TL112 – Red Hat Transformational Learning: Introduction to Pragmatic Site Reliability Engineering — Lesson 4: SRE Adoption, Team Interfaces, Metrics, Governance, and Improvement Roadmap

Learning Objectives

• Operate, diagnose, document, recover, and improve adoption planning, team interfaces, and reliability metrics.
• Apply governance and improvement roadmap while preserving reviewable technical evidence.
• Recognize and correct the condition where the technical result is restored but monitoring, rollback, evidence, ownership, or handover remains incomplete.

Detailed Topics

• adoption planning: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• team interfaces: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• reliability metrics: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• governance: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• improvement roadmap: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.

Instructor Demonstration

The instructor demonstrates sre adoption, team interfaces, metrics, governance, and improvement roadmap by tracing architecture, commands, configuration, system messages, and evidence. The walkthrough tests how the technical result is restored but monitoring, rollback, evidence, ownership, or handover remains incomplete and explains how to isolate the cause without masking related issues.

Hands-On Exercise

Conduct an operational acceptance review for SRE Adoption, Team Interfaces, Metrics, Governance, and Improvement Roadmap and add the verified result to the service reliability charter, SLI and SLO register, error-budget policy, and improvement roadmap.

1. Confirm scope, versions, access, dependencies, assumptions, and acceptance criteria.
2. Perform the workflow while recording commands, configuration, output, events, and decisions.
3. Test the normal path and one course-specific exception or boundary condition.
4. Retest the correction and document rollback, ownership, and follow-up actions.

Scenario Analysis

• Identify which dependency most strongly influences adoption planning in the stated scenario.
• Compare two approaches for governance and explain the security, reliability, performance, and support trade-offs.
• Decide what evidence must be retained in the service reliability charter, SLI and SLO register, error-budget policy, and improvement roadmap before operational acceptance.

Troubleshooting Guidance

Begin with the first observable difference from the expected result. Check monitoring, troubleshooting, rollback, ownership, evidence, and handover separately, then correlate logs, events, commands, metrics, and configuration history. Treat the assumption that the technical result is restored but monitoring, rollback, evidence, ownership, or handover remains incomplete as a hypothesis until a reproducible retest confirms the cause.

Validation Checklist

• The required monitoring, troubleshooting, rollback, ownership, evidence, and handover were checked and recorded.
• The normal path and a course-specific exception were tested.
• The service reliability charter, SLI and SLO register, error-budget policy, and improvement roadmap links conclusions to commands, configuration, logs, metrics, or other objective evidence.
• Corrective actions, rollback, ownership, and handover notes are complete.

Lesson Outcome

Learners can apply SRE Adoption, Team Interfaces, Metrics, Governance, and Improvement Roadmap, explain the observed platform behavior, and support the result with a reviewable service reliability charter, SLI and SLO register, error-budget policy, and improvement roadmap.
