DO241 Cloud-Native API Administration with Red Hat 3scale API Management with Exam — Lesson 2: Applications, Accounts, Plans, Metrics, Methods, Limits, and Monetization

Learning Objectives

• Configure the main services, objects, and controls involved in applications, accounts, and application plans.
• Apply metrics and methods and limits and monetization while preserving reviewable technical evidence.
• Recognize and correct the risk where a valid command creates the wrong outcome because variables, identity, or sequencing are incorrect.

Detailed Topics

• applications: 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.
• accounts: 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.
• application plans: 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.
• metrics and methods: 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.
• limits and monetization: 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 applications, accounts, plans, metrics, methods, limits, and monetization by tracing the relevant architecture, commands, configuration, messages, and evidence. The walkthrough highlights how a valid command creates the wrong outcome because variables, identity, or sequencing are incorrect and shows how to isolate the cause without masking dependent issues.

Hands-On Exercise

Implement the core workflow and compare expected versus observed behavior for Applications, Accounts, Plans, Metrics, Methods, Limits, and Monetization. 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 applications in the stated scenario.
• Compare two approaches for metrics and methods 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 configuration, permissions, sequencing, and functional behavior separately, then correlate logs, events, commands, and configuration history. Do not accept the initial assumption that a valid command creates the wrong outcome because variables, identity, or sequencing are incorrect; confirm the cause with a reproducible retest.

Validation Checklist

• The required configuration, permissions, sequencing, and functional behavior 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 Applications, Accounts, Plans, Metrics, Methods, Limits, and Monetization, 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.
