能否通过多个免费Azure App Service Plan突破单Azure账户10个免费Web应用限制？超量是否自动计费？

Great questions—let’s break this down clearly based on Azure’s current free tier rules:

Can I have multiple free App Service Plans to host more than 10 free sites on one Azure account? #

Yes, but with a key regional restriction:

• Azure allows one free App Service Plan (F1 SKU) per region per subscription.
• Each free plan can host up to 10 web apps (websites).

So to host more than 10 free sites, you can create additional free plans in different Azure regions. For example:

• Create a free plan in East US, deploy 10 sites there
• Create another free plan in West Europe, deploy another 10 sites there
• Repeat for other regions you want to use

This way, you can scale past the 10-site limit without paying, as long as you stay within each region’s 1 free plan / 10 apps quota.

Will I get charged automatically if I have more than 10 free sites, or can I avoid billing with multiple free plans? #

It depends on how you exceed the 10-site limit:

• If you try to add an 11th site to a single free plan: Azure will block you from doing this unless you upgrade the plan to a paid SKU (like B1, B2, etc.). Upgrading will trigger billing for the plan, so this is where costs would kick in.
• If you use multiple free plans across different regions: As long as each plan stays within its 10-app limit and you don’t exceed the 1 free plan per region rule, you won’t get charged automatically. This is a valid way to avoid billing while hosting more than 10 free sites.

Just a quick note to keep in mind: Free plans have resource limits (like CPU time caps, memory limits) that apply to all apps in the plan. If your apps exceed these limits, they might be throttled—but you won’t get charged for throttling, just reduced performance.
