Alluxio Overview

Alluxio is an open source software solution that connects analytics applications to heterogeneous data sources through a data orchestration layer that sits between compute and storage. It runs on commodity hardware, creating a shared data layer abstracting the files or objects in underlying persistent storage systems. Applications connect to Alluxio via a standard interface, accessing data from a single unified source. This white paper discusses the data center challenges Alluxio addresses, the benefits provided, and an overview of how it works.

Alluxio Architecture and Data Flow

Alluxio was created because we saw a need for innovation at the data layer rising from the growing complexity of connecting multiple compute frameworks to an ever-expanding mix of storage systems and formats. Our approach uses a memory-centric architecture that abstracts files and objects in underlying persistent storage systems and provides a shared data access … Continued
