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.

    • 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.

        the current plan is to provide throttling controls on a per instance base, which would enable limiting the amount of executions. This can work for scenarios where downstream resources cannot be strained or even DOS attacks.

        Thanks!

      • 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.

        • 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

          • 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.

            • 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..
              We tried to run netstat from Kudu but thisis not permitted (Access Denied)

                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.

              • 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

                • 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

                    • 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.

                        This is a great request!

                        We are working to support this in the near future as a part of a larger initiative to enable several App Insights based monitoring views in the Functions UI

                          This is a great bit of functionality that we would love to support!

                          Can you update your issue, or provide a comment with what language you are developing Functions in?

                          • 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.

                              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..

                                The work to enable this on an API level should be live around November 2018. However there will still be some constraints. A consumption plan uses storage for all assets and by default an app service plan will use the file system. Moving FROM consumption TO app service should always work (pending deployment in November). Moving FROM app service TO consumption may not work though if you are using file system for storage.

                                  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.

                                  • 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

                                      • Allow comments in function proxies proxies.json file

                                        Either allow additional attributes that are specified in the schema to be present in the file, or allow JSON comments with some syntax or add explizit "comment" attributes to all objects in the schema. Big proxies.json are unreadable otherwise.

                                        • 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.
