100% OFF 1Z0-1084-25 : OCI 2025 Developer Professional PRACTICE EXAM Coupon Code

This practical, instructor-led (or self-paced) course prepares developers to design, build, secure, test, observe, and operate cloud-native applications on Oracle Cloud Infrastructure — with focused alignment to the 1Z0-1084-25 Oracle Cloud Infrastructure 2025 Developer Professional exam objectives. You’ll move quickly from fundamentals to real-world labs: containerizing apps, deploying to OKE, adding service mesh traffic controls and mTLS, building serverless functions and API integrations, implementing streaming/queue patterns, securing secrets with Vault, and instrumenting apps for monitoring, logging and tracing.

Who this course is for

• Application developers preparing for the 1Z0-1084-25 certification.

• DevOps/SRE engineers who need to operate cloud-native services on OCI.

• Architects and team leads who want a practical playbook for OCI developer services.

  
  

Key outcomes (what you will be able to do)

After completing this course you will be able to:

1. Build, tag and publish container images to OCIR and deploy modern microservices to OKE.

2. Configure service-to-service traffic control, observability and security using OCI Service Mesh.

3. Design and deploy serverless workflows using Oracle Functions and API Gateway, and wire them to Events/Streaming.

4. Implement reliable messaging and streaming pipelines using OCI Queue and OCI Streaming.

5. Secure secrets and keys with OCI Vault and enforce least-privilege access via IAM policies.

6. Implement automated testing strategies and basic chaos/resilience checks for microservices.

7. Instrument applications and platform resources using OCI Monitoring, Logging and Tracing to create alerts and dashboards.

8. Confidently apply knowledge and practical experience to pass the 1Z0-1084-25 certification.

Module Titles & Detailed Descriptions

1. Containerization & OCIR: Building and Managing Docker Images

Hands-on workshop covering Dockerfile best practices, multi-stage builds, image optimization, tagging strategies, and pushing/pulling images to Oracle Cloud Infrastructure Registry (OCIR). Lab: containerize a sample microservice and publish two versions to OCIR.

2. Deploying Applications on OKE: Clusters, Node Pools & kubectl

Create and configure OKE clusters and node pools, generate kubeconfig, deploy manifests (Deployments, Services, Ingress), and use kubectl to manage rollouts and troubleshooting. Lab: deploy a two-service app behind an ingress controller and perform a controlled rollback.

3. Traffic Control & Security with OCI Service Mesh

Understand Istio/Service Mesh concepts as implemented by OCI Service Mesh: virtual services, routing rules, canary releases, mutual TLS, policy enforcement and observability integration. Lab: implement a 10% canary, enable mTLS, and use mesh telemetry to trace requests.

4. Serverless Development: Oracle Functions & API Gateway

Build, test and deploy serverless functions (Fn OCI Functions), package dependencies, and wire functions to API Gateway endpoints and OCI Events. Lab: implement a REST endpoint backed by a function that persists data to a serverless datastore or object storage.

5. Eventing and Messaging: OCI Streaming & OCI Queue Patterns

Learn when to use Streaming vs Queue, working with partitions, retention, producers/consumers, SDK examples, and common patterns (pub/sub, fan-out, event sourcing). Lab: implement a producer that streams user events and a consumer that processes and stores results.

6. Secrets & Access Management with OCI Vault and IAM

Secure application secrets at runtime using OCI Vault (keys and secrets), integrate Vault access with functions and Kubernetes pods, and author least-privilege IAM policies. Lab: store API keys in Vault and access them from a function and an OKE pod (without hard-coding).

7. Testing & Resilience: Unit, Integration, Contract and Chaos Tests

Best practices for test pyramids in cloud-native apps: unit tests, integration tests, consumer-provider contract tests, and simple chaos tests (latency/error injection). Lab: add unit integration tests to a microservice and run them in CI (sample pipeline).

8. Observability: Monitoring, Logging, Tracing, Alerts & Dashboards

Instrument apps with structured logging and distributed tracing; create metric queries, alarms, log groups and dashboard visualizations in OCI Monitoring and Logging. Lab: create an alert that fires on elevated 5xx rate and drill into traces to find the root cause.

Prerequisites (short checklist)

• Basic programming in Python/Java/Node.js/Go; comfort with a CLI; Git basics; Docker basics; OCI account with Cloud Shell. (Full checklist and install checks included in pre-course materials.)
