Systems and methods for operating a cloud based computing system. The methods comprise: receiving, by a cloud server, a request for accessing Virtual Hard Disk ('VHD') data associated with a first location in the VHD of a Virtual Machine ('VM') hosted by a remote computing device; extracting, by the cloud server, at least a first address specifying the first location from the request; translating, by the cloud server, the first address into a second address specifying a second location in a cloud storage where the VHD data is stored; and communicating from the cloud server the second address to the remote computing device for facilitating access to the VHD data stored in the cloud storage.

Thin provisioning virtual desktop infrastructure virtual machines in cloud environments without thin clone support

Secure shared access to encrypted data in a data store is facilitated by using a data control server (DCS) to maintain a data storage reference table (DSRT) for shared data units present in a shared data pool hosted by least one data storage device, and accessible to a plurality of computing entities. The DSRT specifies for each shared data unit identifier information, location information for accessing the shared data unit in the shared data pool, and a hash value which has been computed for the shared data unit. The DCS selectively facilitates a decryption operation by providing hash values which serves as a basis for deriving a decryption key for decrypting shared data units which have been identified.

Secured encrypted shared cloud storage

A computing device for displaying images includes one or more processors to obtain graphical data that has been generated by one or more applications associated with a first virtual machine, and to map one or more virtual apertures or one or more actual buffers associated with the first virtual machine to a textual buffer associated with a second virtual machine, and process the graphical data based on the mapping. The virtual apertures are in a virtual memory space and the actual buffers being in a physical memory space. The graphical data includes rendered composite graphical data representing a desktop and one or more application windows. The one or more processors allocate physical memory space in the textual buffer associated with the second virtual machine to support the mapping. A display device displays images using the processed graphical data.

Displaying graphics for local virtual machine by allocating and mapping textual buffer

A computing device is provided for displaying images that are two dimensional (2D) or three dimensional (3D). The computing device includes one or more processors configured to obtain graphical data that has been generated by one or more applications associated with a first virtual machine and map one or more virtual apertures or one or more actual buffers associated with the first virtual machine to a textual buffer associated with a second virtual machine. The virtual apertures are in a virtual memory space and the actual buffers are in a physical memory space. The one or more processors are also configured to process the graphical data based on the mapping. The computing device also includes a display device configured to display the 2D or 3D images using the processed graphical data.
