Abstract: Techniques for fault-tolerant function placement across multiple computing placement locations are described. An application placement service obtains a latency-based placement of functions of an application and utilizes resource information associated with the placement locations to determine error rates for flows of the placement. For flows having an error rate falling outside of an allowable range, the application placement service can modify the placement to improve the error rate, e.g., by adding additional redundancy for functions in higher-error placement locations within those placement location tiers, and/or by adding additional redundancy for functions in higher-error placement locations within different placement location tiers.

Abstract: A resource optimization manager monitors resource metrics of a set of virtual machine instance types and determines a set of applications associated with the virtual machine instance types and associates the resource metrics to the set of applications. Thereafter, the resource optimization manager can generate clusters of applications that share one or more similar attributes and store resource optimizations for the clustered applications. The resource optimization manager can obtain a designation of a target application run on a virtual machine instance or otherwise obtain a definition of an application. The resource optimization manager can then associate the target application with one or more of the clustered applications based on a comparison of similarities between the clustered applications and the target applications.

Abstract: Generally described, aspects of the present disclosure relate to offload device virtual component checkpointing for fast recovery from virtual component software crashes by storing virtual component state configuration information and input/output (I/O) request identification information in non-volatile memory of a physical computing device physically separate from the offload device. In the event of a software crash of a virtual component, the crashed virtual component may be rebooted and reconfigured in accordance with the virtual component state configuration information and I/O request identification information stored in the non-volatile memory of the physical computing device.

Abstract: A provider network may implement resource management and billing for logical and physical availability zones. Consolidated billing techniques may be applied to the aggregate usage of multiple linked user accounts. A billing setting may indicate whether consolidated billing is performed according to resource consumption in logical availability zones or physical availability zones. Mappings to physical availability zones may be provided to linked user accounts so that computing resources may be consumed according to either logical or physical availability zones. Capacity reservations for computing resources for a particular physical availability zone may be made available to each of the linked user accounts for consumption.

Abstract: A multi-phase boot operation of a virtualization manager at a virtualization host is initiated at an offload card. In a first phase of the boot, a security key stored in a tamper-resistant location of the offload card is used. In a second phase, firmware programs are measured using a security module, and a first version of a virtualization coordinator is instantiated at the offload card. The first version of the virtualization coordinator obtains a different version of the virtualization coordinator and launches the different version at the offload card. Other components of the virtualization manager (such as various hypervisor components that do not run at the offload card) are launched by the different version of the virtualization controller.

Abstract: Techniques for dynamic resource movement in heterogeneous computing environments including provider substrate extensions are described. A dynamic resource movement service of a provider network monitor conditions of heterogeneous computing environments, including provider substrate extensions of the cloud provider network, to evaluate customer-provided movement policy conditions governing when to move customer application resources from these environments, where to move the resource to, and/or how to move the customer application resources. The customer-provided movement policy conditions may be based on a variety of factors, such as a latency between end-users of the customer application and the application itself.

Abstract: Techniques for configuring virtual machine instances are described herein. A virtual machine instance is instantiated and the virtual machine instance is monitored to receive notifications of configuration events associated with that virtual machine instance. Each configuration event, which specifies configuration changes to the virtual machine instance, includes a set of metadata associated with the configuration event. The metadata is extracted from the configuration event and the configuration changes are applied to the virtual machine instance. A new virtual machine image is then produced from the virtual machine instance and the extracted metadata is associated with the new virtual machine image.

Abstract: A wait optimizer circuit can be coupled to a processor to monitor an entry of a virtual CPU (vCPU) into a wait mode to acquire a ticket lock. The wait optimizer can introduce an amount of delay, while the vCPU is in the wait mode, with an assumption that the spinlock may be resolved before sending a wake up signal to the processor for rescheduling. The wait optimizer can also record a time stamp only for a first entry of the vCPU from a plurality of entries into the wait mode within a window of time. The time stamps for vCPUs contending for the same ticket lock can be used by a hypervisor executing on the processor for rescheduling the vCPUs.

Abstract: Remote computing resource service providers allow customers to execute virtual computer systems in a virtual environment on hardware provided by the computing resource service provider. The hardware may be distributed between various geographic locations connected by a network. The distributed environment may increase latency of various operations of the virtual computer systems executed by the customer. To reduce latency of various operations predictive modeling is used to predict the occurrence of various operations and initiate the operations before they may occur, thereby reducing the amount of latency perceived by the customer.
