Deploy Web App to App Service

Foundations & App Service → Containers & AKS → DevOps & Security → Projects

Foundations & App Service · 1 — Host · ~6 min · App Service & SQL

What is this?

App Service hosts web apps and APIs without you managing VMs. You create a Web App, deploy code (ZIP, GitHub Actions, or Visual Studio), and configure settings.

Why should you care?

Most CloudVerse .NET APIs start here before containers — fastest path to HTTPS URL.

See it live — copy this example

Use an Azure lab/free subscription. Prefer Azure CLI or Portal. Delete idle App Service plans, SQL DBs, and AKS clusters when practice is done.

# Create RG + plan + web app (example names)
az group create -n rg-cloudverse-dev -l eastus
az appservice plan create -g rg-cloudverse-dev -n plan-cloudverse-dev --sku B1 --is-linux
az webapp create -g rg-cloudverse-dev -p plan-cloudverse-dev -n app-cloudverse-api-dev --runtime "DOTNETCORE:8.0"

What happened?

Resource group holds everything.
Plan is the compute size.
Web app is the site that gets your bits.

Practice next

Create RG, plan, and web app with unique names.
Deploy a hello API (VS publish or zip deploy).
Open the default *.azurewebsites.net URL.
Try Free/F1 only if available in your region.
Add a second slot later.

Remember

App Service = managed web host. Plan controls cost/scale. Deploy then configure settings.

API goes live

Sprint demo needs a public HTTPS endpoint.

Outcome: App Service URL serves your API.

What is a release pipeline and how does it differ from a build pipeline? Answer: A build pipeline (CI) compiles, tests, and packages your code — it produces artifacts. A release pipeline (CD) takes those artifacts and deploys them to different environments like Dev, QA, or Production. Example: ● Build Pipeline: Compiles your .NET app and outputs a .zip file. ● Release Pipeline: Takes that .zip and deploys it to Azure App Service. So, the build pipeline = create, and release pipeline = deliver.

Perform a Swap to move it into Production with zero downtime. Example (YAML): - task: AzureWebApp@1 inputs: Follow: azureSubscription: 'MyServiceConnection' appName: 'my-webapp' deployToSlotOrASE: true resourceGroupName: 'my-rg' slotName: 'staging' Then use: - task: AzureAppServiceManage@0 inputs: Action: 'Swap Slots' SourceSlot: 'staging' ResourceGroupName: 'my-rg' WebAppName: 'my-webapp' 7⃣ How do you perform rollback in case of a failed deployment?

There are several ways: What interviewers expect A clear definition tied to DevOps in Azure DevOps projects Trade-offs (performance, maintainability, security, cost) When you would and would not use it in production Real…

Assign proper RBAC roles (e.g., Contributor or Owner). Usage in pipeline: - task: AzureResourceManagerTemplateDeployment@3 inputs: azureResourceManagerConnection: 'MyServiceConnection' resourceGroupName: 'MyRG' location: 'East US' csmFile: 'infra/main.json' Example scenario: Your IaC pipeline uses the “ProdServiceConnection” to deploy Bicep templates to the production resource group, without developers ever seeing credentials. 4⃣ How can you automate environment creation and teardown?

You can automate creating and destroying environments (like dev, test, or staging) using pipeline logic and IaC tools. ✅ Example (Bicep – Create Environment): task: AzureCLI@2 inputs: azureSubscription: 'MyServiceConnect…

After deployment, Azure Pipelines can report live data to App Insights (like response time, failed requests, or exceptions). Example (YAML): - task: AzureCLI@2 inputs: azureSubscription: 'MyServiceConnection' scriptType: 'bash' scriptLocation: 'inlineScript' inlineScript: | echo "Checking App Insights availability..." az monitor metrics list --resource myapp --metric requests/count Example scenario: After a new deployment, your team monitors App Insights dashboards — noticing that response times increased by 20%. They can quickly roll back or optimize performance before users notice. ✅ Pro Tip: Combine these tools for full visibility: ● Azure Pipelines logs → Diagnose build/deployment failures. ● Azure Monitor + App Insights → Track live app performance. ● Power BI / Analytics → Measure DevOps effectiveness. ● Dashboards → Share live health status with your whole team. Follow: Infrastructure as Code (IaC) & Automation 1⃣ How do you provision infrastructure in Azure using ARM, Bicep, or Terraform via Azure DevOps?

You can automate infrastructure deployment directly from Azure Pipelines using ARM templates, Bicep files, or Terraform scripts. Each option defines your infrastructure as code — meaning servers, networks, and resources…
