COMMUNITY VIRTUAL EVENT
Learn how Alluxio, a virtual data lake, could help simplify each stage of the ML life cycle: data collection, data cleansing, model training, model validation, and model inference/deployment stages.
Check out the talks from our virtual community event, Alluxio Day XII, featuring presenters from Websec, Shopee, and Alluxio.
Alluxio 2.8 expands data access & security for data-driven applications in heterogeneous environments – Enhanced S3 API, data encryption & policy-driven data management, and more.

Alluxio enables compute

Data locality
Bring your data close to compute.
Make your data local to compute workloads for Spark caching, Presto caching, Hive caching and more.

Data Accessibility
Make your data accessible.
No matter if it sits on-prem or in the cloud, HDFS or S3, make your files and objects accessible in many different ways.

Data On-Demand
Make your data as elastic as compute.
Effortlessly orchestrate your data for compute in any cloud, even if data is spread across multiple clouds.
“zero-copy” burst user spotlight: walmart

Why Walmart chose Alluxio’s “Zero-Copy” burst solution:
- No requirement to persist data into the cloud
- Improved query performance and no network hops on recurrent queries
- Lower costs without the need for creating data copies
See more on how Alluxio powers Walmart’s “zero-copy” burst solution in their presentation >
Featured Use Cases and Deployments
Managing data copies/app changes when bursting compute to cloud?
Zero-copy hybrid bursting with no app changes to intelligently make remote data accessible in the public cloud.
Expanding compute capacity across geo-distributed data centers?

Zero-copy bursting across data centers for Presto, Spark, and Hive with no app changes on data stored in HDFS.
Interact with Alluxio in any stack
Pick a compute. Pick a storage. Alluxio just works.
