You are designing a build pipeline in Azure Pipelines.
The pipeline requires a self-hosted agent. The build pipeline will run once daily and will take 30 minutes to complete.
You need to recommend a compute type for the agent. The solution must minimize costs.
What should you recommend?
A. an Azure Kubernetes Service (AKS) cluster
B. Azure Container Instances
C. an Azure virtual machine scale set
D. Azure virtual machines
Correct Answer: B
Explanation/Reference:
If your pipelines are in Azure Pipelines, then you’ve got a convenient option to run your jobs using a Microsoft-hosted agent. With Microsoft-hosted agents, maintenance and upgrades are taken care of for you. Each time you run a pipeline, you get a fresh virtual machine. The virtual machine is discarded after one use. Microsoft-hosted agents can run jobs directly on the VM or in a container.
Note: You can try a Microsoft-hosted agent for no charge.

running an Azure Container Instance is cheaper then running a Virtual Machine (with the mandatory operations costs) but it’s still best practice obviously to keep the costs down as much as possible.
