Select 2Your organization is migrating an on-premises Kubernetes environment running containerized microservices to Oracle Cloud Infrastructure (OCI) using Oracle Container Engine for Kubernetes (OKE). Which two tasks must you include in the planning phase to ensure a successful migration?
- A
Review and update container images to meet OCI compliance requirements
- B
Immediately implement canary deployments in production to test performance
- C
Deploy application pods in OKE using default resource allocations
- D
Conduct capacity planning and an architecture design review for OKE
Show answer and explanation
Correct answers: A, D
Explanation
When migrating containerized workloads to OCI, it is essential to follow a phased approach. Planning involves evaluating the existing Kubernetes environment, preparing container images for OCI compatibility, performing capacity assessments, and aligning network and governance requirements with OCI. The official Oracle documentation recommends detailed planning and assessment before moving to implementation or canary testing. Refer to Oracle Container Engine for Kubernetes documentation for best practices and guidelines: https://docs.oracle.com/en/solutions/kubernetes-oci-overview/index.html.
- A. Correct.
Correct. During the planning phase, validating and updating container images (such as ensuring they comply with OCI security and configuration requirements) is key. This step prevents potential compatibility and security issues later in the migration lifecycle.
- B. Incorrect.
Incorrect. Implementing canary deployments in production is typically done during or after the migration/testing phase, not during the initial planning. While they are valuable for verifying changes in a production-like environment, they come after you have thoroughly planned and prepared your workloads.
- C. Incorrect.
Incorrect. Simply deploying application pods with default resource allocations lacks the essential capacity assessment. Resource requirements need to be carefully analyzed during the planning phase to ensure the right sizing and configurations. Blindly using default settings may lead to performance or cost inefficiencies.
- D. Correct.
Correct. Capacity planning and architecture design review are vital steps in the planning phase. You must assess your current workload requirements, design your OKE cluster with the appropriate node pools, and ensure that governance and network configurations align with expected growth and performance needs.
