I'm exploring Azure but unable to figure out how to allow my App service to connect to the VNET I created so it can access the HDInsight cluster.
My scenario is this, I'm running a Kafka HDInsight cluster deployed in the VNET I created and I need to also deploy my Azure Web App for Container in the same VNET so it can connect to the Kafka brokers.
I haven't seen a good documentation on this, need help on how to set the Azure app service to connect to my VNET over a private network?
The Network is disabled (don't know why) on my App service.
Thanks
VNET integration is not available yet for Web App for Containers or App service on Linux. Please follow the UserVoice request for updates on when it will be supported.

I have an existing linux VM on Azure that has PHP + MySql legacy system running on it
I also have a Flask Webapp running under same Azure subscription
is it possible to the Python WebApp reach the existing MySql database running on Linux VM using the existing internal network ?

It seems that you want to access MySql database on the Azure VM from Azure web app hosted in azure app service. If so, it's possible to integrate your app with an Azure Virtual Network.
You could have a quick start in that document, just note that there are two forms to the VNet Integration feature:
Reginal VNet integration. One version enables integration with VNets in the same region. Currently, this feature is still in preview but is supported for Windows app production workloads and Linux Web App for development and integration testing purposes. Read more details here.
Gateway required VNet Integration. The other version enables integration with VNets in other regions or with Classic VNets. This version requires the deployment of a Virtual Network Gateway into your VNet. It is only supported by Windows apps.
Additionally, Since VNet Integration is extended to use Azure container instance. For Linux web app, you could deploy it on Azure container instance in a VNet. See the template. This feature is currently in preview and you could know some limitations about deploying container instances into an Azure virtual network.
If your web app is hosting on other Azure services like Azure VM, you could use VNet to VNet connection or VNet peering or VPN connection to enable the communication between the two different virtual networks. Read more details here.
Hope this could help you.
We have got VMs on Azure and services are running in there.
We are trying to deploy our MVC Web application to Azure App service, which accesses some of the services from the VM using the private IPs but it can't connect to the service hosted on the VM using the private IP. We were assuming that all of our resources will be in the same network, can anyone help with this?
Thanks
Azure App service are having two kinds of hostings
Single Tenant (App Service Environment) which is dedicated to the customer
Multi tenant ( shareable across other customer subscription inside a data center scale unit)
If your application is hosted as multi tenant application meaning app service URL {WEbAppName}.Azurewebsites.net then its internet facing application and if it needs to connect to any VNET (Virtual Network) hosted service then it needs to integrate to any or same VNET.
How to do App service VNET Integration:
https://learn.microsoft.com/en-us/azure/app-service/overview-vnet-integration#regional-virtual-network-integration
Once the App service integrated with VNET then ideally it has connectivity with all the services present inside the same VNET or with peered VNET.
How to confirm connectivity from App Service to VNET hosted resource.
Go to App Services application => Advanced tools or console => perform below commands sequence wise as the HTTP communication happens through this sequence:
nslookup {Destination_FQDN} {Optional-DNSServer}/nameresolver {Destination_FQDN} {Optional-DNSServer}
tcpping {Destination FQDN}
curl -v {DestinationFQDN}
Common Scenarios:
If you're receiving connection refused it means its NSG is not allowing the communication.
If you're getting request time out it means it could be due to firewall or no proper routes to reach to destination.
If its connection abort it means its intermediate device is not passing connection through.

How do I connect to a database on-premises from an Azure WebJob or an Azure Function? Is this even possible?
I've been recently researching this and have found there a 3 avenues to connect app services to on prem database, as of today anyway.
Hybrid Connection, VNET Integration or App Service Environment
The later 2 options require VPN or Express (I think) connectivity to a cloud VNET. The VNET Integration option requires a separate VNET with PointToSite gateway connecting to your existing VNET. The App Service Environment is a quite expensive option as your App Service Plan is actually hosted inside your VNET, no longer being a shared host.
We are in process of moving our on-premises services to service fabric and planning to host it on Azure Service Fabric cluster. These service will require access to resources which are on-premises (corp network) and we currently can not move them.
What are the options we have? In past, I've used Hybrid connection for Azure web app but I'm not sure how this can be done for services hosted with Azure Service Fabric.
Your cluster runs on nodes in a VM scale set. The nodes are connected using a VNet. Regular VPN rules apply.
So Point to site, site to site and express route should all work.
You'll need to use ARM to configure a cluster to run in an existing vnet.
I'm considering Reliable Actors right now that's part of Service Fabric. I have an existing Web App that I'd like to keep and act as an API surface to my actors. The Web App will also handle authentication and authorization before any calls get to my actors.
I can't tell from the documentation, but is it possible to connect a Web App to Service Fabric? Additionally, is it possible to limit connections to Service Fabric so that it doesn't except any public connections? How would I go about setting this up, or is it even advisable to do something like this?
I know with Cloud Services, you can connect a Cloud Service to a Web App through a Virtual Network, so I'm at least familiar with that kind of setup.
You would do it the same way you do with cloud services - use a virtual network. Service Fabric is just a framework running on VMs in a cloud service.
Connection to the service fabric can be controlled through the loadbalancers in the cluster VNET. I would suggest that you integrate the WebApp into the Service fabric cluster VNET, to do that you will have to add a VNET gateway
