What is this?

Serverless Production Notes covers serverless and messaging patterns on Azure.

Why should you care?

Async work and integrations should not block your API thread.

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.

# Serverless Production Notes
# Functions / Service Bus / Event Grid — sketch the trigger and the handler

What happened?

Name the trigger, the message contract, and the failure/retry behavior.
Follow the steps below — typing the code yourself is the fastest way to learn.

Practice next

Run the CLI/portal steps in a lab subscription.
Write the resource names you used.
Note estimated monthly cost for the SKU.
Repeat in a second region (conceptually).
Add the resource to a simple architecture diagram.

Remember

You can explain Serverless Production Notes simply. You practiced one Azure action. You know a cost or security risk.

How do you design a production-grade ASP.NET Core

pplication in Azure? What interviewers expect: They are testing architecture thinking, not just service knowledge. Strong Answer (Real-world level): In production, I never deploy a standalone ASP.NET Core app. I design a…

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.

Explain Azure Service Bus with a real production use case Strong Answer:

zure Service Bus is a reliable message broker used to decouple services and enable synchronous communication. Real-time Example: In a payment processing system: Without Service Bus: Order service calls Payment API direct…

Use versioned artifacts — keep your last working package and redeploy it. Example: If your new API build breaks production, you can quickly redeploy the previous successful release version from Azure DevOps → Releases → “Redeploy”. 8⃣ How do you deploy infrastructure using ARM templates or Bicep in Azure DevOps?

You can deploy Infrastructure as Code (IaC) directly from your pipeline using ARM or Bicep files. Follow: Example (YAML): task: AzureResourceManagerTemplateDeployment@3 inputs: deploymentScope: 'Resource Group' azureReso…

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…
