What is this?

Logic Apps Overview 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.

# Logic Apps Overview
# 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 Logic Apps Overview simply. You practiced one Azure action. You know a cost or security risk.

Reference the artifact (.zip) from your build pipeline. Example scenario: A .NET Core app gets built, zipped, and deployed automatically to the Staging slot of an Azure Web App after successful testing. 5⃣ How do you manage configuration transformations (e.g., web.config or appsettings.json)? Follow:

You can use XML or JSON transformation tasks in your release pipeline to adjust settings per environment. Example (Classic): Add a File Transform or Replace Tokens task. Replace values like database connection strings or…

Testing and validating pipeline parity. Scenario: A company using Jenkins moves to Azure DevOps to unify code and pipelines. They convert Jenkinsfile logic to YAML, using tasks like DotNetCoreCLI@2 and AzureWebApp@1. Eventually, builds run in Azure-hosted agents with better visibility and governance. 11⃣ How would you implement zero-downtime deployment for an ASP.NET Core API?

Zero-downtime means your API stays live while deploying new versions. Ways to achieve it: Use Azure App Service Deployment Slots (swap after warm-up). Use Blue-Green or Rolling Deployment strategy. Run health checks befo…
