Azure CDN Standard from Microsoft (classic) will be retired - Will Azure Front Door cost me money?

Question

I've received an email stating that Azure CDN will be retired and I should migrate to Azure Front Door Standard or Premium.

I am only storing a few dozen images and some JS files in CDN and it costs me < 0.01p per month.

If I migrate to Azure Front Door are my running costs likely to rise? If so, I will simply move my images and scripts into my App Service, but I cannot find much information on the running costs just to maintain a tiny CDN.

Btw, I only Azure for hosting my personal web site so I don't want to pay a lot for it, my Linux app service plan only costs me about £12 per month GBP, but I don't really want to pay any more for a site that only gets 1 user a month and that is normally me :D

Hello , Welcome to MS Q&A

Yes, your running costs are likely to rise if you migrate from Azure CDN (Classic) to Azure Front Door Standard or Premium, even for very light usage.

Key points:

• Azure Front Door Standard/Premium has a minimum base charge of ~$35/month (Standard) or ~$300/month (Premium), regardless of usage. See official pricing
• There is no “pay only for what you use” tier for Front Door; the base fee applies even if you only serve a few files.
• Azure CDN (Classic) allowed for extremely low-cost, low-usage scenarios, but Front Door is designed for enterprise/global scale.

Recommendation for your scenario:

• If you only serve a few static files and cost is a concern, move your images and JS files into your App Service’s wwwroot.
• You can serve static files directly from your App Service at no extra cost.
• Alternatively, consider using GitHub Pages, Azure Static Web Apps Free tier, or other free/low-cost static hosting if you want to further reduce costs.
