Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
OCI Functions
Why it's wrong here
OCI Functions are for event-driven, short-lived execution code rather than general always-on web application containers.
- ✓
OCI Container Instances
Why this is correct
Container Instances are serverless containers that let you run applications instantly without managing underlying VMs.

Oracle Container Engine for Kubernetes (OKE)
Why it's wrong here
OKE is designed for complex cluster orchestration and management, which is overkill for a simple lightweight deployment.

Compute Standard Flex Instances
Why it's wrong here
Virtual machine instances require OS management, patching, and provisioning overhead.
