Abstract: Methods and systems are described for provisioning cloud-based database systems and performing decoupled maintenance. For example, conventional systems may rely on database management systems to provision and modify databases hosted by a service provider. However, for entities operating complex database systems with the need for highly customized cloud infrastructure, database management systems fail to provide the granular customization and the control necessary to create and service these systems. In contrast, the described solutions provide an improvement over conventional database management system architecture by providing direct communication between an entity and its cloud-based database systems via command line prompts or API calls, decoupling database system maintenance from database system provisioning process to increase the speed and granular customization of the database system.

Abstract: A resource matching technique between a primary site and one or more secondary sites accommodates a configuration update of a virtual machine (VM) in a disaster recovery (DR) environment. The resource matching technique determines whether a proposed resource configuration update or change to a primary VM running at the primary site is permissible on a secondary VM configured for failover operation at a secondary site in the event of failure to the primary VM. The technique continuously monitors the availability of resources at each secondary site and enables negotiation between the primary and secondary sites of the proposed configuration change based on corresponding indications resource availability. The resources may include generic resources (e.g., memory, storage capacity and CPU processing capacity) and specialized resources (e.g., GPU types and/or models).

Abstract: A fault recovery system including a fault controller is disclosed. The fault controller is coupled between a processor and an interconnect, and configured to receive a time-out signal that is indicative of a failure of the processor to execute a transaction after a fault is detected in the processor. The failure in the execution of the transaction results in queuing of the interconnect. Based on the time-out signal, the fault controller is further configured to generate and transmit a control signal to the processor to disconnect the processor from the interconnect. Further, the fault controller is configured to execute the transaction, and in turn, dequeue the interconnect. When the transaction is successfully executed, the fault controller is further configured to generate a status signal to reset the processor, thereby managing a fault recovery of the processor.

Abstract: An example computing device includes a controller to control operation of a firmware subsystem of the computing device. The controller is separate from a main processor of the computing device. A memory stores subsystem data that is useable by the controller. The subsystem data includes recovery information executable by the controller to initiate recovery of the subsystem. The computing device further includes recovery coordination instructions. The recovery coordination instructions determine integrity of the recovery information as stored on the memory and. In response to determining that the recovery information lacks integrity, the recovery coordination instructions initiate recovery of the firmware subsystem using a backup of the recovery information and perform recovery of the firmware subsystem using an update to the firmware subsystem.

If a failure occurs in an active IO domain, the communication functions performed by the failing active IO domain are transferred to the other IO domain.

Abstract: There are provided systems and methods for a fallback artificial intelligence (AI) system for redundancy during system failover. A service provider may provide AI systems for automated decision-making, such as for risk analysis, marketing, and the like. An AI system may operate in a production computing environment in order to provide AI decision-making based on input data, for example, by providing an output decision.

This may utilize a deep neural network and a continual learning trainer. Thereafter, when a failover condition is detected for the production AI system, the service provider may switch from the production AI system to the fallback AI system, which may provide decision-making operations during failure of within the production computing environment.

Abstract: To locate an intermittent fault in a communication structure of an aircraft comprising pieces of equipment that are interconnected by cabling forming a plurality of communication media that are shared, an analyzer retrieves an error report relating to transmission errors observed on each of said communication media, performs a count of the transmission errors, per type of error and per communication chain, computes a median of the counts for communication chains comprising the same pair of wired pieces of equipment, and when, for a communication chain, the count exceeds a threshold equal to the median plus a predefined margin, generates an alarm indicating detection of an intermittent fault in association with the communication chain that led the threshold to be exceeded. Thus, intermittent faults are easily located and repaired.
