CrowdStrike has transitioned from using the Logrus logging library to Zerolog in its Go ecosystem to enhance performance and manageability for its extensive data processing needs. With Logrus becoming maintenance-only, CrowdStrike evaluated alternatives and chose Zerolog for its zero allocation and JSON logging capabilities, despite its limited format flexibility compared to Zap. The transition also involved creating a custom logging interface to avoid vendor lock-in and facilitate easier future migrations. This move is part of CrowdStrike's broader strategy to maintain high-performance logging solutions suitable for their scale, processing trillions of events weekly. Additionally, CrowdStrike had acquired Humio, a log management solutions provider, to offer scalable log aggregation across IT infrastructures, emphasizing the importance of log management in IT, DevOps, and SecOps.
