Migrating Web service to Azure - azure

I think, previously cloud services (classic) used for any web service deployment.
What Azure service to choose for migrating Web service or Web API or WCF service ? What needs to be considered before and after migration. Is there any guide available?
Thanks.

Why should I prefer Azure App Service over .NET REST Web API?

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 Apparently it's outdated.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).

Azure - difference in publish website and deploy on Azure VM

What is the difference between publishing a website on azure and deploying it on an azure virtual machine?
Azure offers several ways to host web sites: Azure App Service, Virtual Machines, Service Fabric, and Cloud Services.
This article helps you understand the options and make the right choice for your web application.

Migrating MVC application to AZure Appservice and Cloud Service [duplicate]

What is the difference between an Azure Web Site and an Azure Web Role

I am using MVC application in VS2015.Now we are planning to migrate our MVC5 Web application to Azure app service. I am getting confused with cloud service with Azure app service.
Just wanted to check can we migrate MVC5 application to Azure app service ?
I have installed Azure SDK
Do i need to install VS 2017 to have Azure App service or with Azure SDK will work.
Does the cloud service project and Azure App service both are different?
Please help me in understanding more
There are many differences between Azure Web Apps and Cloud Services.
App Service Web Apps is a fully managed compute platform that is optimized for hosting websites and web applications. This platform-as-a-service (PaaS) offering of Microsoft Azure lets you focus on your business logic while Azure takes care of the infrastructure to run and scale your apps.
On the other hand, Cloud Services is an example of Platform-as-a-Service (PaaS). Like App Service, this technology is designed to support applications that are scalable, reliable, and cheap to operate. Just like an App Service is hosted on VMs, so too are Cloud Services, however, you have more control over the VMs. You can install your own software on Cloud Service VMs and you can remote into them.
More control also means less ease of use. Unless you need the additional control options, it's typically quicker and easier to get a web application up and running in Web Apps in App Service compared to Cloud Services.
In Azure App Service, deployment and management are integrated into the platform, sites can scale quickly to handle high traffic loads, and the built-in load balancing and traffic manager provide high availability. You can move existing sites to Azure App Service easily with an online migration tool, use an open-source app from the Web Application Gallery, or create a new site using the framework and tools of your choice.
Also, there are many ways in which one can perform direct code deployment to Azure App Service. You can use FTP/Kudu (Git/Mercurial or OneDrive/Dropbox)/Web Deploy etc.
Hope this clears your confusion.

Hosting a web application in Azure that consumes on premise web services and ActiveMQ

I'm looking at ways to host our web site in Azure. The Web application consumes on-premise web services and send/receive messages from ActiveMQ hosted on-premise. Is this possible? Any pointers will be helpful.
Short Answer: Yes, it's possible. Mixing Azure and On-Prem resources is what's called the Hybrid Cloud.
Long Answer:
You can use Azure App Service Environment to setup a Virtual Network with an Azure Web App that will allow for a VPN connection to be setup between your on-premises network and the Azure VNet. If VPN setup isn't an option of you, then you could use the Azure Service Bus Relay service to connect an on-premises WCF Web Service to the Azure Web App. Additionally, a Biztalk Hybrid Connection could be used to tunnel through the firewall between your on-premises resources and the Azure Web App. Hybrid Cloud is fully supported in Microsoft Azure and there are a few options to choose depending on which fits your needs / scenario best.
You can create a VPN on Azure, add the web site to it and then create a site to point VPN connection to add the VM that has the on-premise web service to it.
Another solution, if your web service is developed in WCF, you can use Service Bus Relay with your web service, this will make it accessible from your Azure web site.

Failover planning for Azure Mobile Services

I have an azure mobile service that is running on top of SQLAzure DB. The Database is geo-replicated. I am looking to setup a failover for mobile service in case if the primary endpoint goes down. I have looked into traffic manager but it does not support mobile service endpoints also setting up another mobile service that talks to the replicated DB not possible as the replicated copy is read-only.
What are the possibilities of setting up a failover for mobile services endpoints.
There are several mechanisms for hosting mobile APIs on Azure - Azure Mobile Services is tied to a single region, so you can't fail that over. Azure Mobile Apps is the next generation of Azure Mobile Services and is built on top of Azure App Service Web Apps - it's an extension of the work there. As a result, you can leverage all the cool features of Azure App Service for your mobile service. If you haven't taken a look yet, then take a look at migrating your service to Azure App Service Web Apps.
Once there, Traffic Manager is definitely what you want. You can read about the process of using Traffic Manager with an Azure web app here: http://blogs.msdn.com/b/benjaminperkins/archive/2014/06/02/using-traffic-manager-with-microsoft-azure-web-site.aspx
