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.

  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 ;-) )

  2. Enable custom 3rd party authentication providers

    Outside of out of the box providers like facebook and google, provide samples and guidance on how to authenticate with others like LinkedIn.

    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. 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....

  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. Allow running headless Chrome (or other browser) in Function apps or Web apps

    Basically it's this:
    https://cloud.google.com/blog/products/gcp/introducing-headless-chrome-support-in-cloud-functions-and-app-engine

    Now obviously Google has a bit of an advantage here what with Chrome being their own tech but there are so many blogs out there with people talking about complicated Docker solutions just to run headless Chrome in the cloud.

    It would be great if we could get a solution where we could run Puppeteer in much the same way, or allow web apps to run Chrome without having to be inside Docker and we could manage a pool of Chromes without having to manage Docker as well.

    Headless Chrome requires some libraries to be installed that aren’t available in the containers we use in Linux consumption. You can, however, run your function app in a Docker container with the libraries installed. Custom containers are currently supported in the Premium and App Service plans. Take a look at this example from a community member of a Dockerfile with the dependencies: https://github.com/estruyf/azure-function-node-puppeteer/blob/master/Dockerfile

  8. 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.

  12. 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.

  14. 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.

  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.

  16. 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.

  17. 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…

  18. 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…

  19. Azure Function - Event Grid Output Binding

    Presently there is only an Azure Service Bus output binding for Azure Functions, there is nothing to pass the output on to another Event Grid Endpoint.

    This would be very useful.

    Kind Regards

  20. Folders for organizing Functions and a TreeView Function List in the Portal

    Already I have a Functions App that is growing larger than works well in the existing Portal interface.

    I would like to suggest adding support for folders (similar to solution folders in Visual Studio) that allow one to organize functions. And then a TreeView for the Function list in the Portal.

    For example I have several processed in my Function App. Each process may have one or more steps that are usually individual Functions. It would be great to put all the related Functions together in a folder.
