Can we save cost if we stop the services from App Service Plan

Gosavi, Pravin 0

Hi,

We are currently using App service Plan with Pricing Tier - Premium V2 (P1v2: 2).

I am stopping some services from App Service Plan to practically check if Stopping the services can actually save the cost.

In Pricing calculator it is showing like 1 Instance * 730 Hours.

Any Thought on this?

Thanks!

Can we make instance count=0 for non working hours?

Hello Gosavi, Welcome to MS Q&A

Stopping services in an App Service Plan can help save costs, particularly in dedicated compute tiers (Basic, Standard, Premium, etc.) where you are charged based on the number of VM instances running. If you stop the services, you effectively reduce the number of active instances, which can lead to lower charges. However, it's important to note that the Pricing Calculator reflects costs based on the selected pricing tier and the number of instances, so if you stop services, you would need to adjust the instance count in the calculator to see the potential savings.

Also, in Azure App Service Plans, you cannot set the instance count to 0. The minimum number of instances must be at least 1, as the always ready instances setting specifies the minimum number of instances that should be running to handle incoming requests.

Then how Stopping services in an App Service Plan can help save costs? Cost will be there for 1 instance count always. That means it is not saving the cost by just stopping the services right?

The cost savings come from reducing the number of instances or scaling down to a lower pricing tier. If you need to save costs, consider the following options:

Scale Down: Reduce the number of instances or switch to a lower pricing tier during non-working hours.

Auto-Scaling: Configure auto-scaling rules to adjust the number of instances based on demand, ensuring you only pay for what you use.

Free/SharedPricing: Use the Free/shared tier for non-production environments to reduce costs.

These strategies can help optimize costs while maintaining the necessary performance and availability for your applications.

Yes Instance count dedicated tiers (Basic and higher) can be scaled out, and each scaled out instance accrues costs which is basically my second point conifgure autoscaling

Optimize costs

At a basic level, App Service apps are charged by the App Service plan that hosts them. The costs associated with your App Service deployment depend on a few main factors:

Pricing tier Otherwise known as the SKU of the App Service plan. Higher tiers provide more CPU cores, memory, storage, or features, or combinations of them.

Instance count dedicated tiers (Basic and higher) can be scaled out, and each scaled out instance accrues costs.

Stamp fee In the Isolated tier, a flat fee is accrued on your App Service environment, regardless of how many apps or worker instances are hosted.

@Gosavi, Pravin Thanks for posting your question in Microsoft Q&A, apologize for any inconvenience caused on this.

Unfortunately, there is no way to stop the app service plan. Even if you stop all the webapp inside the app service plan you will be charged as per the pricing mentioned here based on the SKU size of the app service plan.

The only suggestion/workaround to reduce the cost saving is to downgrade the app service plan to either Free or shared tiers during non-working hours.

Hope this helps, let me know if you have any further questions on this.

Hi,

Stopping a web app does not save cost. You are still charged for the instances in the App Service Plan, even if all web apps in the plan are stopped. Please see below from pricing FAQ:

One potential method to save money is to switch to Free/lower cost SKU when not using web apps, and then switch back to Premium when you want to use them again. If running multiple instances (as in your case), you could reduce (but not eliminate) some costs by scaling in from 2 instances to 1.
