Azure App Service, Mobile Apps or Api Apps; what is the difference?

Question

I have reading about the new Azure offerings and trying to figure out what is what. The documentation I have been finding all over seems to have more information about the frameworks that are not valid anymore like this one here. Most of what they talk about at 4.8, 5.23, 12.13 into the video are no longer valid.

So far what I understand is that Mobile Services was offered in the past. That will soon be discontinued and App Services will take over. App Services are the top level services that contain Api Apps, Mobile Apps and Web Apps. Is this correct?

I am confused as to why we have Api Apps and Mobile Apps. Don't they do the same thing? And now that we have Web Apps in addition, are they only limited to UI related applications? The only simple thing to understand and one that has no similar other offering is the Logic app. This seems to be something that can only be done on the Azure portal. Visual Studio has no project template for it. Is there something that needs to be installed for creating logic apps in my visual studio only?

Also, in Visual Studio 2015 what is the difference between the Asp.Net Web Application project template under the WEB node and the CLOUD node? They both seem to be holding the same templates within.

Why do we have Azure Mobile App and Azure Mobile Service right under the Cloud node like here below..

..and also after selecting Asp.Net Web Application

On the face of it, both look the same. Are there any subtle differences that one needs to know about? Also, why are all these options also not available for Asp.Net 5 templates? With all the changes happening is it a good idea to put apps developed under the latest versions to production?

Thanks for any pointers.

Azure Mobile Apps are the next version of Azure Mobile Services. Azure Mobile Services has been deprecated, and you can't provision it on new subscriptions. Mobile Apps has a lot more features over Mobile Services. To learn more, see I use Mobile Services, how does App Service help? .

Mobile Apps, Web Apps, and API Apps are all essentially the same thing, they just have some extra features for building particular solutions. You publish each of them to an App Service Plan, which is the actual underlying VM that hosts your service.

Once you've provisioned one of these app types, you can publish a Web API to it, regardless of what app type it is. For instance, you can publish your API to a Web App or Mobile App. Once you've picked a particular app type, you aren't locked in, you will just see a slightly different UI in the Azure Portal.

Mobile Apps also have a Mobile Server SDK for Node.js or .NET. The .NET server SDK is an extension of ASP.NET Web API. It doesn't yet support ASP.NET 5, mainly because there is a dependency on the OData library, which doesn't yet support ASP.NET 5. However, Mobile Apps is under active development and will support ASP.NET 5. Unfortunately, we don't have a timeline to share, mainly because not all the dependencies are complete.

For Mobile Apps in particular, you get the features of client SDKs that support authentication, offline sync, and push notifications. The easiest way to learn about the offering is to follow the quickstart guide: Create a Windows app on App Service .

You can learn all about the SDK and try them out, even without an Azure Account. Here's documentation about the .NET server SDK: Work with the .NET backend server SDK for Azure Mobile Apps .

API apps have a few extra features like creating a metadata endpoint for you automatically, which you can then use to generate client library using Visual Studio.

Currently, only Web Apps and Mobile Apps have a demo experience available at Try App Service , but you can see the API experience if you use a Microsoft Account to sign in, and then manage the app in the Azure Portal. You will see all of the API app and Mobile App options in the portal.

Note that Web and Worker roles are part of Cloud Services, and are a totally separate service. To learn about the difference between these, see Azure App Service, Virtual Machines, Service Fabric, and Cloud Services comparison .

Answer 2

I just describe what is the difference between Azure App Service, Mobile Apps and Api Apps, hope it helps:

• Web and Mobile Apps o Mobile Apps offer a mobile application development platform with a rich set of capabilities. Based on Azure Mobile Services, Mobile Apps provide developers with a comprehensive set of client SDKs including Windows, iOS and Android as well as multi-platform environments such as Xamarin and Cordova. With Mobile Apps, you can easily send push notifications to your app, add login, and store data in the cloud with offline sync to any mobile client.
• With API Apps, you can select from a rich library of existing on-premises and cloud APIs as well as contribute their own APIs easily for public or private use by Logic, Web, and Mobile apps in Azure App Service.
• Azure app service, is a solution for creating web and mobile apps, is a cloud services that unifies everything you need to quickly and easily create enterprise apps that run on any platform or any device.

Azure app service is composed of: Web Apps, Logic Apps, Mobile Apps and API Apps
