Oracle Cloud Infrastructure Architect Professional Workshop — Lesson 4: High Availability, Disaster Recovery, Observability, Cost, and Operations

Learning Objectives

• Explain the architecture, workflow, or business purpose behind failure domains, redundancy, backups, cross-region recovery, and RTO or RPO.
• Apply full-stack disaster recovery patterns, drills, dependencies, and runbooks and logging, monitoring, APM, alarms, events, automation, and SRE practices in a controlled scenario.
• Validate outcomes and troubleshoot risks involving cost models, capacity, performance tests, architecture review, and improvement roadmap.

Detailed Topics

• failure domains, redundancy, backups, cross-region recovery, and RTO or RPO
• full-stack disaster recovery patterns, drills, dependencies, and runbooks
• logging, monitoring, APM, alarms, events, automation, and SRE practices
• cost models, capacity, performance tests, architecture review, and improvement roadmap

Instructor Demonstration

Demonstrate failure domains, redundancy, backups, cross-region recovery, and RTO or RPO within a multi-region customer platform migrating to OCI with strict isolation, recovery, performance, compliance, and cost requirements, then capture the exact configuration, command, transaction, report, model, query, code, or process evidence that proves the result for lesson 4.

Hands-On Exercise

Implement a controlled exercise covering full-stack disaster recovery patterns, drills, dependencies, and runbooks and logging, monitoring, APM, alarms, events, automation, and SRE practices, then introduce and resolve an exception involving cost models, capacity, performance tests, architecture review, and improvement roadmap while preserving before-and-after evidence.

1. Confirm the environment, identities, inputs, dependencies, risks, and expected outcome.
2. Complete the course-specific configuration, development, analysis, or process workflow.
3. Capture settings, commands, data, outputs, logs, reports, screenshots, calculations, or test results.
4. Compare the observed result with acceptance criteria and document corrective action.

Scenario Analysis

• Identify the technical or business decision that must be made.
• Compare valid approaches and their security, performance, reliability, cost, compliance, and support trade-offs.
• Define rollback, recovery, ownership, communication, and evidence requirements.

Troubleshooting Guidance

Diagnose issues across failure domains, redundancy, backups, cross-region recovery, and RTO or RPO, full-stack disaster recovery patterns, drills, dependencies, and runbooks, logging, monitoring, APM, alarms, events, automation, and SRE practices, cost models, capacity, performance tests, architecture review, and improvement roadmap without making an unverified production change. Separate symptoms from causes, gather evidence, test the smallest reversible correction, rerun validation, and record preventive action.

Validation Checklist

• The requirement, scope, inputs, dependencies, and expected result are documented.
• The result is reproducible and supported by course-specific evidence.
• Normal, boundary, failure, security, performance, and operational conditions are reviewed.
• Exceptions, rollback, ownership, and the next improvement priority are recorded.

Lesson Outcome

Learners can apply High Availability, Disaster Recovery, Observability, Cost, and Operations in a realistic Oracle Cloud Infrastructure Architect Professional Workshop scenario and validate the result with documented evidence.
