1Z0-1123-25 Question 102
Select 3Benson Inc. is planning to migrate their microservices-based, containerized e-commerce application from an on-premises environment to Oracle Cloud Infrastructure (OCI). They want to ensure minimal downtime and align their architecture with OCI best practices. Which three phases should they prioritize to successfully migrate their containerized workloads to OCI?
- A
Assess and plan the container migration strategy based on application requirements and resource sizing estimates
- B
Immediately push existing Docker images to OCI without verifying dependencies or performing any compatibility checks
- C
Conduct a pilot or staging test to validate application behavior in OCI� container environment
- D
Move to a third-party cloud provider first and then replicate containers to OCI for minimal downtime
- E
Deploy to the production environment on OCI after successful tests, and monitor performance for continuous optimization
Show answer and explanation
Correct answers: A, C, E
Explanation
When migrating containerized workloads to OCI, it is critical to follow a phased approach: (1) Assess and plan the requirements and architecture, (2) test the environment in a pilot or staging setting to identify potential issues, and (3) deploy in production followed by monitoring and optimization. Oracle Cloud Infrastructure documentation emphasizes these pre-deployment checks and continuous performance evaluations to avoid unexpected downtime and ensure optimal resource usage.
- A. Correct.
Correct. A thorough assessment and planning phase is essential to understand the application� resource requirements (e.g., CPU, memory), dependencies, and compliance needs. This planning helps identify which OCI services�such as Container Engine for Kubernetes or Container Instances�best fit the workload.
- B. Incorrect.
Incorrect. Simply pushing Docker images to OCI without verifying dependencies, versions, and compatibility can lead to runtime errors and service interruptions. Properly validating images prevents avoidable downtime and troubleshooting headaches.
- C. Correct.
Correct. Conducting a pilot or staging test helps validate the container environment, networking configurations, and service integrations within OCI. This phase ensures that any issues can be discovered and remedied before going live.
- D. Incorrect.
Incorrect. Migrating to a third-party cloud before moving to OCI often adds unnecessary complexity and cost. Moreover, it can introduce additional security and compliance concerns, making the process more error-prone.
- E. Correct.
Correct. After successful tests in a staging environment, deploying in production with performance monitoring and iterative optimization is a best practice. Monitoring resource utilization and fine-tuning your setup in OCI ensures long-term reliability and cost-efficiency.
