Application Request Routing for IIS7 is a proxy based routing module that forwards HTTP requests to content servers based on HTTP headers and server variables, and load balance algorithms.  Application Request Routing can be used to:

• Increase application availability and scalability.
• Better utilize content server resources.
• Facilitate application deployment including pilot management and A/B testing.
• Lower management costs and create opportunities for shared hosters.

Application Request Routing relies on URL rewrite module to inspect the incoming HTTP requests to make the routing decisions, and therefore, the URL rewrite module is required to enable Application Request Routing features.

Download the Modules:

• Microsoft URL Rewrite Module for IIS 7 (x86)
• Microsoft URL Rewrite Module for IIS 7 (x64)
• Microsoft Application Request Routing for IIS 7 (x86)
• Microsoft Application Request Routing for IIS 7 (x64)

Features:

• HTTP based routing decisions
  Unlike hardware load balancers that make the routing decisions at the IP level, Application Request Routing makes the routing decisions at the application level.  Working with URL rewrite module, powerful routing rules can be written based on HTTP headers and server variables.
• Load balance algorithms
  A user selected load balance algorithm is applied to determine which content server is most appropriate to service the HTTP requests.  Six algorithms are provided.
• Health monitoring
  Both live traffic and specific URL test are used to determine the health of content servers.  A set of configuration parameters are provided to define the meaning of server health.
• Client affinity
  Using a cookie, Application Request Routing can affinitize all requests from a client to a content server.  It differentiates the clients behind NAT, so each client is treated independently.  This feature requires that the clients accept cookies.
• Host name affinity
  “Host name affinity” is a specific feature for shared hosters. It changes the deployment topology to minimize and streamline administration and to create additional business opportunities.  For more information on this scenario refer to Overview of Shared Hosting Deployment Using Application Request Routing.
• Multiple server groups
  Application Request Routing can manage multiple server groups, which are logical groupings of content servers in an environment.  This feature allows Application Request Routing to be used in pilot management and A/B testing scenarios.
• Management and monitoring via UI
  All configuration settings and aggregated runtime statistics of Application Request Routing are managed and viewable via IIS Manager.
• Failed Request Tracing Rules
  Specific traces have been added to quickly troubleshoot and diagnose Application Request Routing.

Using the module:

These articles explain how to configure and achieve the core scenarios using Application Request Routing.  It is recommended that the articles are read in the following order as the scenarios get richer with each article:

• Install Application Request Routing
• Define and Configure an APplication Request Routing Server Group
• HTTP Load Balancing using Application Request Routing
• Configure 3-tier deployment architecture using Application Request Routing
• Pilot Program Management using Application Request Routing
• Shared Hosting using Application Request Routing
• Using Failed Request Tracing Routes to Troubleshoot Application Request Routing

The Patterns & Practices team has recently released the Composite Application Guidance for WPF which provides guidance for "componetizing" the development of enterprise-class WPF applications across multiple development teams, with each team owning a piece of the application, and then seamlessly integrating these pieces into one homogenous application.

Included in the guidance package is a reference implementation of WPF application, CFI Stock Trader, that models this guidance, reusable library code (called the Composite Application Library), documentation, quick start tutorials and hands-on labs.

You can download the bits here or to learn more about what the guidance entails, head on over to the developer center on MSDN.

I can't wait to try this stuff out!

Version 1.2 of the Visual Studio extensions for WSS has been released and available for download.  Version 1.2 provides support for Visual Studio 2008 in building SharePoint-based solutions.  The following tools are included:

Visual Studio 2008 Project Templates

• Web Part
• Team Site Definition
• Blank Site Definition
• List Definition
• Empty SharePoint Project

Visual Studio 2008 Item Templates

• Web Part
• Custom Field
• List Definition (with optional Event Receiver)
• Content Type (with optional Event Receiver)
• Module
• List Instance
• List Event Handler
• Template

SharePoint Solution Generator

Used to generate a Site Definition project from an existing SharePoint site.

Note here that this release only works for Visual Studio 2008.  If you're still doing development using Visual Studio 2005, you'll need to install Version 1.1 of VSeWSS which can be downloaded here.

Announced on the SharePoint Team Blog, the SharePoint Deployment Planning Services program has been launched and is geared at helping our Software Assurance (SA) customers sucessfully plan and deploy SharePoint Products & Technologies.  I think this program provides a great resource for those customers who are struggling to make sense of SharePoint technologies or are trying to uncover proven "best practices" around how to properly deploy and implement SharePoint-based solutions.

During my time as a Technology Architect within the Reston, VA Microsoft Technology Center, I worked with a number of customers in definining SharePoint-based solution architectures where we covered topics such as understanding SharePoint architecture, definining portal taxonomies and physical deployment topologies/architecture, development and integration opportunities through Strategy Briefings and Architecture Design Sessions as well as "real world" implementation through Proof of Concept engagements to demonstrate the capabilties of a "live" SharePoint solution.  It's certainly great to see these getting packaged into a set of service offerings that we can make more widely available to our customers and partners.

And speaking of partners, this program is jointly managed by our partner ecosystem as well as Microsoft Consulting Services which together provides proven business and technical expertise in architecting/deploying SharePoint-based solutions for small, medium, and large organizations alike.

To learn more about the SDPS program and what it can do for you, head over to the SDPS website.  Microsoft Partners having strong competency in the Microsoft Office System stack are encouraged to sign up and participate in this growing community.

Version 2.0 of the OBA Composition Reference Toolkit was released to the web today, on schedule and with all the great new features promised for the release. Version 1.0 of the toolkit was released at the Office Developer’s Conference in February 2008.

Watch the OBA Composition Reference Toolkit Overview Video to get an overview of the toolkit, the motivations for creating it, and its intended use. Visit the OBA Composition Reference Toolkit site to access and explore related resources: Installers for the toolkit & sample components, Documentation – architecture, user, admin, developer, and overview video.

What’s New in Version 2.0?

• IT administration capabilities integrated into the SharePoint Central Administration portal

Interesting eWeek report on the 100 Most Influential People in IT.

Zach Rosenfield (a Program Manager on the SharePoint Team) posted an announcment introducing the SharePoint Administration Toolkit.  This promises to be a great resource for administering your MOSS and WSS v3.0 deployments.  The initial version of the toolkit contains a couple of useful administrative tools, including the Batch Manager, which allows you to schedule bulk operations against site collections in a SharePoint farm, and a new command to the STSADM command-line utility called "updatealert" which will refresh all alert URLs in a specific site collection, which is important if you change the URL of a web application or after an upgrade.  A full whitepaper describing the toolkit can be found here.

Check out Zach's post of you want to have a good understanding of what the toolkit addresses and the features it contains.  The toolkit is available for download for both x86 and x64 SharePoint deployment configurations.

Enjoy!  I know I will!

I received an this e-mail this morning and I thought I'd share with the loyal readers of my blog.  Enjoy
