Cloud Logging

Cloud Logging is the process of collecting, storing, and analyzing log data generated by applications and infrastructure running in the cloud. It acts like a black box flight recorder for your digital systems, capturing every event, error, and transaction for later review.

Cloud Logging

1. How It Works

Cloud logging typically follows a three-step cycle:

  • Ingestion: Logs are automatically collected from virtual machines, containers, and serverless functions.
  • Storage: Logs are stored in a highly durable database where they can be kept for days, months, or years.
  • Analysis: Engineers use dashboards and search tools to filter logs and identify the root cause of issues.

2. Why Use Cloud Logging?
