Web Technologies-II

Notes
Azure offers a computing environment already familiar to its developers who work with
the Microsoft Visual Studio 2008 Professional development system.
In August 2009, Advanced Telemetry began migrating its web-based presentation layer to
Windows Azure. The company also upgraded its web management portal for the middleware
using Microsoft Silverlight 2.0, a cross-browser implementation of the Microsoft .NET
Framework for building and delivering rich, interactive web applications.
Then Advanced Telemetry proceeded with the more complex middleware. In Windows
Azure, each application can have multiple instances. Each instance is assigned a virtual
machine (VM) that can run part or all of the application’s code. The company’s developers
can divide the application’s code into web roles (where it is necessary for the software to
accept and process Intelligent Terminal Transfer Protocol requests using Internet Information
Services, or IIS—a component of the Windows Server 2008 operating system) and worker roles
(which do not use IIS). The developers simply tell Windows Azure how many instances of
each role to run, and Windows Azure creates the VMs and provides built-in load balancing
to equalize requests coming into the application’s web role instances. “This capability is
important, because it allows us to do upgrades to various parts of the middleware without
touching the other parts,” says Naylor.
