I am currently creating a dashboard for a complex backend that should be hosted on an Azure Cloud Service due to performance reasons. Unlike our older projects we want to implement our dashboard as single page application based on vue.js, but after doing some initial research I am aware of difficulties when it comes to deployment.
The idea is to have a frontend project and an ASP.NET Web Api that offers the respective data for the dashboard. Both projects should run inside the cloud service.
What would be the best approach to deploy single page applications to a cloud service? Since we prefer Visual Studio Code over Visual Studio for frontend-related tasks, it would be great if we won't depend on specific features VS offers.

I've been studying Xamarin.Forms with goal of building cross-platform mobile app in VisualStudio2015. I've got a perfectly acceptable public facing web site but native app(s) are what the boss thinks we need.
The current web app hosted on IIS 7.5 uses a separate project(DLL) for database access to an on-premises SQL Server 2008 instance. This VStudio project exposes domain objects to the calling ASP.NET webforms by executing various stored procedures using System.Data.SqlClient.
I know building the mobile native app itself with Xamarin.Forms is one part of the challenge but I am asking here for clarification about how to approach the database requirements:
Do I need to create some sort of web service that provides the same CRUD functions required by my current web site?
Xamarin documentation lists several options for consuming web services and the more I search and read about data access I conclude that a callable web service of some type is going to be required for my eventual native mobile app.
Is this assumption correct?
Yes. You generally want a webservice layer brokering requests between your mobile app (or any remote client) and your DB server. If you already have all your crud operations in a separate library that is utilized by your website, then a webservice would just be another set of endpoints that rely on the same CRUD library.
A noob's question. I consider using a Cloud Service instance to host a web-app, but my app is based on ASP.NET 5 beta8. Visual Studio tooling doesn't allow me to add an ASP.NET 5 app into a Cloud Service project (which could make it trivial to deploy).
However, it is still just an app. So there must be a general way to put it in, right? Or is it possible only through VS tools?
Your question is a duplicate of: How to convert a ASP.NET 5 Preview Web Project to Cloud Service
The answer in that thread:
It's not supported yet. But, if you want, you can create a setup script that installs all the needed components and then you can follow the steps from this post to run it and bootstrap your app: http://www.codeproject.com/Articles/331425/Running-an-EXE-in-a-WebRole-on-Windows-Azure
I'm playing with Azure asp.net development. I use Visual Studio 2010, with Azure SDK and I'm a newbie to Azure cloud.
I created several apps and deployed them to my testing Azure Web Site. Everything works fine - ASP.NET Web Page, ASP.NET MVC3, even simple GridView binding to an Azure SQL database, which I created earlier and that I manage with Microsoft SQL Management Studio, using ADO.NET. It's really simple.
Now, I learned from some tutorials, that I need to use a Windows Azure Cloud Service Project to make sure that my application will work. But it works without this project, too. So what exactly do I need such a project in my solution for?
There are actually three different ways you could have gotten your ASP.NET app over to the cloud, and the confusion comes because you are seeing elements of two of those options.
A Windows Azure Web Site is just a single ASP.NET application running in Microsoft's data centers (versus on premises) so all of the configuration it needs is already part of the project itself (primarily the web.config), some being exposed via the Azure portal. In many ways, this is similar to web hosting providers.
A Windows Azure Cloud Service is a collection of multiple services, which could be web sites/services (Web Roles) or backend code (Worker Roles). The code for your Azure Web Site could also have been deployed exactly as is as a Web Role, but in that case it would be part of a larger application that potentially contains additional Web and Worker Roles. It's the Cloud Service project itself that provides the additional configuration of those web and worker roles (even if you have just a single role in the cloud service). The Cloud Service offering is considered Platform as a Service.
The other option, for completeness, is to create a Virtual Machine image yourself, install your ASP.NET site, and then have Windows Azure host the Virtual Machine. It's at the opposite end of the 'make it simple to deploy' spectrum, but you get a lot of control over what exactly is on the VM that you deploy. This is the Infrastructure as a Service offering from Azure.
I'm going to assume you're developing for Windows Azure Cloud Services (the foundation PaaS solution of Windows Azure). The Cloud Service project defines your application to the Windows Azure Fabric. If you don't already have one, then odds are your are running your application outside of the local Development Emulator. If you are going to deploy your solution to Windows Azure Cloud Services, you will need to create this project for your application so Windows Azure's Fabric (the secret sauce that will manage your application) knows how to manage the application.
And I'm going to assume the opposite to #BrentDaCodeMonkey - that you're developing for Azure Web Sites, and not Cloud Services - in which case you may have confused yourself with the tutorials, as I don't believe a Cloud Services Project is either necessary or advisable.
I want to add two applications inside one web role in Windows Azure. I'm using Visual Studio 2010.
There are a couple of ways of doing this.
The azure web role accelerator supports having multiple sites in a single web role (see https://github.com/microsoft-dpe/wa-accelerator-webroles). The documentation online regarding this is a little out of date due to the project having been discontinued. However its simple to setup. Just download the stuff from Github, compile and deploy the project from the download to your azure web-role, this then gives you an admin site where you can setup multiple applications within the web-role. You then deploy your application to there using web-deploy.
You can also add multiple sites to the service definition file, see http://www.wadewegner.com/2011/02/running-multiple-websites-in-a-windows-azure-web-role/ for an example of doing this.
This is a pretty vague question but I'm struggling a bit to get my head around what is involved in cloud hosting.
Say for instance if I had an asp.net web app using:
- Webforms
- linq to sql
- an sql server database
- Calling some external restful webservices
What would need to be done to host it on a cloud service?
Are there specific code changes that would be required and do these need to be considered in the initial design?
Can sql server and linq to sql be used in this type of setup?
What platform if any would be best suited?
in it's most basic form, Azure is just a highly available web-hosting environment - if you have an ASP.Net web application, you can deploy it to cloupapp.net and it should work.
To try it out, get yourself a Vista/7 machine, download the Azure SDK and VS Tools, and create a new Azure application. There are 2 main parts at this point, the Cloud project, and an ASP.Net Web Application. The ASP.Net will have a "web-role" relationship with the Cloud project. This is as it sounds, it is the visual front-end to the Cloud application, that interacts with visitors.
You can, at this point, just leave it there - it's a normal ASP.Net application with very good hosting. Your SQL connection strings should work, though you may want to consider SQL Azure. You can also host WCF services.
As Manoj points out, Azure does have a different programming model which you can take advantage to produce very robust applications. Azure also has the concept of Worker Roles, which are similar to Managed Services, in that they perform processing without a public interface. Instead, your web-roles take the requests, place them on the Queues, and the worker-roles then pick them up, process and send back responses.
It's a very powerful system, which I haven't fully explored, but the good news is that you don't have to be an immediate expert in the whole system, but can create simple ASP.Net sites as web-roles, deploy those then expand from there.
Have a go, it's well worth it

AppHarbor is a .NET Platform-as-a-Service. We can host your ASP.NET websites more or less un-modified and without the Visual Studio plugins and other crud that Windows Azure requires.
It depends on what type of cloud hosting are you looking for. There is some cloud hosting which will just give you space for application data like Amazon. While Azure gives you complete application framework which supports your application to be hosted in cloud. But programming in cloud is different programming paradigm than in traditional web form. You will have some limited classes from .Net framework available but better resources for scalability.
You cant directly use sql server in azure application. What you can use SqlAzure services.
Just referring a book which i feel would provide you the answer
