This part tends toward communicating the need to monitor performance for the reliability of the products. It also defines service-level indicators (SLIs), service level objectives (SLOs), service level agreements (SLA), plus purposes of integrated monitoring, logging, alerting, and debugging.
Learning Objectives:
- Describe SLIs, SLOs, and SLAs.
- Explain the importance of integrated monitoring, alerting, and debugging.
