DO241 Cloud-Native API Administration with Red Hat 3scale API Management with Exam — Lesson 3: APIcast Gateways, Policies, Authentication, Security, Routing, and Deployment

Learning Objectives

• Evaluate security, resilience, integration, and exception handling for APIcast, policies, and authentication.
• Apply security and routing and deployment while preserving reviewable technical evidence.
• Recognize and correct the risk where the design works normally but fails under scale, dependency loss, policy enforcement, or integration delay.

Detailed Topics

• APIcast: apply the concept to an API platform team publishing and governing enterprise APIs through 3scale, record the relevant settings or decisions, and explain the operational consequence.
• policies: apply the concept to an API platform team publishing and governing enterprise APIs through 3scale, record the relevant settings or decisions, and explain the operational consequence.
• authentication: apply the concept to an API platform team publishing and governing enterprise APIs through 3scale, record the relevant settings or decisions, and explain the operational consequence.
• security: apply the concept to an API platform team publishing and governing enterprise APIs through 3scale, record the relevant settings or decisions, and explain the operational consequence.
• routing and deployment: apply the concept to an API platform team publishing and governing enterprise APIs through 3scale, record the relevant settings or decisions, and explain the operational consequence.

Instructor Demonstration

The instructor demonstrates apicast gateways, policies, authentication, security, routing, and deployment by tracing the relevant architecture, commands, configuration, messages, and evidence. The walkthrough highlights how the design works normally but fails under scale, dependency loss, policy enforcement, or integration delay and shows how to isolate the cause without masking dependent issues.

Hands-On Exercise

Introduce a controlled boundary condition and test recovery for APIcast Gateways, Policies, Authentication, Security, Routing, and Deployment. Add verified outcomes to the 3scale API product configuration, policy and security evidence, portal setup, and operations runbook.

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 APIcast in the stated scenario.
• Compare two approaches for security and explain the security, reliability, and support trade-offs.
• Decide what evidence must be retained in the 3scale API product configuration, policy and security evidence, portal setup, and operations runbook before operational acceptance.

Troubleshooting Guidance

Begin with the first observable difference from the expected result. Check security, integration, boundary conditions, and resilience separately, then correlate logs, events, commands, and configuration history. Do not accept the initial assumption that the design works normally but fails under scale, dependency loss, policy enforcement, or integration delay; confirm the cause with a reproducible retest.

Validation Checklist

• The required security, integration, boundary conditions, and resilience were checked and recorded.
• The normal path and a course-specific exception were tested.
• The 3scale API product configuration, policy and security evidence, portal setup, and operations runbook 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 APIcast Gateways, Policies, Authentication, Security, Routing, and Deployment, explain the observed Red Hat platform behavior, and support the result with a reviewable 3scale API product configuration, policy and security evidence, portal setup, and operations runbook.
