摘要： Embodiments of the present disclosure are directed to, among other things, validating the integrity of received and/or stored data payloads. In some examples, a storage service may perform a first partitioning of a data object into first partitions based at least in part on a first operation. The storage service may also verify the data object, by utilizing a verification algorithm, to generate a first verification value. In some cases, the storage service may additionally perform a second partitioning of the data object into second partitions based at least in part on a second operation. The second partitions may be different from the first partitions. Additionally, the archival data storage service may verify the data object using the verification algorithm to generate a second verification value. Further, the storage service may determine whether the second verification value equals the first verification value.

摘要： Techniques for implementing a data management scheme for optimizing data storage are described herein. A deletion quantity or other metric relating to deletions of data within a first storage zone are tracked. Upon detection that the tracked deletion metric meets certain criteria, the data within the first storage zone are moved to a second storage zone. A verification of the data to be moved is also performed, and if such verification indicates that at least a portion of the data is corrupted, routines repairing and/or restoring at least the corrupted portion are initiated.

摘要： Techniques for optimizing data storage are disclosed herein. In particular, methods and systems for implementing redundancy encoding schemes with data storage systems are described. The redundancy encoding schemes may be scheduled according to system and data characteristics. The schemes may span multiple tiers or layers of a storage system. The schemes may be generated, for example, in accordance with a transaction rate requirement, a data durability requirement or in the context of the age of the stored data. The schemes may be designed to rectify entropy-related effects upon data storage. The schemes may include one or more erasure codes or erasure coding schemes. Additionally, methods and systems for improving and/or accounting for failure correlation of various components of the storage system, including that of storage devices such as hard disk drives, are described.

摘要： In this disclosure, a resource scheduler is described that allows virtual machine instances to earn resource credits during the low activity levels. Virtual machine instances that spend a predominant amount of time operating at low activity levels are able to quickly gain resource credits. Once these virtual machine instances acquire enough resource credits to surpass a threshold level, the resource scheduler can assign a high priority level to the virtual machine instances that provide them with priority access to CPU resources. The next time that the virtual machine instances enter a high activity level, they have a high priority level that allows them to preempt other, lower priority virtual machine instances. Thus, these virtual machine instances are able to process operations and/or respond to user requests with low latency.
摘要翻译： 在本公开中，描述了允许虚拟机实例在低活动级别期间获得资源信用的资源调度器。 花费大量时间运作在低活动水平的虚拟机实例能够快速获得资源信用。 一旦这些虚拟机实例获得足够的资源信用以超过阈值级别，资源调度器就可以为虚拟机实例分配高优先权级别，从而为其提供对CPU资源的优先访问。 虚拟机实例下一次进入高活动级别时，它们具有高优先级，允许它们抢占其他优先级较低的虚拟机实例。 因此，这些虚拟机实例能够以低延迟处理操作和/或响应用户请求。

摘要： Technologies are described herein for ensuring data in long-term storage will be accessible at a future date. Upon storing the data in long-term storage, a well-defined instance of data processing resources is created on a host computing platform for the installation and testing of a related application that is capable of accessing the stored data. Once testing of the related application is complete, a machine image is generated from the instance and stored with the data in the long-term storage. If access to the data stored in the long-term storage is required at a future date, the data and associated machine image may be retrieved, and a compatible instance of data processing resources created in which the machine image may be restored. The data in the long-term storage may then be accessed by the related applications executing in the newly created instance.
