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. Julia lang support for Azure Functions

    With Julia lang reaching v1.0 last year, it is emerging as a force in machine learning and other scientific computing applications,

    https://juliacomputing.com/case-studies/

    In particular, BlackRock's Aladdin, Conning Asset Management, and Aviva are all using Julia for financial risk modeling and I see a great opportunity for Julia to impact finance among other things. I'd love to be able to use Julia in Azure Functions for my fintech startup.

  2. 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.

  3. 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

  4. Support for native Rust Azure Functions

    As of February 2019, Azure Functions support native .NET, JavaScript and Python.

    Could we please have native support to run Azure Functions written in Rust? To host Rust functions currently we have to pay for a Linux App Service plan and embed our functions within a Docker container. This is expensive just to run a few microservices written in Rust.

    Peter Huene has an excellent project for anyone interest in writing Azure Functions in Rust....

  5. Access the management console for Azure Functions in an App Service Environment deployed via ILB

    As it stands, Azure Functions and Web Jobs deployed in an intranet-based App Service Environment cannot be managed via the Azure portal unless the user is connected to the internal network or VPN. It appears that the advanced management console code is deployed into the App Service Environment for these services,, as the SCM host name is provisioned on the custom domain. This makes remote management difficult especially for enterprise customers.

  6. Profiler support for .Net Core Azure Functions

    I would like to be able to profile a .Net Core Azure Function such that I can see a breakdown of how long each method invocation takes within the call stack so I can optimise any bottlenecks.

  7. 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.

  8. 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…

  9. Address Azure Functions Resiliency Weakness to Azure Service DNS issues

    Azure DNS issue R50C-5RZ caused multiple core Azure function triggers to fail across our subscriptions due to loss of access to Storage Accounts.

    The DNS issue made all our storage accounts temporarily unresolvable by DNS and because of the tight coupling with Azure functions, function triggers failed due to the inability to resolve storage account urls but did not recover when the DNS issue was corrected.

    There were some Socketexception / 'remote host not found' errors logged in App insights but seemed to be no way to know that the trigger was in a failed state (unless a build up…

    This is an awesome idea!
    We’re very unlikely to be able to reduce our dependency on DNS, but we can generally handle failing triggers more gracefully.

    “Handle temporary loss of a storage account without requiring a manual restart” is a scenario we’re targeting.

    Keep the feedback coming!

  10. 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.

  12. Support for Azure Managed Service Identities in EventHub (and other) triggers

    In Event Hub, I can add my Function App's MSI as a data reader, but in the function I cannot use trigger bindings to read from the queue without using a SecureAccess Key. We are trying to go password free wherever possible, and Azure has been promoting this course of action, so why do we need secret keys for reading from the queue? It then forces us to create and share a secret key for partner teams to read from our queue, rather than just permissioning them in Event Hub.

  13. Move from Python 3.6 to Python 3.7 for Azure Functions v2

    On python.org, the release notes for the latest 3.6.8 release state:

    Python 3.6.8 is planned to be the last bugfix release for 3.6.x. Following the release of 3.6.8, we plan to provide security fixes for Python 3.6 as needed through 2021, five years following its initial release.

    It seems weird to choose a Python version branch for Azure Functions that will not receive any more bugfix releases ever.

    Can the Python version be bumped to 3.7 to fix that?

    Thanks,

    Tobias Weisserth

  14. 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.

  15. 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.

  16. Allow moving from AppServicePlan to Consumption plan (in Azure portal)

    It should be easy to move between hosting plans for Azure functions so we can change this based on the current needs. At the moment, I would like to move away from app service plan for a lot of functions (use consumption plan instead), but in the future, high continous demand might move some back to an app service plan. Changing between the to modes should be as easy as scaling out on an app service plan

    I have read somewhere that there is a problem if a function was created as an app service plan because of missing storage.…

  17. 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.

  18. 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.

    Function Apps that are VNET integrated require a dedicated subnet. The Subnet that is allocated does not currently support UDR. Without the UDR Support we cant route this traffic through a fIrewall appliance for on-premise connectivity.

  20. Add settings to change local logs verbosity/level

    When running functions locally, on every call to a function I am bombarded with logs, can we have an options on the cli, or in local.settings.json to change the logs verbosity/level (debug/info/warning/error...) so it will be easier to debug and work with functions?
