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  and Dual Protocols .
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.

The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs. In this Power Panel at 15th Cloud Expo (http://www.CloudComputingExpo.com...

What do a firewall and a fortress have in common? They are no longer strong enough to protect the valuables housed inside. Like the walls of an old fortress, the cracks in the firewall are allowing the bad guys to slip in - unannounced and unnoticed. By the time these thieves get in, the damage is already done and the network is already compromised. Intellectual property is easily slipped out the back door leaving no trace of forced entry. If we want to reign in on these cybercriminals, it's hig...

Fundamentally, SDN is still mostly about network plumbing. While plumbing may be useful to tinker with, what you can do with your plumbing is far more intriguing. A rigid interpretation of SDN confines it to Layers 2 and 3, and that's reasonable. But SDN opens opportunities for novel constructions in Layers 4 to 7 that solve real operational problems in data centers. "Data center," in fact, might become anachronistic - data is everywhere, constantly on the move, seemingly always overflowing. Net...
