DeNA uses AI to shorten system failure root-cause investigation from two weeks to two days

Explanation

At DeNA, which operates games and services, system failures involving multiple interlinked mechanisms had previously taken up to two weeks to diagnose even with the entire team investigating. After building an AI operations platform that consolidates and analyzes logs, communication data, and processing records in one place, a single engineer became able to pinpoint the cause in just two days. The key was consolidating large volumes of data that had been stored separately into one location and organizing it so that AI could automatically find correlations. This case illustrates that what matters is not just how smart the AI itself is, but how the data fed to it is organized.
