By the end of this session

How App Service plans and web apps fit together
A running web app at your own azurewebsites.net address
Your own code deployed from Cloud Shell
Everything deleted again, for a few cents in total

2 / 13

Two things you create, not one

App Service plan	Server capacity you pay for: size, region, OS	Renting a kitchen
Web app	Your application, running on the plan	The restaurant using it

3 / 13

Watch the pricing plan

Free F1: $0, for learning
Basic B1: about $12.41 a month, billed hourly
Premium: $53+ a month, for production

4 / 13

Remember

The default is not the cheapest

After upgrading, the form pre-selected Premium V3 at about $56 a month. Always check the pricing plan before you select Create.

5 / 13

When Azure says no

New trial subscriptions start with an App Service quota of 0
Even the free F1 plan is blocked
Another region doesn't help

6 / 13

Getting past the quota

1. Upgrade to pay-as-you-go
2. Request B1 VMs = 1 in your region
3. If declined, open a free support request

7 / 13

Your new web app

Node 24 LTS on Linux, East US
Plan asp-learnazure-dev-eus, B1
Default domain ends in .azurewebsites.net

8 / 13

Deploy from Cloud Shell

server.js listens on process.env.PORT
package.json has a start script
zip, then az webapp deploy --type zip

9 / 13

Live on the internet

Refresh the default domain
If it fails: az webapp log tail

10 / 13

Remember

Clean up so you only pay cents

A plan bills by the hour whether anyone visits or not. az webapp delete removes the app, and the plan with it when it was the last app. Keep the empty resource group for next time.

11 / 13

Quick check

Delete the app but keep the plan. Still paying?
"Current Limit (F1 VMs): 0". Will another region fix it?
Works on port 3000 locally, errors on Azure. First check?
Which pricing plan does the form choose by default?

Answers are in the post.

Next: storage accounts, blobs and access keys

Store files in Azure, find the cheapest options, and learn why you should almost never hand out an access key.
