Embodiments present a virtual disk image to applications such as virtual machines (VMs) executing on a computing device. The virtual disk image corresponds to one or more subparts of binary large objects (blobs) of data stored by a cloud service, and is implemented in a log structured format. Grains of the virtual disk image are cached by the computing device. The computing device caches only a subset of the grains and performs write operations without blocking the applications to reduce storage latency perceived by the applications. Some embodiments enable the applications that lack enterprise class storage to benefit from enterprise class cloud storage services.

Transparent virtualization of cloud storage

A method of pairing an unregistered device with a virtual identity may include, at a first repository: receiving a request from the unregistered device, sending a pairing code and an identifier to the unregistered device, receiving the pairing code from a registered device, and sending the identifier to the registered device. The method may also include, at a second repository, receiving the pairing code and secret information from the registered device, receiving the pairing code in a transmission associated with the unregistered device, associating the unregistered device with the virtual identity using the pairing code, and sending the secret information to the unregistered device.

Methods and systems for pairing devices

A technique controls access to a file. The technique involves creating a file encryption key based on (i) a user input parameter (e.g., a user password) from a user of the client device and (ii) an automatically generated salt parameter (e.g., a random number). The technique further involves encrypting the file using the file encryption key to form an encrypted copy of the file, and providing the salt parameter to an external storage system to externally store the salt parameter. Access to data within the encrypted copy of the file requires the salt parameter provided to the external storage system.

Controlling access to data within encrypted copies of files using salt parameters

Storing data includes encoding the data using an erasure encoding to provide encoded data, separating the encoded data into a number of components, and providing each of the components to separate data sites. The data may be encoded using a Reed/Solomon encoding. The data may be encoded using a 3-1 Reed/Solomon encoding and the encoded data may be separated into four components that are provided to four separate sites. The data may be encoded by a site that receives the data prior to encoding. The data may be encoded by a client that provides the data to a plurality of sites coupled thereto. Storing data may also include each of the separate data sites providing an additional encoding for the components. The data and the components may be encoded using a Reed/Solomon encoding.
