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.

Digital transformation is too big and important for our future success to not understand the rules that apply to it. The first three rules for winning in this age of hyper-digital transformation are: Advantages in speed, analytics and operational tempos must be captured by implementing an optimized information logistics system (OILS) Real-time operational tempos (IT, people and business processes) must be achieved Businesses that can "analyze data and act and with speed" will dominate those t...

I'm a lonely sensor. I spend all day telling the world how I'm feeling, but none of the other sensors seem to care. I want to be connected. I want to build relationships with other sensors to be more useful for my human. I want my human to understand that when my friends next door are too hot for a while, I'll soon be flaming. And when all my friends go outside without me, I may be left behind. Don't just log my data; use the relationship graph. In his session at @ThingsExpo, Ryan Boyd, Engi...

If you’re responsible for an application that depends on the data or functionality of various IoT endpoints – either sensors or devices – your brand reputation depends on the security, reliability, and compliance of its many integrated parts. If your application fails to deliver the expected business results, your customers and partners won't care if that failure stems from the code you developed or from a component that you integrated. What can you do to ensure that the endpoints work as expect...

According to Forrester Research, every business will become either a digital predator or digital prey by 2020. To avoid demise, organizations must rapidly create new sources of value in their end-to-end customer experiences. True digital predators also must break down information and process silos and extend digital transformation initiatives to empower employees with the digital resources needed to win, serve, and retain customers.

In this strange new world where more and more power is drawn from business technology, companies are effectively straddling two paths on the road to innovation and transformation into digital enterprises. The first path is the heritage trail – with “legacy” technology forming the background. Here, extant technologies are transformed by core IT teams to provide more API-driven approaches. Legacy systems can restrict companies that are transitioning into digital enterprises. To truly become a lea...
