I have site to site VPN from my Azure VM to an on premise network.
May I know how can I deploy the code on Azure VM such that the site to site network stays?
Just for the sake clarity lets reiterate that A Site-to-Site VPN gateway connection is used to connect your on-premises network to an Azure virtual network over an IPsec/IKE (IKEv1 or IKEv2) VPN tunnel.
After site-to-site VPN is operational, network on both sides of VPN would be treated as one virtual network. This enables cross network accessibility of network resources as defined in access configuration.
Your questions needs clarity as I do not believe "the code deployment to a VM" would interfere "the network configuration" where the VM is housed.
It would be helpful if you could you add details to your question like error etc, in the meantime adding few pointers to get you started on VM creation and deployment.

We have an on-premises data centre that is connected to Azure via VPN.
There are some on-premises Jenkins jobs that need to run when code is pushed in the Azure repository, and there is an on-premises Nexus server to store artifacts from other Azure pipelines. The rest can and should run in Azure.
I know there is a possibility to use a self-hosted agent that is placed in the Azure virtual network which could then connect to on-premises, but we do not want to manage/pay for a self-hosted agent.
My question is, is there something like a virtual network integration for Azure DevOps? The idea is to let DevOps connect to on-premises resources via the Azure VNet and the VPN without self-hosted agents in between.
E.g., does the ARM Service Connection only allow to access resources like VMs for deployments or does it also allow to connect to a VNet and the via VPN connected resources on-premises?
Thanks in advance!
I have already created a service connection between DevOps and the Azure subscription. I cannot check weather the connection to on-premises works for internal reasons.
The Microsoft hosted agents for Azure DevOps only allow for public internet connections to other resources. VPN and Use of expressroute or other connections to the internal corporate network are not supported. See this section of the docs for reference.
I am currently setting up an Azure logic app with an AS2 connector.
Now I am being asked to connect to the partner via VPN. From googling I think that is possible to somehow add the logic app to a VNET and then setup a site-to-site VPN gateway.
It is my first time to work with either Logic apps or AS2.
Question:
Is it possible to setup an Azure logic app with AS2 connector that connects through a VPN?
How might I do it?
Yes, it's possible.
First of all, you need to connect to Azure virtual networks from Azure Logic Apps by using an integration service environment (ISE), With ISE, you deploy the Logic Apps service into your virtual network.
When you create a logic app or integration account, select your ISE as their location. Your logic app or integration account can then directly access resources, such as virtual machines (VMs), servers, systems, and services, in your virtual network. This virtual network can be an existing VNet that has a VPN connection to the partner or you can select an Azure VNet as a peer for your environment.
You may note those prerequisites before your deploy ISE, and your ISE needs four empty subnets that aren't delegated to any service. You also can optionally set up NSGs by filtering network traffic across subnets.
Here is a detailed explanation in this blog--Introducing Azure Logic Apps Integration Service Environment (ISE).

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.

I have a VM running SQL Server in Azure East US2. I also hosted a webapi as azure web app. Connection string used in webapi is being routed through internet gateway right now. I want to ensure that both of these services are hosted on same data center so that they communicate over LAN instead of internet gateway.
I was trying to setup a VNET and when I tried adding this VNET to webapi, it asks to setup VPN gateway. Why do I need to setup VPN gateway, are they not aware of being on same data center. Can't they be put on LAN without setting up VPN.
When you deploy both your VM and your Web App in Azure East US2 they land on the same geo-region. Please note that a lot of Azure Regions do have more than one facility (the thing you call Data Center), and you have no control over where exactly within a region (i.e. East US2) your resource will be deployed.
Now, if you want to talk to your SQL Server on an Azure VM from the Web App, you have to use VNet integraton. Because you are not deploying into a App Service Environment, you have to connect your web app to the VNet where your SQL Server is. The way to do this is by implicitly utilising a Point-to-Site VPN Connection between your web app and your VNet.
Do not worry, the whole process is automated and you do not have to deal with certificates and certificate roll-over, but there is a need for VPN Gateway. That's way you are being asked for the VPN Gateway.
But you should really consider using Azure SQL DB instead an SQL Server on VM.
