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. Golang support for Azure Functions

    C# and other environments are already supported; it would be nice if Go / Golang was one of them. I'd love to handle web requests using Golang + Azure Functions.

    It could provide the "HTTP Requests" via the stdin, while the "HTTP Response" can be given via the stdout. (or whatever those two are called on Windows ;-) )

    I’ve gotten a few questions about this item recently, so I just wanted to give a more detailed status. We still have this on the backlog; it hasn’t been forgotten. But we don’t have a clear timeline for when we would get to it right now. The “unplanned” status just means that it can’t be tied to a timeline, but we do think this is a valid request that we would like to have in the product.

  3. 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.

  4. Add max calls/per day|hour|minute configuration for throttling

    Now- any light ddos attack that Azure will not recognize- will affect me and my account. If I know that my service shouldn't receive more than 10000 calls per day, but I can't setup limits on incoming requests.

    "Daily Usage Quota (GB-Sec)"- not bad idea, but it's something internal and synthetic for me. Call/per day- is much more native metrics for users.

    Moving this work item to unplanned, as it is clear that this request is no for a global throughput limit.

    We do now offer the ability to limit your maximum instances in the Premium plan, which will allow you to avoid swamping downstream resources. https://docs.microsoft.com/en-us/azure/azure-functions/functions-premium-plan#plan-and-sku-settings

    We prioritized that above a max call per X limit, because our only control to limit throughput is to outright deny some number of requests above a threshold.

  6. SQL Azure trigger support

    Azure functions are great, but a lot of application logic is driven by data in SQL Azure DBs. It would be great to have a trigger based on a SQL Azure row data.

  7. Handle Storage Queue/Service Bus messages in batches

    I want to be able to handle multiple messages per function call - we are using a third-party web service which works much more efficiently if the messages are passed to it in batches. I know we could use a timer to trigger the function and grab messages from the queue ourselves but if we do that the function won't scale out automatically.

  9. Allow websockets ( SignalR ) feature in azure serverless using Functions

  10. Zip deploy Functions with app level credentials instead of user credentials

    Right now you if you want to use zip deploy you need to use user credentials, those can be used to deploy any function anywhere in your tenant. Not really the best way to handle DTAP. Would be nice if you could also the app level credentials which do work for the other deployment options.

  12. 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....

  14. Add support for Kafka Streams from HD Insight

    Azure Functions should be able to be triggered from Apache Kafka. The triggered function should be able to be configured for a specific consumer group, with options to explicitly commit the consumer's offset.

    Ideally Kafka Streams could be supported, with special support for local storage of KTables.

  15. The dynamic tier should never run out of sockets

    If you have too many connections, you can get SocketExceptions. The dynamic tier was meant to stop us from having to think about server instances, but with a connection limit, the dynamic tier is useless and we are back to the standard service plans.

    This is an awesome idea, and we’re exploring a few options to make it a reality.
    However, the 600 connection limit per instance should be enough for most applications if you’re reusing or closing connections. If you truly need 600 open connections you are likely to run into the 10 minute timeout per execution.
    Even after we add this you will still need to be mindful of your connection management.

  17. Support Service Bus trigger with use of SAS token

    In our company we are using Service Bus with a framework that deals out the SAS tokens to queues. These tokens are living for few days only and concern hierarchical queues (eg. queue name could be productA/event-type-B/subtypeC) and only Listen policy.
    This would mean that listening on a different level then root level of namespace would be needed.
    Best if also the whole connection to SB described by this token would be separate object from the Function, so we could modify it (by altering with new SAS token/whole connection string) without modifying the Function code (as API Connections in Logic…

  18. 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…

  19. Add Auth0 to list of identity providers and allow custom URL in 'URL Authorization Rules

    [This is more an AppService issue but there's not forum for that.]

    It's important to me to have the ability to use a custom authentication UI and Auth0 provide this and their own database for user storage. Otherwise I have to roll my own. My users do not have any existing accounts (including email) and so need a simple username / password experience (as horrible this might be for most of us)

    A reasonable list of providers is available but adding Auth0 will open the possibilities up. Auth0 is not only excellent but acts as a proxy to a very…

  20. Proxies should support backend.request.body expressions in requestOverrides

    Would be great to be able to create or change the request BODY dutring request overrides processing like it is possible for headers and the method already. Expressions could override parts of the body, create a body when e.g. overriding a GET to a POST or update body parts / subparts. Even deletion of body or body parts would be usable...
