What is this?

Event Grid Basics 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.

# Event Grid Basics
# 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 Event Grid Basics simply. You practiced one Azure action. You know a cost or security risk.

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…

What are pipeline templates and how are they used? Answer: Templates let you reuse pipeline steps across projects — great for standardization. Example: You can create a reusable file: 📄 .azure-pipelines/build-template.yml steps: - script: dotnet restore - script: dotnet build Then in your main pipeline: extends: template: .azure-pipelines/build-template.yml This keeps your YAML DRY (Don’t Repeat Yourself) and consistent.
