Java on OCI: Develop a REST-Based Microservice

Course Description

Java on OCI: Develop a REST-Based Microservice develops practical capability in developing and deploying a Java REST microservice on OCI with API design, persistence, containers, managed services, security, and observability. The learning path is organized around a small inventory microservice packaged, deployed, secured, and monitored on OCI.

Learners progress from product architecture and workflow understanding into configuration, development, analysis, validation, troubleshooting, and operational handoff. Every lesson uses the controls, tools, data structures, risks, failure modes, and decisions relevant to this exact Oracle pathway.

The content is independently written for SkillDynamo using the supplied source page for title, update date, and topic alignment. Learners finish with reproducible evidence, a course-specific implementation record or runbook, and a prioritized improvement action.

What You Will Learn

• Explain and apply resource modeling, URIs, HTTP methods, status codes, and idempotency within Java on OCI: Develop a REST-Based Microservice.
• Configure, validate, or troubleshoot Helidon or Micronaut-style project structure, configuration, and dependency setup, DTOs, JSON binding, bean validation, and domain boundaries, and consistent error responses, logging context, and API tests using course-specific evidence.
• Explain and apply database access patterns, connection pools, repositories, and transactions within Java on OCI: Develop a REST-Based Microservice.
• Configure, validate, or troubleshoot configuration profiles, environment variables, feature flags, and portability, Vault secrets, resource principals, policies, and least privilege, and retry, timeout, duplicate request, consistency, and failure tests using course-specific evidence.
• Explain and apply container images, multi-stage builds, non-root execution, and local tests within Java on OCI: Develop a REST-Based Microservice.
• Configure, validate, or troubleshoot OCI Registry repositories, authentication, tags, and image scanning, deployment to compute or OKE, services, health probes, and scaling, and API Gateway routes, authentication awareness, throttling, and endpoint validation using course-specific evidence.
• Explain and apply structured logs, metrics, tracing, correlation IDs, alarms, and dashboards within Java on OCI: Develop a REST-Based Microservice.
• Configure, validate, or troubleshoot timeouts, retries, circuit breakers, bulkheads, and graceful degradation, TLS, headers, input safety, token validation, and dependency security, and automated tests, release checks, rollback, cost review, and microservice runbook using course-specific evidence.

SkillDynamo Training Approach

The training follows a small inventory microservice packaged, deployed, secured, and monitored on OCI. Activities combine product-specific demonstrations, guided implementation, hands-on exercises, scenario analysis, validation checklists, structured troubleshooting, solution review, and a final improvement plan. Learners document assumptions, settings, commands or transactions, outputs, exceptions, corrective actions, security and governance trade-offs, rollback needs, and operational ownership.
