Abstract
Described herein is technology for, among other things root image caching and indexing for block-level distributed application management. The technology involves storing blocks of a root image on a first storage unit and storing blocks of leaf images on respective second storage units. The leaf images include additional data blocks not previously contained in the root image and changes made by respective compute nodes to the blocks of the root image. The technology includes caching blocks of the root image that have been accessed by at least one compute node. The technology also includes receiving indexing results pertaining to the root image from one compute node and providing the results for other compute nodes.
