Comcast Hybrid Cloud Data Platform Case Study: Seamless and Secure Data Access with Alluxio
Comcast’s hybrid‑cloud data platform, built on Trino and Amazon S3, faced challenges such as fragmented data access, costly data copies, and latency, leading the DX team to adopt Alluxio as a unified, cache‑enabled, secure middle‑layer that bridges storage and compute.
Comcast is the world’s second‑largest broadcast and cable television company and the largest residential internet service provider in the United States.
The company built a hybrid‑cloud data platform that uses Trino as the query engine and Amazon S3 for storage. While this architecture offers a flexible “build vs. buy” cost model, it also introduced several challenges: lack of a unified data‑access protocol, heavy data‑copy overhead, high latency for remote access, and rising S3 traffic costs.
To address these issues, Comcast’s DX (Data Experience) team selected Alluxio as a middle‑layer that sits between storage and compute engines, providing a common data‑access layer for applications moving data from AWS to on‑premises environments.
Solution: Seamless, Secure Hybrid‑Cloud Data Access
1. Reduce data duplication in the hybrid cloud through caching.
2. Offer a flexible API that connects compute and storage.
3. Provide a universal security model that integrates with Apache Ranger.
