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. Support for session-enabled Azure Service Bus queues/subscriptions

    Currently the queue/subscription trigger only works with queues and subscriptions that does not use sessions (RequiresSession = false). It would be very useful if the runtime would detect that sessions are enabled and adapt accordingly. As far as I can see, the actual function code would not even have to be aware.

  2. OpenAPI from function app v2

    Function App v1. could create an OpenAPI (swagger) file. After the change to v2. in the portal creating an OpenAPI file is "not supportet".

    Please reinstate this feature

  3. Function App Service support for Azure B2C

    If I build a web app using Azure B2C for authentication, I'd like to use it as the authentication provider for Azure Functions too. Although I can set up the same providers, using B2C would be cleaner and enable me to support users with local logins (traditional username and password) too.

  4. Retrieve function app keys from ARM template

    Make it possible to set/retrieve function app keys via ARM templates.
    This will make it easier to store it in the settings of an other service while rolling out an environment.

  5. Add Open Connection count to Function App

    We are using a Function App for consuming events from an EventHub, to process each event we make 4-5 REST calls and we find that our S3 instances run out of outbound connections resulting in ETIMEDOUT errors. We opened a support case and we are troubleshooting. However to make it easier to debug and to allow us to put alerts in place it would be nice to have the number of open connections available through the Portal and be able to attach alerts..

    Update: Still planned!
    -
    This is something that we have enabled internally, and are in the planning process of highlighting TCP connections for customers in the “Diagnose and Solve problems” tab. However, we do not have an ETA yet.

    Thanks for the feedback!

  6. Add support for Open API (Swagger 3)

    Azure Functions currently supports Open API (Swagger 2) (https://azure.microsoft.com/en-in/updates/announcing-azure-functions-open-api-swagger-support-preview/).

    Now that Open API 3 has been released, it would be helpful if the latest standard could also be supported

  7. Allow moving Function from Consumption to Service Plan

    Currently if you deploy your function on a consumption plan there is no way to move it to an existing Service Plan like any other App Service.
    You would need to delete the existing one and redeploy it..

    Quick update here – with the announcement of the premium plan we do support moving from consumption to a premium plan. Today this may not work for all consumption apps in a region only because some consumption apps may exist in a “webspace” that doesn’t yet have premium turned on. That said we have CLI commands rolling out in the next few weeks to make this seamless.

    Moving to app service plan is a bit trickier as the actual code often lives in a different place on an app service plan (app service local storage) than where consumption needs them (azure storage files) – so moving may not work and currently don’t have any immediate plans to do like “code migration” in addition to changing plans.

    You can see a sample of moving plans between apps in this sample here as well: https://github.com/Azure-Samples/functions-csharp-premium-scaler

  8. Don't 'hardcode' the storage account connection string for the storage account that backs azure functions

    Currently each Function App has an application setting string "WEBSITE_CONTENTAZUREFILECONNECTIONSTRING"which is a fixed (=hardcoded) connection string. This breaks when performing key rotation on the connection string and is opaque to diagnose since that setting is automatically setup by the portal UI/wizard.

    Can you instead just store the subscription ID and storage account name and then fetch the latest connection string for the storage account using the management API? This will make sure that the function app survives storage account key rotations

  11. Functions Summary/Status on Function App dashboard/home

    It would be helpful to have a dashboard on the Function App home page to display summary/status data about all the Functions in the Function App. For example I currently have to go to each Function individually and click Monitor to see Recent Success or Error Count or to the Manage tab to see if a Function is Enabled.

    The current "The faster way to functions" getting started content is really only relevant for new users.

  12. Support authentication for Azure Function Core Tools

    Azure Functions has been great, especially the ability to run the Core Tools locally. However, there are often scenarios where you return data depending on the currently authenticated user. This appears to be supported in Azure Functions in Azure now but there are no options within the Core Tools. This would be hugely useful for local development.

  14. Enhance Azure Durable Function performance by enabling use of Redis as a backend store

    Durable functions are great, however they do run into some performance bottlenecks when working with fan out for really large numbers of tasks, reduce the overhead caused by Azure Storage reads and writes by enabling an option to use distributed in memory storage such as Azure Redis to implement the required backend queues & stores.

  15. Want to be able to enable Application Insights via the azure cli when creating a function without having to rely on an ARM template.

    I want to be able to enable Application Insights via the azure cli when creating a function without having to rely on an ARM template. It seems like all you should have to do is have an option to say enable it and an option to state location information.

  16. Azure auth populate request.user

    When using the azure auth over functions, specifically those that take a http trigger, it would be great if it would populate the request.user in a similar way you can do using node.js and passport (https://github.com/Azure-Samples/active-directory-b2c-javascript-nodejs-webapi/blob/master/index.js) rather than just providing some headers.

    This would make it much easier to work with authenticated users and interact with their information

  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. Select existing Application Insights ressource on Azure Functions creation

    It is a real pain to create a new function using an existing App Insights ressource:
    1. Create function with Application Insights enabled
    2. Wait for the function to be created
    3. Go to Azure functions -> platform settings -> all settings -> application insights
    4. Press "change" to bind the function to an existing App Insights resssource
    5. Go to App Insights
    6. Locate the newly created default App Insights ressource for the function and delete it

  20. At-a-glance failure monitoring in UI

    Would be great to see the current health of all functions in a single view. Black for successful, Orange for functions with warnings and Red for functions with errors on last execution.

    Also, last x runs in a color-coded graph (same as last x builds in VSTS) would be brilliant so we can quickly visualise the health of our function apps.
