Azure Functions

Azure Functions is an event driven, compute-on-demand experience that extends the existing Azure application platform with capabilities to implement code triggered by events occurring in other Azure services, SaaS products, and on-premises systems. With Azure Functions, your applications scale based on demand and you pay only for the resources you consume. Azure Functions provides an intuitive, browser-based user interface allowing you to create scheduled or triggered pieces of code implemented in a variety of programming languages.

How can we improve Microsoft Azure Functions?

  1. http trigger for runtime

    Hi,

    Could you please add HTTP trigger for on premise (runtime) environments?

  2. VS 2017 Azure function for powershell.

    Currently I don't see any powershell support within VS 2017 for developing azure function. Any idea when this would occur?

  3. Please support calls to System.Drawing.Bitmap ?

    Hello Team,
    Azure function v2 engine does not support calls to System.Drawing.Bitmap class. I understand that this limitation has been documented under https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox

    I find System.Drawing.Bitmap very useful when it comes to reading image files. Our current product (on .NET Framework) relies on System.Drawing for image processing and works very well. However we are unable to port to Azure because of the sandbox restrictions.

    I request the team to consider this support in future versions of the runtime.

  4. Provide memory usage data in context object

    It would be great if we could manage memory in realtime in our code. Please provide a method to check memory usage in the context object so that we can take mitigating steps in our code if there is not enough memory.

  5. SMTP Triggers

    Functions are great for building HTTP-based Apis. Our SMS-api supports both HTTP(S) and SMTP(Mail 2 SMS).

    In order to use Functions, we would need to be able to bind one or more email domains to it and use email as triggers

  6. When publishing through Visual Studio, create the storage account on the same region as the function

    I deployed my function through Visual Studio, creating a new one on an existing resource group.

    I chose to create a new Storage Account as well.

    I chose eastus2 as the region for my function. But after the deployment succeeded, I noticed that the region for the storage I created during the functions deployment was set for Central US.

    I'd like the created storage to be on the same region of the function. I double checked and there's no way to select a region for the storage you create in deployment time.

  7. Share RUs with a Serverless Function

    A popular pattern is to build a REST API using serverless Function with Http trigger, backed by Cosmos DB. Serverless is a very popular paradigm, and Cosmos is the best cloud database, so it's no wonder that customers are interested in this combination. However, the problem in this scenario is the cold start of the serverless Function, which negates the low-latency benefits of CosmosDB provisioning.

    It would be great to allow sharing the RUs provisioned for Cosmos DB collection with serverless functions running against the same collection. Let the Function execution consume some extra RUs, depending on the complexity of…

  8. local settings json

    Add the ability to create a template local.settings.json file in the dev tooling for VSCode and Visual Studio. Since local.settings is git-ignored by default, when a developer clones down a repo they often have to re-create a local.settings.json file. To do this it involves simply creating a bare json file and hand-coding the right schema/values. It would improve developer productivity to add a "New local settings file..." option to the dev tooling which creates the same skeleton file a dev is given in a new function project.

  9. Geo-availability integration a la CosmosDB for Consumption Plan

    For Functions in a Consumption Plan, it's a bit arduous to get them to be geo-distributed (have to set up deployment to all the various regions you want to support, add APIM/Traffic Manager to handle). It would be _super_ awesome if Functions had a setup like CosmosDB where you deployed them once, then "lit up" the geos you want the code replicated to. Then, not too much different than the request in #214 , an "invisible" Traffic Manager service could be provided on the endpoint for the Function to hit the nearest geo to the end user.

  10. Support for "delete" DocumentDB Change Feed Trigger

    Currently there is support for DocumentDB Change Feeds which only trigger for Insert and Update changes, however there is no way of picking up Delete changes to a collection

    My use case has a real-time web application which relies on these change triggers to update the User Interface through Web Sockets that a change to a document/collection has taken place, at the moment I am having to implement this manually through a delete API call but that does not solve the problem if a document is manually deleted at source (for example).

    A Delete of a document (IMHumbleO) is as…

  11. Scala support for Azure Functions

    The Java worker for Functions allows Scala to be exectured in Functions relatively easily. It would be great to see Microsoft support Scala as they do Java with MSFT endorced build and deploy practices.

    See post here seeing how easy it is to deploy manually https://monteledwards.com/2018/10/07/deploying-scala-code-on-azure-functions/

  12. Enable Reader Access to view Azure Functions Monitor area so that they can view the running state of that Azure Function.

    Enable Reader Access to view Azure Functions Monitor area so that they can view the running state of that Azure Function. This is important for Prod environments where most users only have only Reader access.

    This is currently unsupported, along with a large set of features that do not work in the portal with only reader view.
    There is work underway to remove this requirement, and allow us to enable UI for reader access.
    I will update this issue once we have planned that work.

    In the meantime, you can still view your logging information directly in the Application Insights instance for your Function App as a reader.

    Thanks for the feedback!

  13. Wildcard within path of blob input bindings

    I wish we could specify blob storage input bindings path that included wildcard.

    --- function.json
    {
    "type": "blob",
    "name": "faces",
    "path": "face/profile-{date}-*.png",
    "connection": "AzureWebJobsDashboard",
    "direction": "in"
    }

    Then, I hope to process these as array of Blob objects.

    ---index.js

    module.exports = function (context, myQueueItem) {
    const fileSizeList = context.bindings.faces.map(face => face.size);
    context.log(fileSizeList);
    context.done();
    };

  14. Add "Deny" option when Request is not Authenticated

    I have a function app set up as a private API that requires users to authenticate via Azure AD B2C to be able to make calls. My mobile app does the auth and then provides the Bearer token in the service calls.
    This all works but if someone happens to browse an endpoint in a browser I don't want them to be redirected to the login page as the API is only meant to be requested from within the mobile app.
    I would like an option to just deny access to the API when a request is not authorised.

  15. R

    Running R data science functions serverless is key for those organisations which have a deep investment in skills and code in this language. Azure ML Workbench has no R support so the only way to run R in Azure is with Spark Data Bricks or use a VM with R server installed.

  18. Specifying a name for a premade function

    If no function is present in a Function App, the “getting started” assistant is shown which allows adding a premade function. However, you can’t specify a name for the resulting function there, which is why you’ll end up with insignificant names such as “HTTPTriggerCSharp1” or “HTTPTriggerJS1”. It would be great if the user could optionally specify a function name in this dialog.

  19. Add an empty / drain trigger to Azure Storage Queues

    Currently there seems to be no easy way to run code as soon as a Storage Queue has been emptied. It would be great to have an empty or drain trigger to call a different Azure Function for some pre-processing of batch jobs.

  20. Visual Studio Tooling - Javascript Project Template

    C# Project Template was recently added for Visual Studio Tooling https://feedback.azure.com/forums/355860-azure-functions/suggestions/13301214-visual-studios-tooling-with-local-execution-debug , however this doesn't handle all languages - F#, Javascript/Typescript, etc.

    Hoping we can get support added for better deployment capabilities with other languages as well as source code management. Great to see the Azure Function tooling finally make it to RTM for C#!
