Big Data Migration for Audio Recommendation Engine

Executive Summary

ANALYST: COI RESEARCH

The client migrated a massive 2,500-node on-premise Hadoop cluster to a managed cloud environment. This shift to managed services (Dataflow/BigQuery) allowed the engineering team to focus on recommendation algorithm logic rather than Hadoop cluster maintenance, accelerating the deployment of features like 'Discover Weekly'.

rate_review Analyst Verdict

"Validates the 'managed service' premium. While direct cloud compute costs may be higher than bare metal, the reduction in engineering maintenance hours and the speed of querying petabyte-scale data provide a superior Total Cost of Ownership (TCO) for data-driven firms."

warning The Challenge

Maintaining a 2,500-node on-premise Hadoop cluster required significant operational effort. As the user base grew to hundreds of millions, data processing jobs for personalization often failed or queued for hours, delaying the refresh of user recommendation playlists and analytics dashboards.

psychology The Solution

The company migrated its data processing pipeline to Google Cloud Platform, replacing HDFS with Google Cloud Storage and Hive/MapReduce with BigQuery and Dataflow. The architecture decoupled storage from compute, allowing queries to scale instantly without provisioning hardware.
