Abstract:
Cloud computing platforms having computer-readable media that perform methods to manage virtual hard drives as blobs are provided. The cloud computing platform includes fabric computers and blob stores. The fabric computers execute virtual machines that implement one or more applications that access virtual hard drives. The data in the virtual hard drives is accessed, via a blob interface, from blobs in the blob stores. The blob stores interface with a driver that translates some application input/output (I/O) requests destined to the virtual hard drives to blob commands when accessing data in the virtual hard drives.
Abstract:
Partition management for a scalable, structured storage system is provided. The storage system provides storage represented by one or more tables, each of which includes rows that represent data entities. A table is partitioned into a number of partitions, each partition including a contiguous range of rows. The partitions are served by table servers and managed by a table master. Load distribution information for the table servers and partitions is tracked, and the table master determines to split and/or merge partitions based on the load distribution information.
Abstract:
Atomic multiple modifications of streams is provided. Streams are selected for the application of an atomic multiple modification. A lock is acquired on the meta-data associated with the streams. Each stream is de-coupled from its name. Multiple modifications are applied to the selected streams. After performing the modifications, names are coupled to the streams. The lock on the meta-data associated with each stream is released.

Abstract:
Cloud computing platforms having computer-readable media that perform methods for facilitating communications with storage. A request having a first-interface format to access storage is intercepted. The first interface format of the request supports access to a virtual hard drive (VHD). The request is translated to a blob request having a blob interface format. The blob interface format of the blob request supports access to a plurality of blobs of data in a blob store. The blob request is communicated to a blob interface such that the blob request is executed in managing the plurality of blobs.

Abstract:
Se proporciona manejo de división para un sistema de almacenamiento escalable, estructurado. El sistema de almacenamiento proporciona almacenamiento representado por una o más tablas, cada una de las cuales incluye filas que representan entidades de datos. Una tabla se divide en un número divisiones, cada división incluyendo una variedad de filas contiguas. Las divisiones son servidas por servidores de tabla y se manejan por un maestro de tabla. La información de distribución de carga para los servidores de tabla y divisiones se rastrea, y el maestro de tabla determina dividir y/o fusionar divisiones basándose en la información de distribución de carga.
