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?

  2. 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.

  3. 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.

  4. 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.

  5. openId connect plugin / guidance

    In MVC, we have Microsoft OpenId Connect / Owin to secure the application using Hybrid flow with a Single Page Application on the front end.

    The request is to have capabilities to move from MVC SPA (self hosted VM) to Serverless (Azure blob + Azure function as backend) to do Hybrid flow authentication.

  6. 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…

  7. Add ability to restrict deployment from dev environments

    I recently created a new function app in our team's tenant to handle some custom monitoring. Now that I'm done prototyping it and have it in a workable state, I've created an Azure DevOps build and release to handle publishing the app.

    I need to do this, rather than simply use the CD from git branch option, because I'm using Typescript (currently unsupported), and need to install both node_modules and extensions for the app (because the app won't perform those steps itself based on package.json or extensions.csproj)

    While the pipeline now works, I can't find a way to lock down…

  8. Manage Function Proxies using the Azure REST API

    Similar to how functions work, it would be useful if we can programmatically manage Proxies within Functions using the Azure REST API.

  9. certificate

    Can Azure Functions support SSL certificate for consumption plan?
    I found on https://docs.microsoft.com/en-us/azure/azure-functions/scripts/functions-cli-configure-ssl-certificate that "To bind an SSL certificate, your function app must be created in an App Service plan and not in a consumption plan."

  11. Add C++ support for Azure Functions

    Allow C++ binaries to contains Azure Functions. It could be done by invoking the main in an executable, or a DLL with a specific export method with predefined signature.

    C++ allows to control memory usage and allow users to be incredibly fast when used properly. In an environment where scaling is needed, squeezing a few seconds of CPU or lowering a few KB of RAM can translate to hundreds or thousands of dollars in savings.

    If memory leaks are a concern, putting aside the fact that C# code can also leak, you could create fail safes for Azure Functions. A…

  12. 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/

  13. Enable triggering of Azure functions based on an event in RabbitMQ

    Hello, we are having a scenario where we should be able to trigger a function when a message is added to RabbitMQ. This would be really helpful in using Azure functions to integrate with other Message queuing platforms that support AMQP protocol.

  14. Set environment variable override for AuthorizationLevel.Function key

    When running within the Azure Functions Runtime inside of a Docker container, we can't use AuthorizationLevel.Function as there is no way to retrieve the key from the runtime. It'd be great if we could directly set a function key in our compose.yml as an environment variable. For deployment, we just leave the environment variable blank and the App Service can set the keys.

  15. EventHub Trigger filtering based on properties

    It would be great to be able to provide a filtering expression in the binding of an eventHubTrigger. Using this I could configure my function to only be invoked for certain events that match the filter. For example, I store a property called "eventType" in the application properties of each event. My function is potentially only interested in events of one or more specific types. Currently I code this logic into the function, which works fine. However, it counts as an unnecessary invocation and increases the cost. Ideally the filtering would take place in the host and not incur a…

    Unsure on this one but marking as unplanned. The filtering would also have to happen at the client to preserve ordering. However even if we did the filtering before the execution it’s still consuming compute so I don’t think it makes sense for it to be “free.” Just because the trigger is doing filtering before execution wouldn’t necessarily negate the price aspect. And since filtering often has some custom parsing / decoding / conditions it’s almost better to do it in code.

  16. 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.

  17. 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.

  19. Add support to Open Tracing/Zipkin

    Opentracing (http://opentracing.io/) is a popular standard for tracing correlated requests across many different services communicating via RPC. It contains implementations on several different platforms and various tools (zipkin being one of the most popular ones). The standard can be easily extended over HTTP using dedicated headers from client/server side. It would be great if Azure functions would be able to provide more or less transparent support for it.

  20. Add support for hybrid connections to Consumption Plan

    Can we add Hybrid Connections to functions running in Consumption Plans

    I'm aware of the idea ...
    https://feedback.azure.com/forums/355860-azure-functions/suggestions/14807298-should-support-hybrid-connections

    But this is for App Service Plans, and only mentions Consumption Plan in the response.
