IIS 6 Today: A Proven Platform
• Proven Scalability
• MySpace - 23 Billion Page* Views/Month
• Microsoft.com - 10k Req/sec & 300K Connections
• Match.com 30 million page view daily
• Proven Security
• No critical IIS 6 hotfixes since RTM*
• Proven Trust
• 54% of Fortune 1000 use IIS (port80software.com)
• A solid foundation to build on.
*(as of Nov 28th 2006)
Internet Information Services (IIS) 7.0
More than a Web server, Internet Information Services 7.0 provides an
accessible, extensible platform for developing and reliably hosting Web
applications and services.

Modular Design
• Modular Pipeline
•
Features are provided in discrete modules
•
Remove or replace modules as you see fit
•
•
•
Reduce security exposure
Reduce memory footprint
Increase performance
• Add Custom Modules in native or manage code
•
•
•
Leverage the power of .NET for all content
Integrate with specialized infrastructure
Easily incorporate new technologies
• Modular UI
• Add custom pages to UI (Winforms)
• Integrate Application configuration with IIS

IIS 7 Modularity
Extensibility
• IIS 6
•
•
•
•
IIS 6 extensibility limited to ISAPI filter and extensions
UI modifications in MMC are challenging
Difficult to extend IIS 6 Schema
Web service activation using http only
• IIS 7
•
•
•
•
•
Custom native or manage code modules and handlers
Easy to add your apps to UI
Simple to extend IIS 7 schema
Instrument apps to integrate with IIS 7 tracing
Host web services using non-http protocols
IIS 7 Extensibility
.NET Integration
• Simplifies security and administration
• Leverage the power of .NET for all content
with managed global modules
•
•
•
•
Forms Authentication
URL Authorization
.NET Caching
.NET Role and Membership Providers
• New APIs manage both IIS 7 and .NET
• Enables Xcopy deployment scenarios
IIS6 ASP.NET Integration
• Runtime limitations
• Only sees ASP.NET
requests
• Feature duplication

Management Tools
GUI

Script
Managed Code
IIS Manager
appcmd
WMI (root\WebAdministration)
Microsoft.Web.Administration
• Manage IIS and ASP.NET
• View enhanced runtime data
•
worker processes, appdomains, executing requests
• Manage delegation
• Use whichever management tool suits your needs…
• Note: Powershell has recently been added to the tools you
can use! See http://iis.net for details
Coding:
Microsoft.Web.Administration
New APIs enable developers to write tools to deploy,
manage, and troubleshoot ASP.NET and IIS
ServerManager iisManager = new ServerManager();
foreach(WorkerProcess w3wp in iisManager.WorkerProcesses) {
Console.WriteLine("W3WP ({0})", w3wp.ProcessId);
foreach(Request request in w3wp.GetRequests(0)) {
Console.WriteLine("{0} - {1},{2},{3}",
request.Url,
request.ClientIPAddr,
request.TimeElapsed,
request.TimeInState);
}
}
IIS 7 Management
Rapid Troubleshooting with
Failed Request Tracing
• Significantly reduce need for “crash dump
analysis”
• Configure custom failure definitions per URL
• Time taken
•
“Write Trace log for 200 (ok) response taking over 15 seconds
• HTTP Status/substatus codes
•
“Write Trace log when you see a 500 error for Invoice.aspx”
• Error level
• Manage with UI, WMI, API, Appcmd
• Instrument applications with custom trace event
Failed Request Tracing
Hosting Web Services in IIS 7
• Windows Communication Foundation (WCF) is
part of .NET 3.0
• IIS 7 will host web service in worker process
• Health of worker process is managed by Web
Activation Service (WAS)
• Provides “external” monitoring and recycling
• Activate over TCP, Named Pipe, MSMQ, or HTTP
• Web Service can share state with an ASP.net
application
• Provides high availability, managed process for
web service based applications
Web Service Activation
Summary
• Custom modules and handlers
• Create new IIS 7 modules for the public
• Provide solutions for customers with unique
requirements (ie. Custom authentication, auditing …)
• Extend reach of existing .NET handlers and modules to
non ASP.NET content
• Quickly integrate new technologies
•
•
•
•
•
Extend UI / Schema: integrated administration
Deploy using new APIs
Manage with delegated administration
Diagnose with built in / extensible tracing
Provide high availability host for web services
