AI-200 Containerized AI Workloads Practice Question
You need to deploy a microservice application that consists of an API gateway and an AI model inference container. The solution must scale automatically based on HTTP traffic and support zero scaling when idle to reduce costs, without requiring complex Kubernetes cluster management. Which service is best suited for this?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Container Apps
Azure Container Apps (ACA) provides serverless container hosting built on top of Kubernetes, supporting KEDA-based autoscaling including scaling to zero based on HTTP traffic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Azure App Service for Containers
Why it's wrong here
While App Service supports containers, Container Apps is optimized for microservices and event-driven architectures with native KEDA.
- ✗
Azure Batch
Why it's wrong here
Azure Batch is designed for large-scale parallel and high-performance computing batch jobs, not real-time HTTP microservices.
- ✓
Azure Container Apps
Why this is correct
Azure Container Apps provides fully managed serverless containers with built-in KEDA scaling, including scaling to zero.
- ✗
Azure Kubernetes Service (AKS)
Why it's wrong here
AKS requires managing the underlying Kubernetes cluster, which introduces operational overhead for simple serverless deployments.
