I have a need to read a dedicated mailbox and read new messages and its attachment. The preferred way to do this now, seems to be with the newer Graph API. This requires setting up an azure application. Ok, so forgive the newbie question, but how can I get an idea of what an expected monthly cost will be?
Taking for granted that you already have an Office 365 (Exchange Online) subscription and Azure AD tenant, neither AAD application registration nor Graph API requests wouldn't cost you anything extra.
As for the application itself, the cost will depend on the Azure service you'll choose it to deploy to. You've used the "azure-functions" tag in your question, so I assume that's what you are going to use. Well, it's quite hard to estimate an Azure function cost before actually running it (do you know the resource consumption of a piece of software which doesn't exist yet?), so I'll suggest you proceed this way:
Create a new Function App, be sure to select "Consumption Plan" as its hosting plan;
Go to your app -> Function app settings and set the "Daily Usage Quota (GB-Sec)" as 12900. This way you'll ensure your app will not exceed the 400,000 GB-s execution time, included for free in your subscription;
Deploy your application and have fun with the Graph API for free;
Enable Application Insights integration for your function app and monitor Execution Count and Function Execution Units metrics to have an idea of what's your function approximate consumption is.
P.S.: Please have in mind that other Azure resources you would utilize besides your function itself (storage account, application insights, outbound traffic, etc.) could result in some charges, though I doubt they will exceed a couple of bucks monthly if you don't store terabytes of data as a part of your app logic.

When hosting an Azure Function in an App Service Plan, are there any significant differences compared with using an App Service (EDIT: for a restful API) associated with the same App Service Plan? I assume the only difference is that the Function offers additional out of the box triggers. Any differences I'm missing that would lead to preferring one over the other?
I'd also like to confirm that hosting Azure Functions in an App Service Plan can actually limit scalability if scaling is not configured on the App Service Plan. As I understand it, Functions automatically scale as needed when using Consumption or Premium hosting without additional configuration.

Well, an Azure Function is a different beast than an App Service. An Azure function is triggered by an external event or a timer. It then executes the code of the function. When hosted on a consumption plan this execution is allowed to run for 5 or 10 minutes max. When you need a longer execution time you need to run it on an App Service Plan.
An App Service can host any app you've created. Like a website (that runs continuously and doesn't need to be triggered before it starts doing something) or an api for example.
I'd also like to confirm that hosting Azure Functions in an App Service Plan can actually limit scalability if scaling is not configured on the App Service Plan. As I understand it, Functions automatically scale as needed when using Consumption or Premium hosting without additional configuration.
Correct, when hosting Azure Functions in an App Service Plan you are responsible for making sure the app service is scaled to allow the function to perform well under load. Thats why the consumption plan is designed to handle this so the developer can focus on the functionality and does not need to worry about the infrastructure.
So, for integration scenario's azure functions are a very natural fit. For web sites an App Service might be the best solution.
To address your comment:
I should have mentioned that this question was in the context of hosting a restful API and not a UI application. In this scenario, I'm not seeing much difference between a Function and App Service, but please correct me if I'm missing something
A couple of things: For one, there is a certain sweet spot. If traffic is heavy enough a consumption plan based azure function might be more costly than having a dedicated app service plan. That depends of course on a lot of factors (CPU usage, request duration etc.). Also, you won't be able to use things like Asp.Net Core Middleware out of the box.
Finally, I'd argue that if your api is becoming large enough managing a single asp.net core solution may be easier than having to manage a lot of azure functions with small functions or one azure function project with lots and lots of functions, but hey, that's just my opinion (haven't actually dealt with it to be honest)
Some resources to consider:
https://www.taztopia.com/single-post/2019/07/28/azure-function-vs-web-app-aka-serverless-vs-paas
https://dasith.me/2018/01/20/using-azure-functions-httptrigger-as-web-api/
The main difference is in how you pay for it:
Azure Functions Consumption plan you pay per execution
Azure Functions in an App Service (dedicated plan) you pay for the allocated hardware per minute.
You also have control of which VNET your functions run in when you use an app service plan. You may have security requirements that make this important.
You are correct that if you run it in an app service that is not configured to scale, then throughput will be limited by the allocated hardware.
For details see: https://learn.microsoft.com/en-us/azure/azure-functions/functions-scale
If you are having limited and predictable workload then deploy az function in AppService plan with supports VNET integration for private compute otherwise go for Premium plan which will provide autoscaling capability of your compute environment.
I have a .NET Core application currently running as an Azure App Service, and I need it to do a lot of 'work' only about a few times a day. In order to save on the hourly billing, this is the solution I developed:
Using a runbook (Azure Automation): scale the App Service Plan to the 'Free' tier at 7:00 PM
Using a runbook (Azure Automation): scale the App Service Plan back up to the premium tier at 8:00 AM
Hard-code my .NET Core application to ensure it only does the heavy 'work' between 8:00 AM and 7:00 PM
This is fine as it saves me a significant portion of cost, as I'm only paying for the hours in which the App Service Plan is scaled up to the premium tier. However it is definitely not ideal.
My question is - what design pattern should I implement in order to accomplish what I'm trying to do? I need a lot of compute resources but only for a few hours out of the day. I know AWS has 'spot' instances that you can configure - is there a similar mechanism in Azure?
Ideally I could implement a solution that involves me only paying for those heavy compute resources when I actually need it (e.g.: a few times a day, while the sun is up)
Thank you for any insight and help!
EDIT in regards to the type of computation, my summary is essentially a few ML.NET trainers running in parallel with some moderate Elasticsearch document writing
It is pretty tough to answer this with the whole description of your workload being a "lot" of "heavy compute".
If you can put your "compute" into Azure Functions, going serverless with a consumption plan will probably be the nicest solution. However, individual function executions have a given timeout, so you need to see if your app fits the bill.
As an alternative, you can put your application into an Azure Container Instance, and spin that up on demand.
If you have REALLY high workload, you can use Azure Batch. If your current workload can be done on an AppService plan, this may be "overkill".
The equivalent to AWS spot instances is called Azure Spot Virtual Machines. You can also use them with Azure Batch.
Yes, you can switch to Serverless. Host front end on Storage Accounts and back end move to Azure Functions (Consumption Plan).
PS: If it's a long running processing, it may not be the best solution unless you use Durable Functions.
I've had to switch from the Shared tier to Basic, to avail of SSL support and with that I knew there would be a price hike. But for me it has gone up exponentially - this is going to cost me an extra £50+/month.
I have turned off the "Always On" setting and from analytics I can see that there is no traffic between 11pm and 5am most nights yet im averaging a bill of 22 hours per night service for the last 23 days...that's effectively "Always On".
Anyone know if I need to tweak something else to reduce the costs? Is there a setting that determines how long before the service goes to sleep?
The cost that you pay for the instances in App Service runs all the time, traffic does not matter.
If you have 1 instance in the plan, you pay for that 1 instance all the time. Always On just prevents an app from idling. It won't reduce billing if you turn it off.
At minimum on Basic tier and up you pay for 1 instance + outbound data traffic.
As juunas stated that Always On could not help you to save the cost, it just be put to sleep and free up resources for other web apps on the same service plan.
Anyone know if I need to tweak something else to reduce the costs? Is there a setting that determines how long before the service goes to sleep?
Even if you stop your app, the App Service plan charges still apply, and the service plan could not be stopped. For a workaround, you could schedule a task and invoke Azure Management SDK to switch the App Service Plan (Shared, Basic).
Use Microsoft.WindowsAzure.Management.WebSites with the authentication using a management certificate. Here is the core code, you could refer to it:
Change pricing tier from Basic to Shared
using (WebSiteManagementClient webappClient = new WebSiteManagementClient(credential))
{
//you could leverage webappClient.WebSpaces.List() to retrieve your webspace
//the format of your web space would be: "{resource-group-name}-{location-of-your-appserviceplan}webspace"
var webSpace="{your-web-space}";
webappClient.WebHostingPlans.Update(
webSpace,
"{The name of the web hosting plan}",
new Microsoft.WindowsAzure.Management.WebSites.Models.WebHostingPlanUpdateParameters()
{
NumberOfWorkers = 1,
SKU = Microsoft.WindowsAzure.Management.WebSites.Models.SkuOptions.Shared
});
}
Note: After change the pricing tier to Shared, your configured SSL certificates would be reserved and until you change it back to Basic, you could retrieve and modify it and it could take effort. Moreover, if you scale out your app into multiple instances, you need to specify the property NumberOfWorkers when you changing pricing tier to Basic. For more detailed steps, you could refer to this similar issue.
I have an Azure Cloud Service published at Microsoft and it's draining all my credit!
Payment
Pay as you go
Service resource
Minimal resource, 1 SMALL web role and 1 SMALL worker role.
I knew Azure wasn't cheap, but this is just too much. Currently my monthly cost is just under 80 USD. The only person that use this service is me, noone else, and I barely use it. So the cost is just for the upkeep.
Is this normal?
70 bucks a month!?
How much does it cost for YOU?
What Microsoft support told me
I am afraid the Cloud Services has a fixed price, and I am not aware
how it could be lowered. Maybe you want to check on how the service
itself could be tweaked to get it working as per your needs. You may
want to go through the Community Forum for that.
Community = Stackoverflow, so here I am!
If I look at my Azure subscription page I can see that it's the:
CALCULATING HOURS - Europe, Western
That is taking all my hard earned money. My service also uses SQL, storage and cache but, if I understand it correctly, these are not the cause for my expensive bill.
Before I leave you to it I just want to say that I can't use a simple web app because of my requirements. I know web apps are super cheap, but in this case I must use a cloud service..
Thank you
Update
I found out I was using A1 (small) and not A0 (extra small). The instance type for a cloudservice can be set in the servicedefinition file.
It's sad that not even Microsoft themselves could inform me about this.
Web and worker roles are like dedicated VMs if they are on, they will cost you money.
You can do one of two things
1) Stop the machines when no one is using them ( say in the off business hours). I am not sure if this is possible to do or not in your case. But if it is possible, you can run a small script to start/ stop the roles. You can even do so via apps on your phone. For example - https://itunes.apple.com/us/app/azure-management/id826446897?mt=8
2) Move to Azure Web Apps and Azure Web Jobs - Both these services are "multi-tenant" and cost much less and in fact offer a free tier. If and when you need to scale, you can always scale as your need
Hope this helps
I'm considering to join the Windows Azure Platform Introductory Special, but I'm a little bit afraid of losing money with it. I don't wanna develop any fancy large scale application, I want to join just to learn Azure and do my experiments, what should I be afraid of?
In the transference, it says: "Data Transfers (per region)", what does that mean?
Can I put limits to stop the app if it goes over this plan in order to avoid get charged?
Can it be "pre pay" instead "bill pay"?
Would it be enough for a blog?
Any experiencie so far?
Kind regards.
As ligget pointed out, Azure isn't cost affect as a host for an application that can be easily deployed to a traditional shared hosting provider. Azure's target market are those that want dedicated resources without the need to micro-manage the infrasture and the capability to easily scale up/down based on demand.
That said, here's the answers to the questions you posted:
Data Transfers are based on bandwidth in and out of the hosting data center. bandwidth for communication occuring within components (SQL Azure, Windows Azure, Azure Storage, etc...) in the same datacenter are not billable.
Your usage is not currently capped when the free quotas are used up. However, you will recieved warning emails when those items approach their usage threadsholds.
There is the option to pay your subscription using a PO, but the minimum threshold for most of these operations is $500/month. So as a hobbyist, its unlikely you're wanting that route.
The introductory special does not provide enough resources for hosting a 24x7 personal blog. That level includes only 25hrs of compute resources. Each hour a single instance of your application is deployed will count against this, even if the application received no traffic. Think of it like renting office space. You still pay rent on the office even if there are no customers there.
All this said, there's still much to be learned with the introductory special. The azure development tools allows you to work with Windows Azure and Azure storage locally and get a feel for how they work. The introductory special then lets you deploy those solutions so you can see what works and what doesn't (not everything that works locally works hosted).
I would recommend you host your blog somewhere else - it's a waste of resources running it on Azure and you'll find much cheaper options. A recently introduced extra small instance would be a better choice in this case, but AFAIK it is charged separately as of now, e.g. even when you have an MSDN subscription those extra small instance hours do not count towards free Azure hours that come with the subscription.
There is no pre-pay option I know of and it's not possible to stop the app automatically. It'll be running until the deployment is deleted (beware! even if suspended/stopped the deployment will continue to accrue charges). I believe you will be sent a notification shortly before reaching your free hours threshold.
Be aware that when launching more than 1 instance you are charged for every hour of every instance combined. This can happen for example when you have more than one role in your Azure project (1 web role + 1 worker role - a separate instance will be started for each role).
Data trasfer means your entire data trasfer: blobs/Table storage/queues (transfers between your hosted service and storage account inside the same data center are free) + whatever data is transfered in/out of your hosted application, e.g. when somebody visits your pages. When you create storage accounts and hosted services in Azure you will specify a region that will be hosting your account/app - hosting in Asia is slightly more expensive than in Europe/U.S.
Your best bet would be to contact Microsoft with these questions.
