I am learning Azure and I have a question about App Service Plans.
I understand that an App Service Plan has an amount of RAM memory for each virtual machine instance. However, when it comes to storage space, I have a doubt if every time we create a virtual machine instance it is consuming disk space in the plan. For example, I have an application that consumes 1GB with a VM instance. If we scale out this plan and create 3 VM instances, will it take up 3GB of disk space? I understand the instances as copies of the content of the Plan, therefore I understand that for each instance the disk space consumption is multiplied by two. Is that so?
Thank you very much for your responses,
All the best.
SOLUTION
From Azure's own description of its plans, I conclude that each Plan provides ACU, RAM and disk space FOR EACH INSTANCE, not for the total plan.
In the example in the image, each instance has 210 ACUs, 3.5GB of memory and 250GB of storage.

i have isolated i2 service plan the app service runs windows .net web apps .
the local\temp keeps filling up.(I have a process to delete files but it sometimes can't keep up)
should I just attach a azure disk drive "E"?
Or is there a way to increase temp size?
It seems that you can attach a azure disk drive, but according to this post, the disk usage amount seems to be based on SKU. In other words, the higher the SKU level, the larger the disk size that can be used, and the size cannot be specified manually. If possible, you can try to scale to I3.
Unfortunately, you cannot increase the temp folder size inside a App Service. If you wish to increase temp space you can do it by scaling up the app service plan to higher tiers.
The “Disk Space” depends on the App Service plan you're using. It's 1 GB for Free, 10 GB for Basic, 50 GB for Standard and 250 GB for Premium, refer the document for more details on these limits: https://azure.microsoft.com/en-us/pricing/details/app-service/.
App Service also limits the amount of temporary local storage available to each app to prevent individual apps from consuming excessive amounts of local file storage.
Here is the information where you can know about the files that are dealt on Azure WebApp (Persisted files, Temporary files and Machine level read-only files) and there limits as well
Refer the below blog which will help you in understanding the disk space availability
Azure App Service - What is taking my disk space for my Azure Web App
I have created a App Service plan in Azure and under that service plan runs 14 applications.
Now that particular service plan has a pricing tier of Standard and Instance Size of Large, which is S3
S3 Cores: 4 RAM: 7 GB STORAGE:50 GB.
Do these 14 apps share the memory and storage that is available , so only 7G for the 14 apps and 50G of storage for the 14 apps aswell ? If so how can i see how much each is consuming in Azure ?
The short answer is Yes, different plans do exist and if an app is a heavy consumer of vCores or Memory then you should isolate it in its own app service plan. Using the quota option from the app service plan it will show how much in total is used and then separately from each app service you can see their storage quota used as well. Now for CPU or Memory it gets a bit complicated as no straightforward way to see this all-in-one place.
I'm running a function app in consumption mode and would like to know if all the assemblies packaged in an app are stored on an HDD or SSD? I'm seeing bad cold start times. If HDDs are being used, is there a way to upgrade to SSDs (without having to upgrade to a Premium plan)?
Azure Function is based on the App Service Sandbox. If you deploy it to azure, it will be deployed to a physical machine for storage and processing according to the virtual concept of service plan. If you use a Service Plan that Azure does not promise to give SSD durable storage, then your files will not be durable stored on the SSD. (Even if there is an SSD disk on the physical machine assigned to you, it will definitely not give you the SSD for durable storage.)
For example, your function app is based on a service plan, which requires Azure to allocate two virtual machines. Under these circumstances, no matter whether the actual physical machine has SSD or not, as long as the service plan you choose does not support SSD durable storage, then azure will not allocate your compiled files to the SSD disk for you to durable store(such as dll).
If you want to use SSDs for persistent storage, then you should choose a service plan that promises to provide persistent storage SSDs. Because the azure function is deployed to the machine based on the service plan.
I have a App Service plan consisting of 2 S3 instances (each is 4 cores and 7 GB RAM). In the portal on the service plan blade I see this:
What exactly do these percentages mean? Is it 44.41% of 7 + 7 GB RAM? The plan hosts 7 web apps and I get an alert that one of the app exceeds 85% memory limit. How is that possible? 85% of what? Does that mean each app gets 7/7 = 1GB on each instance? If I open a specific web app blade I see the following:
Is it ~1GB on each of 2 instances or total? How do I understand memory consumption by each web app per service plan instance?
Is there any good tutorial on these metrics as the official documentation is not very clear?
For the first graph,The memory percentage showing is indeed the memory used by the resources in the app service plan . So its actually 44.41% of 7+7 Gb . If the resources are using 85% of it then it will by default create a alert to user . So in that case ,upgrade the instances to allocate more memory and cores or scaling up the instances so that the performance of the app is increased and user won't receive the alert.
The other one is DataIn is the average incoming bandwidth used across all instances of the plan and for the Memory Working Set is referred as the maximum physical memory of the RAM used for a process performed by instances .
Please refer more to this document for monitoring app service.
I would like to create containers for each virtual machine, then deploy them.
As I known deploy is not free.
Is it free to create container in Azure?
For Azure Storage, you only pay for consumption, measured in GB/month (e.g. less than a nickel/month per GB). Containers are essentially free, since they take up virtually zero data.
The pricing of Azure storage is based on consumption or how much you use. More information of the pricing can be found on the Azure website.
Pricing also varies by region and by type of storage you provision.
