Smoke testing your infrastructure with runbooks

Runbooks are essential tools for capturing valuable business knowledge in an automated and testable format, enabling level 1 support teams to efficiently diagnose issues and handle customer requests in enterprise environments. These environments often feature custom applications with complex infrastructure, where understanding the system's design and functionality can be challenging. The blog post provides an example runbook for smoke testing a typical microservice application in AWS, detailing steps for DNS verification, MySQL database testing, HTTP endpoint status checking, and load testing using tools like dig, curl, and hey. By implementing these smoke tests, support teams can quickly identify potential problems in the application's underlying services and infrastructure, ensuring they respond to support requests effectively.
