DO274: Introduction to Event-Driven Ansible — Lesson 1: Event-Driven Automation Concepts, Architecture, Sources, and Event Normalization

Learning Objectives

• Interpret the architecture, dependencies, and expected behavior of event-driven automation, architecture, and event sources.
• Apply event normalization and use cases while preserving reviewable technical evidence.
• Recognize and correct the risk where a hidden prerequisite causes the first configuration step to produce an incomplete result.

Detailed Topics

• event-driven automation: apply the concept to an operations team automating responses to monitoring alerts and infrastructure events, record the relevant settings or decisions, and explain the operational consequence.
• architecture: apply the concept to an operations team automating responses to monitoring alerts and infrastructure events, record the relevant settings or decisions, and explain the operational consequence.
• event sources: apply the concept to an operations team automating responses to monitoring alerts and infrastructure events, record the relevant settings or decisions, and explain the operational consequence.
• event normalization: apply the concept to an operations team automating responses to monitoring alerts and infrastructure events, record the relevant settings or decisions, and explain the operational consequence.
• use cases: apply the concept to an operations team automating responses to monitoring alerts and infrastructure events, record the relevant settings or decisions, and explain the operational consequence.

Instructor Demonstration

The instructor demonstrates event-driven automation concepts, architecture, sources, and event normalization by tracing the relevant architecture, commands, configuration, messages, and evidence. The walkthrough highlights how a hidden prerequisite causes the first configuration step to produce an incomplete result and shows how to isolate the cause without masking dependent issues.

Hands-On Exercise

Build a baseline and capture the initial state for Event-Driven Automation Concepts, Architecture, Sources, and Event Normalization. Add verified outcomes to the event source integration, tested Ansible Rulebooks, response workflow evidence, and operations guide.

1. Confirm the scope, versions, access, dependencies, and success criteria.
2. Perform the workflow while recording commands, settings, output, and platform events.
3. Test one expected case and one controlled exception specific to this lesson.
4. Retest the correction and document ownership, rollback, and follow-up actions.

Scenario Analysis

• Identify which dependency most strongly influences event-driven automation in the stated scenario.
• Compare two approaches for event normalization and explain the security, reliability, and support trade-offs.
• Decide what evidence must be retained in the event source integration, tested Ansible Rulebooks, response workflow evidence, and operations guide before operational acceptance.

Troubleshooting Guidance

Begin with the first observable difference from the expected result. Check architecture, access, dependencies, and starting conditions separately, then correlate logs, events, commands, and configuration history. Do not accept the initial assumption that a hidden prerequisite causes the first configuration step to produce an incomplete result; confirm the cause with a reproducible retest.

Validation Checklist

• The required architecture, access, dependencies, and starting conditions were checked and recorded.
• The normal path and a course-specific exception were tested.
• The event source integration, tested Ansible Rulebooks, response workflow evidence, and operations guide links conclusions to commands, configuration, logs, or other objective evidence.
• Corrective actions, rollback steps, ownership, and handover notes are complete.

Lesson Outcome

Learners can apply Event-Driven Automation Concepts, Architecture, Sources, and Event Normalization, explain the observed Red Hat platform behavior, and support the result with a reviewable event source integration, tested Ansible Rulebooks, response workflow evidence, and operations guide.
