Overview

The Enterprise Library Integration Pack for Windows Azure extends Microsoft Enterprise Library 5.0 to add additional support for developing and managing Windows Azure applications. It shares the same benefits as Enterprise Library and helps developers achieve the same goals.

The Enterprise Library Integration Pack for Windows Azure is a major release, and it contains many compelling new features and updates that will make Windows Azure developers and system administrators more productive:

  • Two new application blocks:
    • The Autoscaling Application Block to help you to automatically scale your Windows Azure applications.
    • The Transient Fault Handling Application Block to help you make your Windows Azure applications more resilient when they encounter transient fault conditions.
  • The Blob configuration source to load configuration information from a blob into your Azure Storage account so that you can modify it without having to redeploy your application to Windows Azure.
  • Windows PowerShell cmdlets to browse and manipulate the Autoscaling Application Block settings directly from Windows PowerShell.
  • Protected configuration provider to allow you to encrypt sections of your configuration files in Windows Azure.
  • Updated database creation scripts so that you can migrate your code using the database trace listeners of the Logging Application Block and the Caching Application Block.
  • Learning resources to help you ramp up quickly, including:
    • Reference Documentation
    • Developer's Guide
    • Reference Implementation that illustrates the use of the application blocks

The Enterprise Library Integration Pack for Windows Azure is one of several existing and planned integration packs for Enterprise Library.

Common Scenarios

The Integration Pack addresses the following high-level scenarios:

  1. Autoscaling both web and worker roles in Windows Azure by dynamically changing instance counts or performing throttling.
  2. Autoscaling Windows Azure roles based on timetables.
  3. Autoscaling Windows Azure roles based on metrics collected from the application and/or Windows Azure but constrained by upper and lower bounds on the instance count per role.
  4. Managing the autoscaler configuration by using Windows PowerShell.
  5. Making Windows Azure applications resilient to transient errors when they are using these cloud services: SQL Azure, Windows Azure Storage, Windows Azure Caching, and Windows Azure Service Bus.
  6. Storing Enterprise Library configuration settings in Windows Azure blob storage.
  7. Storing Enterprise Library configuration settings securely.

Audience Requirements

These reusable components and guidance are intended primarily for software developers and software architects developing Windows Azure enterprise applications as well as IT professionals and system administrators managing these applications. To get the greatest benefit from this guidance, developers and architects should have an understanding of the following technologies:

  • Windows Azure
  • Microsoft Visual C# or Microsoft Visual Basic
  • Microsoft .NET Framework

Familiarity with Enterprise Library will help but is not required.

Contents of This Release

Microsoft Enterprise Library 5.0 Integration Pack for Windows Azure contains the following:

  • Binaries (pre-compiled, strong-named assemblies for all the source code)
  • Source code
  • Symbols for debugging
  • Unit tests
  • Documentation

System Requirements

For the application blocks:

  • Operating systems: Windows 7 Professional or higher, 32-bit and 64-bit; Windows Server 2008 R2 or Windows Server 2008.
  • Windows Azure Tools for Visual Studio and Windows Azure SDK v1.6 (all-in-one installer can be found at http://www.microsoft.com/windowsazure/sdk).
  • Additionally, in order to run unit tests, Moq is required (v4.0 or later). It will be installed automatically if you install the Enterprise Library Integration Pack for Windows Azure Source package via NuGet.
  • Optionally, in order to use the Logging Application Block Logger, the Microsoft Enterprise Library 5.0 Logging Application Block is required (available via NuGet or as an MSDN download).

For the Windows PowerShell cmdlets:

  • Operating systems: Windows 7 Professional or higher, 32-bit and 64-bit; Windows Server 2008 R2 or Windows Server 2008; Windows PowerShell cmdlets have also been tested on Windows Server 2003.

For the Tailspin Surveys sample application:

  • Run the dependency checker and follow the instructions from the Tailspin Surveys installation guide (in the Developer's Guide).
  • The Reference Implementation has been tested on Windows 7 Professional 32-bit and 64-bit and on the Windows Server 2008 R2 platforms. It will likely work on other platforms if you satisfy the prerequisites identified by the dependency checker, but those have not been included in the test matrix.

For a rich development environment, the following is recommended:

  • Microsoft Visual Studio 2010 Service Pack 1.

Getting Started

For information about getting started with Enterprise Library, see the Enterprise Library reference documentation and the Developer's Guide.
