  1. Option to migrate windows WebApp to linux WebApp

    I would like to migrate my existing azure app service web app (running on windows) to new app service Web App on Linux. Now I try to do it through backup and restore and the contents are not copied to the linux web app.

      Thanks for that suggestion, can you please submit a support request to investigate why backup and restore didn’t copy the contents to the new linux web app.
      Note that backup and restore doesn’t move the *.azurewebsites.net hostname.

    • App Service Environments Architecture and Cost

      I love using App Service Environments; however, the cost is shocking. We like that our App service can communicate over our express route to our data center. I gained some new understandings with how these services work on the back-end and it seems confusing. I have an understanding that normal App Service Plans operate such that a fault tolerant pair is available in a different part of the data center and in the event of a failure, your code is moved to the other pair. This is great and I love that. With ASE's the architecture changes and the use…

      • 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.

        • Optionally stop the web app while backing up

          Some of my web apps have embedded databases that block the files they use. That prevents the backup from storing them (well, it actually stores a 0 byte file instead). This is not a big handicap if I make the backups manually, because I know the issue and I stop the web apps manually, but if I want to automate the backup I can't because almost always these files are locked...

          One possible solution would be to add an option in the backup configuration to stop the web app before running and start it again after it has finished.

          Thanks!

          • [Linux] Give Linux web apps same deployment options as Windows based apps

            Linux based web apps have 3 deployment options (GitHub, BitBucket, Local Git repo) whereas Windows based apps have 7 deployment options (including the "External Repository" which is what I was looking for).

            This request is to bring the options for Linux based apps up to speed, and perhaps until then, provide documentation and/or UI verbiage as to why there are differences. I spent an hour or two trying to hook up GitLab as a deployment option (including trying to use the Azure CLI) in vein.

            BTW the CLI gives a cryptic error message when trying to add an external repository.…

              • azure service environment (ASE) needs container support

                You recently announced general availability for the new azure App Service in Linux and Web Apps for Containers. However, I can't get them to work inside my Azure Service Environment V2.0, I found a menu item to allow me to add an Azure App Service in Linux to my ASE, and I initially specified a docker container, but looking at the construct after that reveals the container is gone and the thing was neutered to a generic webapp.
                Please enable your azure web apps with containers in ASE. These are, after all, just another variant of a webapp, and ASE…

                  • Linux Static Site on Nginx

                    One of the most common web techniques today is static generated web sites. Ideally, there would be an option along with Node, Php etc for Static HTML. This would allow configuration for just running Nginx web servers to host static sites.

                    • Provide an interface for dictating logic to the load balancer, or allow us to nuke instances

                      The load balancer for an App Plan is extremely simple minded in that it will always distribute load evenly.

                      This doesn't work in a production environment with real users.

                      e.g. if a webjob running on one machine picks up an intensive task from a queue, consuming all of the machine's resources, the load balancer will still forward users/requests to the affected machine.

                      Please provide some sort of control over the load balancer. Even just a basic interface to provide basic rules.

                      If you won't provide that, then at least instead allow us to nuke instances ourselves and provide us with…

                        For heterogeneous workloads, the recommendation is to split the apps apart into separate app service plans. For example, webjobs isolated to in an app service plan separate and apart from the app service plan(s) running web or API applications.

                        We will keep this item open marked as “under review” because there are plans to onboard the per-worker metrics to the Azure Monitor feature, at which point programmatic scaling decision can be made from those metrics.

                        Currently worker metrics can be viewed from the UX by clicking into “Diagnose and Solve Problems” link for an app service plan. There will be a link in the UX blade that opens titled “Metrics per instance”. Drilling into that link will pull up another UX blade showing CPU usage (amongst other statistics) broken out by individual worker VMs.

                        We would like to setup an automatic alert that fires when the file storage of an app plan is reaching its limits.

                        Ideally it will be great to have a metric that tells the % of storage (quota) consumed so we can set an alert on top of that metric.

                          This is a great idea and we would like to implement it though there are a few dependencies we need to meet first. We are leaving this on the roadmap for now to see if it gains more customer support which will help with prioritization.

                              Currently I am using VSTS for my CI/CD to azure web app linux
                              However, unfortunately, there's still a pretty significant downtime for every deployment.

                              I tried to create a staging slot to minimize the downtime, and swap to production. however, VSTS doesn't allow me to deploy to my staging slot.

                              I created a github issues too here https://github.com/Microsoft/vsts-tasks/issues/4460

                              If I can't deploy to my slot, what's the point of having slot in the first place? Please prioritize this as I think this is a pretty important feature

                              • Way to monitor Web App connections regardless of state

                                I had an issue where my web app was unable to open new connections because too many were open. The metrics-per-instance reports for monitoring connections only show open and close-wait state connections. For whatever reason the connections impacting my app were in another state and hence were not shown.

                                I believe I have resolved my issue, but I cannot check on the health of the app without asking an Azure support technician to assist.

                                It can also be misleading when troubleshooting to see 80 connections in the report, when there are actually 3500 in use.

                                Thanks!

                                • 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.

                                  • Enable 'client certificate authentication' per directory

                                    I have a site that only part of it needs to be secured with client certificate authentication, it is able to be enabled on the site level but not the directory level as per this article.

                                      Hi,
                                      thanks for the feedback. This is not currently possible as client cert auth on App Service is in require mode and as such cannot be delegated to folder level.

                                      We will review this item and your feedback, we may look to implement this capability based on customer prioritization.

                                      Thanks

                                      Andrew

                                    • Make Application Gateway WAF services available for non-ASE App Service plans

                                      The Application Gateway and specifically WAF are useful even for simpler apps because of the OWASP and general security protections afforded.

                                      App Service Environments are extremely costly compared to a loaded Standard S1 or Premium P1 App Service plan and the Application Gateway/WAF cannot be used without the ASE.

                                      While there are WAF solutions provided by 3rd parties it would be great if the Azure solution used for ASE's was also available for standard App Service plans.

                                      Thanks

                                        You can configure a web app from the multi-tenant app service to work with the App Gateway as described here. http://docs.microsoft.com/azure/application-gateway/application-gateway-web-app-powershell
                                        Your app will still be internet accessible unless you also use IP Restrictions (app → Networking → IP Restrictions) to lock down access to just coming from the App GW.
                                        Since there are still improvements we are going to make here it is marked as planned even though you should be able to use it now.
                                        Is it the same as an ASE? No. The ASE is a deployment of the App Service in your VNet. It’s hard to beat that from the multi-tenant App Service. Still, the aforementioned method should get you started.

                                      • Near-realtime consolidated web app consumption

                                        We need a consolidated way to see near-realtime CPU and Memory consumption for each Web App per App Service Plan. This way we can quickly identify which apps are consuming the most resources (specifically CPU and Memory) in that App Service Plan.

                                        These are the 2 scenarios we run into often:

                                        1. We run many web apps in each App Service Plan. We don't want to pay for a new App Service Plan until all memory (or CPU) is consumed on what we currently have. I could rebalance the sites (move some to another plan) if I could easily see…

                                        • Provide more secure TLS ciphers

                                          Currently Chrome flags the CBC ciphers as obsolete. CBC ciphers are at the top of the cipher preference list of Azure Web Apps as you can see there: https://www.ssllabs.com/ssltest/analyze.html?d=test.azurewebsites.net
                                          More info: https://www.chromium.org/Home/chromium-security/education/tls#TOC-Cipher-Suites


                                          So please provide some more secure ciphers from the ECDHE cipher suite like TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256.
