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).

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.

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 word—or rather, the contraction—is simple: DevOps. But DevOps, which refers to the increased communication and collaboration between development and IT operations, is an ever-changing, sometimes complicated term. While “dev” and “ops” used to be siloed into separate philosophies, practices, tools, and work flows, they’re merging into one. The result? A more efficient, reliable process and product.
In his General Session at 16th Cloud Expo, David Shacochis, host of The Hybrid IT Files podcast and Vice President at CenturyLink, investigated three key trends of the “gigabit economy" though the story of a Fortune 500 communications company in transformation. Narrating how multi-modal hybrid IT, service automation, and agile delivery all intersect, he will cover the role of storytelling and empathy in achieving strategic alignment between the enterprise and its information technology.
In today's enterprise, digital transformation represents organizational change even more so than technology change, as customer preferences and behavior drive end-to-end transformation across lines of business as well as IT. To capitalize on the ubiquitous disruption driving this transformation, companies must be able to innovate at an increasingly rapid pace. Traditional approaches for driving innovation are now woefully inadequate for keeping up with the breadth of disruption and change facing...

Software delivery was once specific to the IT industry. Now, Continuous Delivery pipelines are used around world from e-commerce to airline software. Building a software delivery pipeline once involved hours of scripting and manual steps–a process that’s painful, if not impossible, to scale. However Continuous Delivery with Application Release Automation tools offers a scripting-free, automated experience. Continuous Delivery pipelines are immensely powerful for the modern enterprise, boosting ...
Containers have changed the mind of IT in DevOps. They enable developers to work with dev, test, stage and production environments identically. Containers provide the right abstraction for microservices and many cloud platforms have integrated them into deployment pipelines. DevOps and containers together help companies achieve their business goals faster and more effectively. In his session at DevOps Summit, Ruslan Synytsky, CEO and Co-founder of Jelastic, reviewed the current landscape of Dev...
DevOps is being widely accepted (if not fully adopted) as essential in enterprise IT. But as Enterprise DevOps gains maturity, expands scope, and increases velocity, the need for data-driven decisions across teams becomes more acute. DevOps teams in any modern business must wrangle the ‘digital exhaust’ from the delivery toolchain, "pervasive" and "cognitive" computing, APIs and services, mobile devices and applications, the Internet of Things, and now even blockchain. In this power panel at @...

"It is not necessary to change. Survival is not mandatory." – W. Edwards Deming. How often do we see this quote used in DevOps blogs without a hint of irony? It’s as if we need to instantly complete generations of evolution to stave off extinction, like trying to grow an extra lung overnight. DevOps or Die!!! So this is it – the dreaded DevOps transformation looms large. The department will be ‘shaken up’, practices will be ‘turned on their head’, and staff will be ‘taken out of their comfort zo...

Adding public cloud resources to an existing application can be a daunting process. The tools that you currently use to manage the software and hardware outside the cloud aren’t always the best tools to efficiently grow into the cloud. All of the major configuration management tools have cloud orchestration plugins that can be leveraged, but there are also cloud-native tools that can dramatically improve the efficiency of managing your application lifecycle. In his session at 18th Cloud Expo, ...

In his session at 20th Cloud Expo, John Jelinek IV, a web developer at Linux Academy, will discuss why major players like AWS, Microsoft Azure, IBM Bluemix, and Google Cloud Platform are all trying to sidestep VMs and containers...
We call it DevOps but much of the time there’s a lot more discussion about the needs and concerns of developers than there is about other groups. There’s a focus on improved and less isolated developer workflows. There are many discussions around collaboration, continuous integration and delivery, issue tracking, source code control, code review, IDEs, and xPaaS – and all the tools that enable those things. Changes in developer practices may come up – such as developers taking ownership of code ...
