding a set of constraints to be imposed on a resource optimization plan is obtained. Indicators of resource consumption relating to the currently deployed virtual infrastructure resources during the period of time are identified by applying a deep learning algorithm to the telemetry data. A resource optimization plan is determined that is feasible within the set of constraints based on a costing model associated with resources of an alternative data center of the cloud provider, the indicators of resource consumption and costs associated with the current deployment.

Abstract: An example recommendation device can include a memory resource storing instructions executable by a processing resource to: determine dependencies of a hardware topology, determine properties of an upgrade to be performed on the hardware topology, compare the properties of the upgrade to the determined dependencies of the hardware topology to identify potential events, and generate a recommendation for deploying the upgrade on the hardware topology based on the comparison.

Abstract: Encoding of domain logic rules in an analog content addressable memory (aCAM) is disclosed. By encoding domain logic in an aCAM, rapid and flexible search capabilities are enabled, including the capability to search ranges of analog values, fuzzy match capabilities, and optimized parameter search capabilities. This is achieved with low latency by using only a small number of clock cycles at low power. A domain logic ruleset may be represented using various data structures such as decision trees, directed graphs, or the like. These representations can be converted to a table of values, where each table column can be directly mapped to a corresponding row of the aCAM.

Abstract: Systems and methods are configured to provide a first problem to be solved to a network of memristors. A second problem to be solved can be gradually provided to the network of memristors. Controlled noise can be applied to the network of memristors for at least a portion of time during which the second problem is “gradually” provided to the network of memristors. A solution to the second problem can be determined.

Abstract: A system and method are provided for facilitating efficient management of data structures stored in remote memory. During operation, the system receives a request to allocate memory for a first part in a data structure stored in a remote memory associated with a compute node in a network. The system pre-allocates a buffer in the remote memory for a plurality of parts in the data structure and stores a first local descriptor associated with the buffer in a local worker table stored in a volatile memory of the compute node. The first local descriptor facilitates servicing future access requests to the first and other parts in the data structure. The system stores a first global descriptor for the buffer in a shared global table stored in the remote memory and generates a first reference corresponding to the first part, thereby facilitating faster traversals of the data structure.

Abstract: A computer implemented method may include: storing key-value pairs in an index in persistent storage, where indirect nodes of the index include pointers, where each pointer identifies an index portion and includes a generation identifier for the identified index portion, where the index comprises a plurality of snapshots associated with a plurality of generations; receiving a request to read data of a particular snapshot of the index, wherein the particular snapshot is associated with a particular generation of the plurality of generations; in response to the request, performing a traversal starting from a particular root node associated with the particular generation; and providing the requested data based on the traversal.

Abstract: While scheduled checkpoints are being taken of a cluster of active compute nodes distributively executing an application in parallel, a likelihood of failure of the active compute nodes is periodically and independently predicted. Responsive to the likelihood of failure of a given active compute node exceeding a threshold, the given active compute node is proactively migrated to a spare compute node of the cluster at a next scheduled checkpoint. Another spare compute node of the cluster can perform prediction and migration. Prediction can be based on both hardware events and software events regarding the active compute nodes.

Abstract: Examples described herein relate to a method and a system, for example, a restore management system for providing secure restore of computing system. In some examples, the restore management system may determine that the computing system is restored. Further, the restore management system may isolate the computing system by restricting access to the computing system for any data traffic other than data traffic associated with a security fix to be applied to the computing system. Furthermore, the restore management system may determine that the security fix has been successfully applied to the computing system and, in response to determining that the security fix has been successfully applied, the restore management system may remove the computing system from isolation.

Abstract: Examples disclosed herein relate to a method comprising receiving a data packet originating from a first device and intended for a second device, wherein the first device and the first access device belong to a first branch of a Wide Area Network (WAN) using a MPLS overlay and the second device belongs to a second branch of the WAN. The method includes encapsulating the data packet in VXLAN including a VXLAN label identifying a role type and transmitting the data packet to a first core device. The method includes determining an MPLS label corresponding to the role type and transmitting the data packet over the MPLS overlay to a second core device belonging to the second branch of the WAN. The method includes translating the MPLS label into the VXLAN label and transmitting the data packet including the VXLAN label to a second access device for an enforcement action.
