Explaining The Cloud


Published on

This is an academic presentation that discusses as a philosophical level the transformation that IT is experiencing in relation to cloud computing. There is some emphasis and examples around Microsoft's implementation of Windows Azure, but the principles are reflected in most cloud platforms today.

This presentation is ideal to initiate students, academics, IT Managers, and CIOs on the implications of Cloud computing.

  • Windows Azure runs on a large number of machines, all located in Microsoft data centers and accessible via the Internet. A common Windows Azure fabric knits this plethora of processing power into a unified whole. Windows Azure compute and storage services are built on top of this fabric. The Windows Azure compute service is based, of course, on Windows. For the initial availability of this service, a Community Technology Preview (CTP) made public in the fall of 2008, Microsoft allowed Windows Azure to run only applications built on the .NET Framework. The company has announced plans to support unmanaged code as well, i.e., applications that aren’t built on the .NET Framework, on Windows Azure in 2009. In the CTP version of Windows Azure, developers can create .NET-based software such as ASP.NET applications and Windows Communication Foundation (WCF) services. To do this, they can use C# and other .NET languages, along with traditional development tools such as Visual Studio 2008. And while many developers are likely to use this initial version of Windows Azure to create Web applications, the platform also supports background processes that run independently—it’s not solely a Web platform. Both Windows Azure applications and on-premises applications can access the Windows Azure storage service, and both do it in the same way: using a RESTful approach. The underlying data store is not Microsoft SQL Server, however. In fact, Windows Azure storage isn’t a relational system, and its query language isn’t SQL. Because it’s primarily designed to support applications built on Windows Azure, it provides simpler, more scalable kinds of storage. Accordingly, it allows storing binary large objects (blobs), provides queues for communication between components of Windows Azure applications, and even offers a form of tables with a straightforward query language. Running applications and storing their data in the cloud can have clear benefits. Rather than buying, installing, and operating its own systems, for example, an organization can rely on a cloud provider to do this for them. Also, customers pay just for the computing and storage they use, rather than maintaining a large set of servers only for peak loads. And if they’re written correctly, applications can scale easily, taking advantage of the enormous data centers that cloud providers offer. Yet achieving these benefits requires effective management. In Windows Azure, each application has a configuration file. By changing the information in this file manually or programmatically, an application’s owner can control various aspects of its behavior, such as setting the number of instances that Windows Azure should run. The Windows Azure fabric monitors the application to maintain this desired state. To let its customers create, configure, and monitor applications, Windows Azure provides a browser-accessible portal. A customer provides a Windows Live ID, then chooses whether to create a hosting account for running applications, a storage account for storing data, or both. An application is free to charge its customers in any way it likes: subscriptions, per-use fees, or anything else. Windows Azure is a general platform that can be used in various scenarios.
