If you are planning to use Azure DevOps, it is mandatory to have understanding of Agent Pool. To build or run your code in a build pipelines you need Agents in Azure DevOps service. When you run a job in a build, Agent in Agent Pool support the process.
Go to project settings and click on Agent Pools. By default there are 2 pools exist.
Azure Pipelines hosted pool,(Each time you run a pipeline, you get a fresh virtual machine.)
You can manage these pools in Azure DevOps Yaml file as well
jobs:

pool:
vmImage: 'ubuntu-18.04'

In Azure Pipelines, you can run parallel jobs on Microsoft-hosted infrastructure or on your own (self-hosted) infrastructure.
