The present disclosure relates to a framework that provides execution of serverless functions in a cloud environment based on occurrence of events/notifications from services in an entirely different cloud environment. A target agent obtains a notification from a source agent, where the target agent is deployed in a target cloud environment and the source agent is deployed in a source cloud environment that is different than the target cloud environment. The target agent determines a function that is to be invoked based on the notification. Upon successfully verifying whether the target agent is permitted to invoke the function that is deployed in a target customer tenancy of the target cloud environment, the target agent invokes the function in the target customer tenancy of the target cloud environment.

Remote cloud function invocation service

Systems, methods, and other embodiments associated with performing maintenance of a hardware node and relocating (live migrating) virtual machine (VM) instances in a multi-tenant, hyper scale, public Cloud service are described. In one embodiment, the method includes finding a suitable hardware node for hosting one or more VM instances from a hardware node selected for maintenance, preparing it for hosting VMs, and moving (live migrating) all virtual machines from the hardware node to the hosting hardware node.

System and method for relocating customer virtual machine instances in a multi-tenant cloud service

The techniques described herein limit client utilization of a parallel-access storage device. Specifically, client utilization of a particular storage device is estimated using I/O cost metrics to estimate the costs of I/O requests from the client to the particular storage device. The I/O cost metrics are determined based on calibration-based system performance data, which represents a system-wide measure of storage device performance for a system in which the particular storage device resides. The calibration-based system performance data includes one or both of composite throughput data and composite IOPS data for multiple parallel-access devices in the system. The cost estimates for I/O requests issued from a client to a parallel-access device are tracked in a total cost estimate for the client. Client utilization of the storage device, as tracked by the total cost estimate for the client, is limited to a percentage of the total estimated bandwidth of the storage device.

Consistently enforcing I/O resource constraints for workloads on parallel-access storage devices

Disclosed is an improved approach for managing access to resources by workloads in a computing system. A much more accurate and useful technique is provided for determining disk utilization, and for using the calculated disk utilization to enforce workload constraints and limits. The technique may be used by any application that is attempting to share storage between multiple workloads can use the present solution, as well as any operating system and workload manager that need to manage workloads and resources.

Method and system for implementing workload management by monitoring disk utilizations

Techniques are provided for managing, within a storage system, the sequence in which I/O requests are processed by the storage system based, at least in part, on one or more logical characteristics of the I/O requests. The logical characteristics may include, for example, the identity of the user for whom the I/O request was submitted, the service that submitted the I/O request, the database targeted by the I/O request, an indication of a consumer group to which the I/O request maps, the reason why the I/O request was issued, a priority category of the I/O request, etc. Techniques are also provided for automatically establishing a scheduling policy within a storage system, and for dynamically changing the scheduling policy in response to changes in workload.

Storage-side storage request management

Techniques are provided for managing, within a storage system, the sequence in which I/O requests are processed by the storage system based, at least in part, on a one or more logical characteristics of the I/O requests. The logical characteristics may include, for example, the identity of the user for whom the I/O request was submitted, the service that submitted the I/O request, the database targeted by the I/O request, an indication of a consumer group to which the I/O request maps, the reason why the I/O request was issued, a priority category of the I/O request, etc. Techniques are also provided for automatically establishing a scheduling policy within a storage system, and for dynamically changing the scheduling policy in response to changes in workload.
