Latest Patents

One of his latest patents is focused on virtual machine file management using file-level snapshots. This invention involves detecting a user request to access a virtual machine (VM) and searching a pre-defined list to determine if the user is authorized. If authorized, a file-level snapshot is generated before allowing modifications to the VM file. This snapshot includes user attributes that indicate the user's role, and it is added as the top layer of a stack. The VM file is then written in its entirety to the snapshot in response to user modifications. Based on the user attributes of each snapshot, a set of snapshots is selected, and the VM is modified by merging the VM files belonging to the selected snapshots.

Another notable patent by Da Long Wang involves controlling layers in container images to reduce redundant content between layers. This method manages an image by identifying a set of base files in image layers for a candidate file in a container layer. It creates a new image with a new top image layer using delta data identified for the candidate file. This innovative approach effectively reduces the size of images and the storage space required.
