Oracle Cloud Infrastructure Developer Professional: Hands-on Workshop — Lesson 4: Security, Observability, Resilience, Testing, and Developer Operations

Learning Objectives

• Explain the purpose and operating context of Vault keys, secrets, certificates, WAF awareness, and secure configuration.
• Apply logs, metrics, traces, APM, alarms, and correlation identifiers and timeouts, retries, circuit breakers, concurrency, and fault isolation in a controlled environment.
• Validate outcomes and troubleshoot risks involving automated tests, deployment evidence, cost review, and application runbook.

Detailed Topics

• Vault keys, secrets, certificates, WAF awareness, and secure configuration
• logs, metrics, traces, APM, alarms, and correlation identifiers
• timeouts, retries, circuit breakers, concurrency, and fault isolation
• automated tests, deployment evidence, cost review, and application runbook

Instructor Demonstration

Demonstrate Vault keys, secrets, certificates, WAF awareness, and secure configuration for an event-driven order application implemented and deployed through OCI developer services; capture the exact configuration, code, command, transaction, query, dashboard, model, schedule, or report evidence that proves the expected result.

Hands-On Exercise

Complete a controlled Oracle Cloud Infrastructure Developer Professional: Hands-on Workshop exercise covering logs, metrics, traces, APM, alarms, and correlation identifiers and timeouts, retries, circuit breakers, concurrency, and fault isolation; introduce an exception involving automated tests, deployment evidence, cost review, and application runbook, diagnose it from evidence, apply the smallest reversible correction, and rerun acceptance checks.

1. Confirm scope, prerequisites, identities, dependencies, data, risks, and expected outcome.
2. Perform the course-specific configuration, development, administration, analysis, or business-process workflow.
3. Capture commands, settings, records, logs, screenshots, reports, metrics, or test results.
4. Compare the observed result with acceptance criteria and document corrective or preventive action.

Scenario Analysis

• Identify the technical or business decision and the stakeholders affected by it.
• Compare security, performance, reliability, compliance, cost, usability, and support trade-offs.
• Define rollback, recovery, communication, evidence, ownership, and escalation requirements.

Troubleshooting Guidance

Diagnose issues involving Vault keys, secrets, certificates, WAF awareness, and secure configuration, logs, metrics, traces, APM, alarms, and correlation identifiers, timeouts, retries, circuit breakers, concurrency, and fault isolation, automated tests, deployment evidence, cost review, and application runbook without making an unverified production change. Separate symptoms from causes, gather time-correlated evidence, test a reversible hypothesis, validate the correction, and record recurrence controls.

Validation Checklist

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

Lesson Outcome

Learners can apply Security, Observability, Resilience, Testing, and Developer Operations in a realistic Oracle Cloud Infrastructure Developer Professional: Hands-on Workshop scenario and defend the result with documented evidence.
