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. Code-To-Function - Specify git location for the function code.

    Code-To-Function is idea similar to the Code-To-Container when where Azure function has only pointer to the function code git location.

    Additional features could -"well known branches" where master is associated with prod and trunk with pre-prod deployment slots.

    The failure of the exxecutin would configurably create an issue in the Git

        Azure Functions should have a Marketplace to quickly launch serverless apps like

        url shortners, redirection apps, Scheduled DB sync apps, simple umbraco like cms, PWA templates etc

            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."

            • Trigger Azure Function From Azure File Storage

              I'm having the need to use an Azure file storage trigger binding but I have seen that they have not fully supported yet [ref](https://docs.microsoft.com/en-us/azure/azure-functions/functions-triggers-bindings).

              I would like to know if it will be possible in the near future to implement file storage triggers.

              Is there a schedule in the roadmap?

                • Add Functions 'Experimental Language Support' button back to the portal to create python, etc functions

                  Please put the 'Experimental Language Support' button back on the portal when creating new functions. Having to use the cli to create the experimental language functions (python, php, etc) is much slower than simply clicking a button and using the portal editor.

                    • 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.…

                      • Function inputs with query or path support should be able to make use of query/body parameters

                        The documentation for SqlQuery inputs mentions that this capability is not *yet* supported, and points to a GH comment, but I saw no actual feature request so here it is.

                        https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-cosmosdb-v2#http-trigger-look-up-id-from-route-data-using-sqlquery-c

                        "You can pass route data to the SqlQuery parameter as shown, but currently you can't pass query string values." (link to comment https://github.com/Azure/azure-functions-host/issues/2554#issuecomment-392084583)

                        Is there any sort of timeline that users can expect this?

                        Also, I think the documentation could be improved to explain that the Route Templates are based on ASP.NET routing, which is where the limitation stems from (because route templates in ASP.NET do not encompass…

                        • Select existing Application Insights ressource on Azure Functions creation

                          It is a real pain to create a new function using an existing App Insights ressource:
                          1. Create function with Application Insights enabled
                          2. Wait for the function to be created
                          3. Go to Azure functions -> platform settings -> all settings -> application insights
                          4. Press "change" to bind the function to an existing App Insights resssource
                          5. Go to App Insights
                          6. Locate the newly created default App Insights ressource for the function and delete it

                          • Allow customers to select the VM size their consumption plan runs on

                            It's my understanding functions execute on an A1 size virtual machine, which has 1 core and 2GB memory. The customer has no way of changing this.

                            Our processing requires a bit more beefy machine as it's CPU and memory intensive. We understand using a dedicated App Service Plan is an option, but we really like paying for only what we consume. Our jobs run infrequently and tend to be on the "longer" end of the run time scale.

                            I'd love to be able to select the VM size we run on and pay accordingly with a consumption plan.

                              We’re planning a new offering that allows fast scaling based on events, while you can select the VMs where your functions will run. This will allow for further networking options to connect to on-prem resources.

                                Would be great to see the current health of all functions in a single view. Black for successful, Orange for functions with warnings and Red for functions with errors on last execution.

                                Also, last x runs in a color-coded graph (same as last x builds in VSTS) would be brilliant so we can quickly visualise the health of our function apps.

                                  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.

                                  • 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

                                    • Wildcard within path of blob input bindings

                                      I wish we could specify blob storage input bindings path that included wildcard.

                                      --- function.json
                                      {
                                      "type": "blob",
                                      "name": "faces",
                                      "path": "face/profile-{date}-*.png",
                                      "connection": "AzureWebJobsDashboard",
                                      "direction": "in"
                                      }

                                      Then, I hope to process these as array of Blob objects.

                                      ---index.js

                                      module.exports = function (context, myQueueItem) {
                                      const fileSizeList = context.bindings.faces.map(face => face.size);
                                      context.log(fileSizeList);
                                      context.done();
                                      };

                                      • MQTT Subscriber trigger support as a first class trigger

                                        Please add support for listening to MQTT 3.0 and 3.1 servers as a subscriber for a trigger. This would be immensely useful in IoT scenarios.

                                        • allow function to specified as a value on the exports, not exports directly

                                          Currently, for JS functions, you must assign the function to `exports` which is of course allowed in node, but is becoming less standard. Allowing a function specification e.g. `myfunction` that is a key inside an object assigned to exports would be helpful especially with some transpiled languages.
