  1. Add Application Initialization Support for Scale Up/Down

    The application initialization/warmup feature works great when scaling out/in, but when scaling up/down requests are immediately routed to the new instances before the application is warmed up. It would be great if the new instances could be warmed up before rerouting requests to them.

    • Associating Hybrid Connections to Azure App Services cannot be automated

      There is no way to associate a Hybrid Connection to an Azure App Service via ARM Template or PowerShell.

      This is a significant gap since we cannot automate this at all when that is the driving factor for DevOps and PaaS services.

        • FTP accounts tied to subscription, not user. Not enough auditing

          In the current model, FTP credentials are tied to a user's azure login. Thus, we have no visibility into credentials that are set, as we cannot see other people's FTP credentials they've set. Furthermore, when an FTP account is created or deleted, nothing is logged. This makes it difficult to audit who has access. With the logins being tied to the user, when the user leaves, there is no way for us to reclaim that username unless they delete their ftp credentials first. This doesn't always work, as a user may depart abruptly or not on good terms. Although the…

          • Add "Allow access to Azure services" in Azure App Service IP restrictions

            Re this thread

            https://www.yammer.com/azureadvisors/#/Threads/show?threadId=945875058

            I'd used PowerShell to manually add IP restrictions a couple of weeks ago. Right away my App Insights availability tests started failing so I narrowed the test location down to Dublin IE and allowed those IP/Subnets.

            Add an option similar to SQL Server "Allow access to Azure services" That white lists Azure App insights availability tests for selected regions.

            Thanks

            Luke

              There was some confusion about this feature due to the documentation for it and UX originally released had a bug.

              The IP Restrictions feature works as an ALLOW list, rather than a DENY list as originally stated.

              The ask here is still valid, there are other services in azure (like SQL) that have UI to explicitly allow other azure services to reach the database. While this is convenient for development scenarios, it’s not a good idea for securing the resource.

              We’ll keep an eye on this request and see if it gathers more up-votes.

            • implement a graceful restart an Azure Web App with multiple instance

              We would like to have feature through which we can perform the configuration changes through portal without down time when there are multiple instances are available. The similar stuff is available in advanced restart where you can define the delay between restart of each instance.

              • Allow control of the ARRAffinity set cookie response header

                Problem:
                When a request for contoso.com hits an Azure App Gateway and the back end is routed to contoso.azurewebsites.com, the set ARRAffinity cookie response includes the optional domain attribute (as per RFC6225 Page 22) that specifies "contoso.azurewebsites.net". causing the user agent to never write the cookie since the Domain attribute doesn't match the requested domain.

                Proposed Solutions:
                Solution #1
                Give us a way to disable the Set Cookie: domain attribute similar to the way we can add a "Arr-Disable-Session-Affinity" response header to disable the cookie entirely. I'm suggesting an "Arr-Disable-Session-Affinity-Strict-Domain" response header to tell the ARR proxy not to write…

                • It should be possible to renew/replace an SSL certificate via ARM templates

                  When I deploy an ARM template (that has previously been deployed) which contains a certificate, I would expect that the certificate would be updated/replaced when the pfxBlob has changed.

                  {
                  "type": "Microsoft.Web/certificates",
                  "name": "[variables('appService_name')]",
                  "apiVersion": "2016-03-01",
                  "location": "[parameters('resourceLocation')]",
                  "properties": {
                  "pfxBlob": "[parameters('sslCertificateData')]",
                  "password": "[parameters('sslCertificatePassword')]"
                  }
                  }

                  The current behaviour is that that the deployment will succeed and the certificate will not be updated. This is not intuitive.

                  Currently, to work around this limitation, it is necessary to remove the existing SSL binding and certificate via the portal or Powershell.

                  Remove-AzureRmWebAppSSLBinding -Name $bindingName -ResourceGroupName $resourceGroupName -WebAppName $webAppName -DeleteCertificate $true

                  • Make Vnet sticky to slot

                    When switching slots currently if you have a vnet on one slot and not the other, the vnet is switched between slots. As this vnet may be pointing to a testing environment on one slot and a production environment on the other slot, it would make sense to have this be a sticky setting to the slot, with the option to make it global across the app in the case that all slots will be using the same vnet.

                    • Idempotent swap slot operation to support swapping via ARM template deployments

                      This would simplify deployment governance (no need for an out-of-band swap operation when doing a deployment). Ideally the API would look something like:
                      PUT Microsoft.Web/sites/mysite/swapstate
                      {
                      "properties": {
                      "slot": "staging", // The slot to look at
                      "type": "oldest|newest" // Whether the oldest or newest bits between the "active" and the specified slot should be taken. This allows our operation to be idempotent and predictable.
                      }
                      }

                        • App services should show the max supported version of ASP.NET core

                          If you deploy an app with a version of .NET Core that isn't deployed on Azure yet, you get horrible to debug errors that you have to enable stdout logging on to get to the bottom of.

                          (Ultimatly editing csproj with PublishWithAspNetCoreTargetManifest set to false)

                          Confusing and time consuming. It would be great if Azure showed you some where on the app, a max supported version of .NET core and some kind of publishing warning if you try to push something higher.

                              Have you tried looking into App Service hosted on Linux:
                              https://docs.microsoft.com/en-us/azure/app-service/containers/app-service-linux-intro

                              While the deployment won’t pull all your dependencies, you can still used a blessed image for your stack and even containerize your solution and host them on Linux.

                              One more item to look at is the new CLI “up” command we have for creating apps. You can check the quick session we had at Microsoft Ignite about this feature:
                              https://myignite.techcommunity.microsoft.com/sessions/66652

                              We’ll leave this under review to see if there are any improvements to our deployment that will happen as part of Linux hosting.

                              Thanks,
                              Oded
