AZ-305 · Question 42 · Domain 4.1: Design a compute solution
A startup is building a microservices architecture using containers.
They have 15 different microservices that need to communicate with each other. They want a fully managed serverless container service that supports Kubernetes Event-driven Autoscaling (KEDA), Distributed Application Runtime (Dapr), and scales to zero when there is no traffic. They do not want to manage underlying VMs or Kubernetes cluster upgrades.
Which compute service should you recommend?

Which compute service should you recommend?
Answer options:
A.
Azure Container Apps
B.
Azure Kubernetes Service (AKS)
C.
Azure Container Instances (ACI)
D.
Azure App Service
How to approach this question
Look for the combination of 'serverless containers', 'microservices', 'KEDA', and 'Dapr'. This defines Azure Container Apps.
Full Answer
A.Azure Container Apps✓ Correct
Azure Container Apps is a fully managed serverless container service built for microservices. It is built on top of AKS but abstracts the Kubernetes API and cluster management away from the user. It natively integrates with KEDA for event-driven autoscaling (including scaling to zero) and Dapr for building resilient microservices. ACI is too simple for complex microservices, and AKS requires too much management overhead.
Common mistakes
Choosing AKS because 'microservices' are mentioned, ignoring the strict requirement of 'do not want to manage Kubernetes cluster upgrades'.
