I am trying to reduce the number of one-off App Service Plans my organisation has for a number of App Services. However, when clicking "Change App Service plan" within the App Service, often the App Service Plan I would like to move it to doesn't show up in the list.
What determines whether two app services can run on the same App Service Plan besides region? Is it just the Operating System, or also the stack? Does it have something to do with the resource group of either the App Service Plan or App service?
About change app service plan, there is a description in the office document: Move an app to another App Service plan.
About your problem, you said the target plan is not listed in the list, the most likely reason is that they are not in same App Service Environment. In the document it say all plans created with the same resource group and region combination are deployed into the same webspace.
So make sure your App Service Environments are same, like region and resource group before moving web. Hope this could help you, if you still have other problem please feel free to let me know.
Free has 10 and Shared has a quota of 100.
Think out how you want to group your applications though as keep in mind they will share the same compute resources if combining. Also if deploying infrastructure as code keep in mind now that there are more dependencies when combining the applications into one App Service Plan.

Ive looked around and cant understand it or find anything.
I have two app services deployed with their own associated app service plans.
they are deployed with terraform so follow the same process and parameters except for the name.
so why would one app service not be allowed to upgrade to P1V2 app service plans and the other can?
both are deployed to in the same way and the line from Microsoft, " underlying App Service deployment doesn’t support PremiumV2 " doesnt help much as I dont know what that means.
Any one?
Bueller?
App Services are deployed to what's called scale units. The newer scale units support Pv2 instances while older ones do not. The recommendation to make sure your app service plan lands on a scale unit that supports Pv2 is to deploy an ASP with Pv2 SKU and then scale down.

I have an ASP.NET core 3.1 based web api ready to deploy to Azure for production use. For test / development, I have been deploying it to a traditional app service on Azure which I believe is a shared Windows VM under the hood. I have been on F1 tier and it suits my needs for test and dev.
But for production, even the cheapest plan costs me $93.44 per month which I would like to avoid if I can.
In order to lower the cost, I have decided to containerize my app and deploy it using "web app for containers" or "azure container instances". My question is, based on your experience, which method will give me reasonable production-scale performance while minimize my monthly cost? Or would containerize my app save me any money at all?
Please note that I have evaluated Azure Functions and decided it is not what I would like to use.
For your requirements, first of all, you need to know that the Azure Container Instance benefits for its quick start and running. See this:
Azure Container Instances is a great solution for any scenario that
can operate in isolated containers, including simple applications,
task automation, and build jobs.
It's good for the simple application, but not good for scenarios where you need full container orchestration, including service discovery across multiple containers, automatic scaling, and coordinated application upgrades. And I think it's also not stable for the production use, it's more appropriate for the test.
And the Azure App Service is cost according to the service plan, the service plan billed on a per second basis. You can plan the use with time as you need and the App Service has more features than Container Instance. Or if you do not satisfied with App Service, maybe you can take a look at the Azure Kubernetes Service, it has more control and feature then the Container Instance.
As of beginning of 2022 looks like Container Instances and Web Apps for containers will be the same ~32eur which is a bit better than the app service ~50eur.
I'm looking to deploy a "Web App On Linux + MySQL" but am not sure what some of the features of the S1 Standard pricing tier mean.
"Up to 10 instance(s)" - What constitutes an instance?
"5 Slots" for "Web app staging" - What does this mean?
I'm trying to decide whether or not I need the S1 Standard offering or if B1 Basic is sufficient for my needs. Appreciate any insight from people better versed in Azure than I am.
"Up to 10 instance(s)" - What constitutes an instance?
You could refer to this official document.
When you create an app in App Service, it is put into an App Service plan. When the app runs, it runs on all the VM instances configured in the App Service plan. If multiple apps are in the same App Service plan, they all share the same VM instances. If you have multiple deployment slots for an app, all deployment slots also run on the same VM instances. If you enable diagnostic logs, perform backups, or run WebJobs, they also use CPU cycles and memory on these VM instances.
In this way, the App Service plan is the scale unit of the App Service apps. If the plan is configured to run five VM instances, then all apps in the plan run on all five instances. If the plan is configured for autoscaling, then all apps in the plan are scaled out together based on the autoscale settings.
For S1 standard, you could autoscale your app run 10 VM instances.
You also could could refer to this question.
"5 Slots" for "Web app staging" - What does this mean?
You could refer to this official document.
When you deploy your web app, web app on Linux, mobile back end, and API app to App Service, you can deploy to a separate deployment slot instead of the default production slot when running in the Standard or Premium App Service plan mode. Deployment slots are actually live apps with their own hostnames.
We are currently running several Azure App Services which are having trouble with PCI-DSS compliance, due to the fact that App Services have TLSv1.0 enabled, with no option to disable it. After reading around, it seems like App Service Environments will allow us to do just that. However, I can't seem to figure out how to migrate our existing app to the new service environment. Do we just have to create a new app from scratch?
I assume your existing apps have already been deployed into existing App Service Plan? If so, you cannot move, all you can do is to clone it into a new ASP which has been deployed into your ASE
Given the fact that an ASP’s location (within an ASE or in a shared public location) cannot be changed once it is created, you have to clone/duplicate the deployments when you scale your apps in this approach. It also implies that the order you create resources is ASE (optional), then ASP, and finally add App Service apps into an ASP.
Or you can see my ASP/ASE learning at my blog
We'd like to add instances to our Azure App Service plan to scale out. Everything we've got is stateless, apart from one app. Because of the way that app is used, if there is more than one instance of it things will quickly go crazy. We can work fix this eventually - we need to build in shared storage for its state - but at the moment we don't have enough the time.
Is there any way to scale out an app service plan, but indicate that particular apps should only ever be run on one host?
I'm assuming this isn't possible, however it turns out to be surprisingly easy to move an existing app between app service plans without having to recreate the configuration. I have gone down this route for now with an eye to fixing the clustering issue and moving the app back into the original app service plan later.
Did you think about using Cloud Services or Service Fabric? Cloud Services role model is what you are thinking of - you are able to scale only one component of the solution.
