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.

Fact is, enterprises have significant legacy voice infrastructure that’s costly to replace with pure IP solutions. How can we bring this analog infrastructure into our shiny new cloud applications? There are proven methods to bind both legacy voice applications and traditional PSTN audio into cloud-based applications and services at a carrier scale. Some of the most successful implementations leverage WebRTC, WebSockets, SIP and other open source technologies. In his session at @ThingsExpo, Da...

Today we can collect lots and lots of performance data. We build beautiful dashboards and even have fancy query languages to access and transform the data. Still performance data is a secret language only a couple of people understand. The more business becomes digital the more stakeholders are interested in this data including how it relates to business. Some of these people have never used a monitoring tool before. They have a question on their mind like “How is my application doing” but no id...

Information technology is an industry that has always experienced change, and the dramatic change sweeping across the industry today could not be truthfully described as the first time we've seen such widespread change impacting customer investments. However, the rate of the change, and the potential outcomes from today's digital transformation has the distinct potential to separate the industry into two camps: Organizations that see the change coming, embrace it, and successful leverage it; and...

The Internet of Things (IoT) promises to simplify and streamline our lives by automating routine tasks that distract us from our goals. This promise is based on the ubiquitous deployment of smart, connected devices that link everything from industrial control systems to automobiles to refrigerators. Unfortunately, comparatively few of the devices currently deployed have been developed with an eye toward security, and as the DDoS attacks of late October 2016 have demonstrated, this oversight can ...

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. However, most consumers have no idea what “IoT” means. Creating more wearables that track data shouldn't be the aim of brands; delivering meaningful, tangible relevance to their users should be. We're in a period in which the IoT pendulum is still swinging. Initially, it swung toward "smart for smar...

We are always online. We access our data, our finances, work, and various services on the Internet. But we live in a congested world of information in which the roads were built two decades ago. The quest for better, faster Internet routing has been around for a decade, but nobody solved this problem. We’ve seen band-aid approaches like CDNs that attack a niche's slice of static content part of the Internet, but that’s it. It does not address the dynamic services-based Internet of today. It does...
