Azure DevOps Environments and Deployment Jobs

1. What is an Azure DevOps Environment?

An Environment in Azure DevOps represents a deployment target, such as Dev, SIT, UAT, or Production.

It helps us manage deployments, track deployment history, and configure approvals.

Example:

Azure DevOps
    |
    └── Environments
          |
          ├── Dev
          ├── SIT
          ├── UAT
          └── Production

Why do we need it?

• Track which application version was deployed.

• Maintain deployment history.

• Configure manual approvals before deployment.

• Control deployment permissions.

• Manage deployment targets such as VMs and Kubernetes clusters.

2. What is a Deployment Job?

A Deployment Job is a special type of Azure Pipeline job used to deploy an application to an environment.

Unlike a normal job, it supports deployment history, environment tracking, and deployment strategies.

Example:

jobs:
- deployment: DeployUAT
  environment: 'UAT'
  strategy:
    runOnce:
      deploy:
        steps:
        - task: AzureWebApp@1
          inputs:
            azureSubscription: 'AzureConnection'
            appName: 'myapp-uat'
            package: '$(Pipeline.Workspace)/drop/webapp.zip'

3. How do they work together?

Azure Pipeline
      |
      v
Deployment Job
      |
      v
Environment: UAT
      |
      | Check Approval
      v
Approved?
      |
      | Yes
      v
Deploy to Azure App Service
      |
      v
Record Deployment History

Important: The Azure DevOps Environment is a logical deployment target. It is not automatically an Azure App Service or a physical server.

5. Interview answer

Question: What are Azure DevOps Environments and Deployment Jobs?

Answer:

"Azure DevOps Environments represent deployment targets such as Dev, SIT, UAT, and Production.

A Deployment Job is a special pipeline job used to deploy an application to a specific environment.

We use Environments to manage approvals, track deployment history, and control deployments.

For example, our pipeline uses a deployment job to deploy an ASP.NET Core application to UAT. Before deployment, Azure DevOps checks the configured approval requirements."

Remember: Environment = Where we deploy; Deployment Job = How we deploy.
