Abstract:
A network-based virtual computing resource provider may offer virtual compute instances that implement rolling resource credits for scheduling virtual computing resources. Work requests for a virtual compute instance may be received at a virtualization manager. A resource credit balance may be determined for the virtual compute instance. The resource credit balance may accumulate resource credits in rolling fashion, carrying over unused credits from previous time periods. Resource credits may then be applied when generating scheduling instructions to provide to a physical resource to perform the work requests, such as a physical CPU in order to increase the utilization of the resource according to the number of credits applied. Applied resource credits may then be deducted from the credit balance.
Abstract:
A task definition is received. The task definition indicates at least a location from which one or more software image can be obtained and information usable to determine an amount of resources to allocate to one or more software containers for the one or more software image. A set of virtual machine instances in which to launch the one or more software containers is determined, the one or more software image is obtained from the location included in the task definition and is launched as the one or more of software containers within the set of virtual machine instances.
Abstract:
A system and method for software deployment, where the system and method include, at a deployment service, obtaining a software package and determining that a client device is ready to receive at least a portion of the software package. If the client device is ready, providing at least the portion of the software package to the client device, launching at least the provided portion of the software package as set of instructions executing in a test container, and performing a set of tests on the executing set of instructions in the test container. Based at least in part on results of performing the set of tests, determining whether to cause at least the provided portion of the software package to execute in an active container on the client device.
Abstract:
A provider network may implement resource credit pools to replenish resource credit balances for virtual compute instances. A resource credit pool may be maintained that makes resource credits available to virtual compute instances authorized to obtain resource credits from the resource credit pool. Resource credits from the resource credit pool may be applicable to increase utilization of physical computer resource for a virtual compute instance. In response to a resource credit request for an authorized virtual compute instance, a number of resource credits to add to an individual resource credit balance for the authorized virtual compute instance may be determined. A response may be sent indicating the number of resource credits to add to the individual resource credit balance and the resource credit pool may be updated to remove the number of resource credits from the resource credit pool.
Abstract:
A virtualized system that is capable of executing a computation that has been identified as a repeatable computation and recording various representations of the state of the computing environment throughout the execution of the repeatable computation, where the state of the computing environment can be cryptographically signed and/or verified using a trusted platform module (TPM), or other cryptographic module. For example, a TPM embedded in the host computing device may generate a hash measurement that captures the state of the repeatable computation at the time of the computation. This measurement can be digitally signed using one or more cryptographic keys of the TPM and recorded for future use. The recorded state can subsequently be used to repeat the computation and/or determine whether the computation was repeated successfully according to certain defined criteria.
