ABSTRACT:
A sparsely populated, streaming virtual disk may be used with a virtual application to enable fast launching of a virtual application from a network server. The virtual disk may be configured and populated in blocks, enabling those blocks that are used at a particular time to be downloaded and stored in the virtual disk. As other blocks are requested by the virtual application, those blocks may be fetched from the network server. Each block may be validated using a hash tree or some other function so that the recipient may verify authenticity and completeness. In some embodiments, a virtual application may be configured and deployed as a single file, enabling simple version control among other things.
