Oracle Cloud Infrastructure Developer Professional (2024): Hands-On Workshop — Lesson 2: Serverless Functions, API Gateway, Events, Streaming, Queues, and Integrations

Learning Objectives

• Trace how serverless functions, api gateway, events, streaming, queues, and integrations changes data, application behavior, accounting, performance, or user experience.
• Configure a repeatable workflow with defined inputs, checkpoints, outputs, and exception paths.
• Defend functional correctness, access control, data quality, recoverability, and support readiness.

Detailed Topics

• Serverless Functions
• API Gateway
• Events
• Streaming
• Queues
• Integrations
• requirements, ownership, prerequisites, data, and acceptance criteria for serverless functions, api gateway, events, streaming, queues, and integrations
• security, controls, integration, performance, recovery, and support implications for serverless functions, api gateway, events, streaming, queues, and integrations

Instructor Demonstration

Demonstrate serverless functions, api gateway, events, streaming, queues, and integrations within a 2024 OCI application composed of APIs, event-driven services, containers, and automated releases with production-grade security and monitoring. Use representative data and capture resource configuration, policies, function and API responses, event flows, container builds, Kubernetes resources, infrastructure plans, deployment runs, metrics, logs, and traces so another practitioner can independently verify the result.

Hands-On Exercise

Complete a controlled Oracle Cloud Infrastructure Developer Professional (2024): Hands-On Workshop exercise focused on serverless functions, api gateway, events, streaming, queues, and integrations. Introduce one realistic failure involving misconfigured networks, broad IAM, event loss, API exposure, image vulnerabilities, configuration drift, failed releases, and insufficient production telemetry; isolate the cause, apply the smallest reversible correction, and rerun the acceptance checks.

1. Record the requirement, environment, identities, dependencies, data, controls, and expected result.
2. Perform the lesson workflow and capture evidence before and after each material change.
3. Test normal, boundary, failure, security, reconciliation, recovery, and operational conditions relevant to the topic.
4. Document the root cause, correction, rollback, owner, support action, and next improvement priority.

Scenario Analysis

• Separate mandatory business requirements from convenience requests and local workarounds.
• Evaluate data, security, control, usability, performance, integration, and audit trade-offs.
• Choose the smallest supportable change and define evidence for normal, boundary, and failure conditions.

Troubleshooting Guidance

When serverless functions, api gateway, events, streaming, queues, and integrations does not produce the expected result, confirm scope, effective dates, identities, data context, dependencies, and recent changes. Review the Oracle-specific logs, reports, traces, calculations, workflow history, transaction status, or diagnostic output relevant to the lesson. Test one reversible hypothesis at a time and verify that the correction does not create misconfigured networks, broad IAM, event loss, API exposure, image vulnerabilities, configuration drift, failed releases, and insufficient production telemetry elsewhere in the process.

Validation Checklist

• Prerequisites, ownership, data context, settings, and expected outcomes are documented.
• The workflow is reproducible and supported by resource configuration, policies, function and API responses, event flows, container builds, Kubernetes resources, infrastructure plans, deployment runs, metrics, logs, and traces.
• Security, controls, data quality, integration, performance, recovery, and support conditions are reviewed.
• Exceptions, corrective action, rollback, approvals, monitoring, and handover are recorded.

Lesson Outcome

Learners can apply Serverless Functions, API Gateway, Events, Streaming, Queues, and Integrations in a realistic Oracle Cloud Infrastructure Developer Professional (2024): Hands-On Workshop situation and defend the result with course-specific evidence.
