Is it possible to host MariaDB as an average app service on Azure?
I would just like to install and maintain MariaDB similar as a web app on Azure App Service using the same pricing conditions as for it.
I am aware that there is a SAAS service "Azure Database for MariaDB" available, but I am not interested in that.
It is not possible to host a MariaDB on an app service in Azure.
If you do not want to go with "Azure Database for MariaDB", you could go rent a VM and manage it yourself. However, that would be the same thing as going with "Azure Database for MariaDB", just a little cheaper :)

I have a client coming on board to Azure from other cloud service provider. They would like to host up to 10 web apps on Azure and cost is really an issue for them.
Normally I'm suppose to create VM's that would host each of these web Apps; but they can't afford the price. Hence the choice of deploying all of them on the same Azure App service plan.
I think Azure App service offers only 50gb storage. The 10 Web Apps would require storage capacity far more than 50gb; is it scalable or can we link each of these Apps to an Azure storage account. And also is there any implications for deploying multiple web Apps on an Azure App Service plan
An App Service Plan is capable to run multiple Web Apps, each in its own sandbox. It's like a VM but as a PaaS service. Note that the storage included in the plan will be shared across all Web Apps so you'll have to use Azure Storage if you want to store more data.
An App Service Plan is designed to handle multiple web apps/Function apps, use BLOB Storage or similar for your data it will scale to whatever you need, depending on your needs you can add further services like Azure Front Door to load balance multiple apps on multiple app service plans
One important thing to remember is that the app service plan has limitations with outbound connections so even if each of your webapps are not so busy the sum of them all might bring you over the limit so be very careful how you handle your outbound connections.
Why should I use Azure App Service and not just implement a common .NET RESTful Web API backend?
What's the explicit benefit of this service compared to a common .NET RESTful Web API backend hosted on Azure?
An Azure App Service is a place to host your web application or API. Normally when you have a .NET web API you host it behind IIS or something on a virtual machine.
Azure helps you with these common scenarios wit Platform as a Service (PaaS). An App Service completely abstracts the operating system and the way you host your web application.
App Service can host web apps both on Windows and Linux. You can use all kinds of frameworks such as PHP, .NET or Java. You can even host containers without worrying about the host.
A good sample to start with hosting your .NET Web App on Azure App Services can be found here: Quickstart: Create an ASP.NET Core web app in Azure
Yes, there is a huge difference between Azure App Service and .Net REST WebAPI backend on Azure.
Hosting on Azure can be done using two ways
Create your own VM, then install IIS and do all the required stuff
Use AppService Plan
AppService Plan allows you to leverage the powerful functionality of Azure. Here a separate VM is not assigned to you. Azure App service can scale automatically depending upon the Scaling rule which is not present in restful API hosted on Azure VM.
My question blatantly was a stupid Newbie question, and as such, I'm afraid it is non-sense, which I now know by the answers you've given.
I'm currently reading the book "Azure and Xamarin Forms" to learn Xamarin and Azure. Apparently it's outdated. It suggests to "create a Mobile App on Azure". From the book that Mobile App is just a plain App Service running a RESTful Web API with EF, but utilizing completely different namespaces to do so.
My question targeted towards these other namespaces. I didn't see a reason for them.
Apparently, Microsoft noticed the same. There is no "Mobile App" available in the Azure Marketplace anymore.
Azure App Service is a PaaS solution from Microsoft hosted on Azure. You can think of Azure App Service as some sort of "Micrsoft Heroku", because they work on a similar fashion. For many REST Projects, it can save you hours, if not DAYS of development. It has automatic TLS like heroku, but it is hosted on Azure instead of AWS and it can integrate very well with your existing Azure resources. One common pattern is to host the REST API on App Service and use a database service from Azure such as Azure SQL or Cosmos DB (which is a NoSQL service that, from the point of view of your app, it operates as MongoDB, but can be configured to behave as other DBMS).
I have a large SQL server hosted in our infrastructure, and an Azure resource set up with VPN access to our servers.
I want to create an Azure Function that connects to this SQL server. It's going to be a webhook endpoint to save to that DB. I don't need the overhead of an App Service Plan, I want the lightweight Function and the cheaper consumption pricing model.
All the tutorials online refer to App Services and Hybrid Connections that don't appear to be available in to Azure Functions on Consumption Plans.
I also want to keep the connection string configuration in Azure, and not hard-coded in the source or publish (which will ultimately be via CI).
The Azure Function is currently coded in C# in VS2019, but I can change that if it helps.
How do I set this up?
This option is not available on consumption plan. There is a already user voice open for this.

Yes it is possible. You would need to use something like Hybrid Connection. Does not matter which IDE you used to create the function.Check out the following link.
The Hybrid Connections feature requires a relay agent in the network
that hosts your Hybrid Connection endpoint. That relay agent is called
the Hybrid Connection Manager (HCM). To download HCM, from your app in
the Azure portal, select Networking > Configure your Hybrid Connection
endpoints.

I have created dependency graph(between application and database ) of services with help of azure application-insights service map but I want to know about used other networking services between app service(application) and database ?
please help
It depends upon what networking services you have between your app service and DB.
If you are using Azure SQL DB, the traffic will flow over the Azure Backbone and will not be a bottleneck. If you are using a SQL Server inside of a VNET, it could be hitting any devices that you have configured.
If you would like to drill more into those services, you will need to see how those services are monitored. If you would like those services to appear on your Application Map when they don't, You can Leave your Feedback Here!
I have an Azure function under an ExpressRoute subscription that is trying to connect to an on-prem database, but fails to do so.
Is it possible to use Azure functions within ExpressRoute?
Thanks!
An Azure Function can be deployed on an App Service Environment. The App Service Environment is deployed on your own VNET which can have access to on-prem resources via ExpressRoute.
If you don't want to pay for an App Service Environment, you can deploy your Function on a dedicated App Service Plan and then use Hybrid Connections to connect to on-prem, or integrate the Function App to your VNET and create a Site-to-Site VPN to on-premises. These last 2 options option, however, won't go through ExpressRoute.
All 3 options are described here. You just need to deploy your Azure Function to an App Service Plan to get same features as an App Service.
HTH
Not without setting up a dedicated router virtual appliance (e.g. a CiscoASA VM from the Azure marketplace). Microsoft will say "not supported", but we were able to get it working in this manner.
