Add static IP address for outbound traffic without the use of App Service Environment
There are many reasons you may want to have a static IP address for outbound connections. For example, you may be accessing a system which requires you to whitelist IP address in a firewall, such as SQL Database or an external service.
Currently, the only way to get a static IP address for outbound connections is to use App Service Environment. App Service Environments are quite complex, and has a very high price tag. You need at least 4 instances, 2 of which must be P2, meaning you'll pay at least 1000 EUR/month. Paying 1000 EUR/month just because you want…

Support Double Wildcard Custom Domains
For multi-tenant applications, we require the ability for Azure to support double wildcard custom domains.
Single wildcard custom domains are currently well supported, i.e.
*.mydomain.com
catches all unmapped, single subdomain urls e.g. level1ex.mydomain.com, level2ex.mydomain.com etc
The issue (which isn't documented: see forum post below) is that secondary level wildcards are not supported at all by Azure:
e.g. www.level2.mydomain.com will result in a 404 error.
Why is this important? in a multi tenant environment, with lots of customers on different subdomains, it is best from an end-user perspective to support a www. subdomain prefix, as that's what 99% of non-technerati do…
443 votesthis feature has been postponed as it wouldn’t be complete and might be revisited later if standards/supported features by CAs and browsers change (double wildcard certificates are not supported standard, resulting in no way to secure double wildcard domain)

Antimalware feature on Web Apps (App Service)
Cloud Services and Virtual Machines have an antimalware feature to protect themselves from viruses.
However, Web Apps only protects their platform, and there is no customer-facing antimalware service now.
If we develop an application which receives files from anonymous users with an upload form, we can't detect and get rid of the viruses.
We strongly request the antimalware feature like that Cloud Services and Virtual Machines do.349 votesThere are no near term plans to provide this functionality. However we will keep it under review for periodic re-evaluation in the future.
Thank you,

Provide .NET language packs on Web Apps
I'm working on a website that uses System.ComponentModel.DataAnnotations
On my local machine, model validation messages are displayed in french but they are in english when I deploy the website to Azure.
Please install .NET language packs on Azure Web Apps so we don't have to create .resx files and messy code to override .NET built-in messages...

Scale Out wait for WarmUp complete before being added to LoadBalancer
When adding new instances to the LoadBalancer, scale out mechanism doesn't wait for those application instances to fully warm up.
Availability checker, via AppInsights, logs these responses, with the header:
'X-AppInit-WarmingUp: 1'Which means that IIS knows that the application is in it's WarmUp cycle, but the LoadBalancer is already trying to serve requests.
N.B. we can add a rewrite rule to redirect the user to the original request, and hope that the LoadBalancer sends the user to a ready instance - but this feels like a hack.
329 votesThanks for the feedback. We are thinking of ways to make the warmup model better and fully ready for the app’s traffic. Right now, we just see the instance is ready before directing traffic.
Please refer to this blog post for more information about slots and AppInit.

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.

Allow Azure App Service IP Restriction configuration by PowerShell Script
At the moment an Azure App service has the ability to white list IP addresses through the Networking > IP Restriction blade. It would be useful if this could be configured through PowerShell.

Custom request headers in web server logs
This is generally useful, but my usecase if with Cloudflare:
When a web app is behind Cloudflare, all visitor IPs come Cloudflare's IPs. Cloudflare does forward the original visitor IP with a custom request header. I want to log this value in my web server logs. In IIS this is achieved with Advanced Logging, but this capability does not seem available in Azure web apps.

Ability to incrementally create/update AppSettings & ConnectionStrings
Actual problem:
Today if we don't provide all of the existing AppSettings or ConnectionStrings, the ones we omit are removed.Feature:
A little bit like the ARM deployment mode, add the ability to specify an Incremental & Complete mode when pushing settings. To ensure compatibility, Complete would be the default, keeping the behavior we have today. If we set the mode to Incremental, only the provided settings would be created/updated, leaving existing settings untouched.Use cases:
This would be very useful in cases where we want to sync AppSettings or ConnectionStrings for resources directly in our ARM templates for only…200 votesThanks for the suggestion, we are looking into the feature request

Metric and alert for Web App file system used quota
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.

Enable 'Connect', 'Log Stream', 'Console' etc for App Service Environment
When you deploy an App Service into an App Service Environment behind an ILB, much of the UI is greyed out. Examples of this is the 'Connect' button, 'Log Stream', 'Console' etc.
I have to manually construct a URL to get to the kudu endpoint right now in order to use the console.

Associating Hybrid Connections to Azure App Services cannot be automated

The Always On setting should have an option to make it sticky to the slot when swapping
This is odd it isn't this way by default but should at the very least have an option to make it sticky so as to not break anyone's current practices (in fact, shouldn't more settings have the option to be sticky?).
The issue here is that an always on slot consumes resources. If for example each app consumes 200Megs of RAM, and I have 5 app services running on a service plan, each app service has 2 slots for swapping, then I need to have Always On turned on unnecessarily for 10 slots (2gigs of RAM consumed for nothing).

Restart App Service Plan (all Web Apps in a plan), something similar to iisreset, from within the portal
It would be great to have a restart button, similar to the restart button in a Web App, but on the App Service Plan level to restart all Web Apps in a plan. something similar to iisreset.
110 votesHi Ibrahim,
What issue are you trying to solve? What use case would this be used for?
It seems to me that placing a restart option on the plan level might do more harm than good, by resetting the memory on all the apps under the plan. Depending on your scenario, auto-heal would be a great solution to solve individual machine issues. See a video by my colleagues here for more details: https://channel9.msdn.com/Series/Windows-Azure-Web-Sites-Tutorials/Auto-Healing-an-Azure-App-Service
Placing this idea under review for now until I understand what’s at the base of the request here.

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
100 votesThere 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.

Permission for accessing Performance counters
We would like create a custom monitoring solution for our Azure Web Site based projects. Unfortunately the web site and job processes do not have permission to read performance counters.
