Quick Answer
Centralized logging aggregates logs from all services into one place. Each service writes structured JSON logs. A log shipper (Fluentd, Fluent Bit) collects and forwards to a central store (Elasticsearch, Loki, CloudWatch). You can then search, filter, and correlate across all services. Without centralization, debugging means SSHing to each server individually.
