Choosing the Right Azure Service

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

DevOps & Security · 3 — Operate · ~10 min · Platform Services

What is this?

Choosing the Right Azure Service helps you pick the right Azure building block.

Why should you care?

Over-architecting burns budget; under-architecting blocks scale.

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.

# Choosing the Right Azure Service
# Compare services: when App Service vs Functions vs AKS vs APIM

What happened?

Write a one-line “use when / avoid when” for this service.
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 Choosing the Right Azure Service simply. You practiced one Azure action. You know a cost or security risk.

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.
