Cloud Computing, SOA and Windows Azure - Part 4

Hello World in Windows Azure

For a complete list of the co-authors and contributors, see the end of the article.

The following section demonstrates the creation of a simple "Hello World" service in a Windows Azure hosted application.

Note: If you are carrying out the upcoming steps with Visual Studio 2008, you will need to be in an elevated mode (such as Administrator). A convenient way of determining whether the mode setting is correct is to press the F5 key in order to enter debug mode. If you receive an error stating "the development fabric must be run elevated," then you will need to restart Visual Studio as an administrator.

Also, ensure the following on your SQL Express setup:

  • SQL Server Express Edition 2008 must be running under the ‘.\SQLEXPRESS' instance
  • Your Windows account must have a login in .\SQLEXPRESS
  • Your login account is a member of the sysadmin role

If SQL Express isn't configured properly, you will get a permissions error.

1. Create a Cloud Service Project
First you need to open the New Project window to create a new cloud service project using VB.NET or C# (see Figure 5).

Figure 5: The New Project window

2. Choose an ASP.NET Web Role
After you click OK on the New Project window, the New Cloud Service Project wizard will start. You will then see a window (see Figure 6) that will allow you to choose the type of role that you would like as part of your service deployment.

Figure 6: The New Cloud Service Project Window

Mainstream SOA design patterns and service-orientation principles can be applied to Windows Azure-hosted services very similarly to how they are applied to internal enterprise-hosted services. Furthermore, Windows Azure-hosted services support different service implementation mediums (such as Web services and REST services) and allow for the same service to be accessed via multiple protocols. This supports the creative application of specialized patterns, such as Concurrent Contracts [726] and Dual Protocols [739].

For the Hello World project, you will only need the ASP.NET Web Role type. Once you select this role, you can choose the role name.

3. Create the Solution
After clicking OK, the wizard will generate the solution, which you can then view using the Solution Explorer window (see Figure 7).

Figure 7: The HelloWorld solution structure displayed in the Solution Explorer window

4. Instantiate the Service
Now you can open the Default.aspx file using the Solution Explorer window, put "Hello, Cloud!" in the Body element and press F5 to run. You should see something like what is shown in Figure 8.

Figure 8: The HelloWorld service in action

This example was executed locally on IIS. If we were to deploy this service into the Windows Azure cloud, it would still be running in IIS because it is hosted in a Web role.

Summary of Key Points

  • The development environment for Windows Azure is fully integrated into Visual Studio, which provides a simulated runtime for Windows Azure for local desktop-based development and unit testing.
  • Creating and deploying cloud-based services with Windows Azure is simplified using available wizards and development UIs.

More and more brands have jumped on the IoT bandwagon. We have an excess of wearables – activity trackers, smartwatches, smart glasses and sneakers, and more that track seemingly endless datapoints.
