3. 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. IIS 7.0 Enhancements Reduced Attack Surface Create Streamlined Servers Rapid Application Deployment Extend/Modify IIS Features Fast Diagnostics Modular Architecture Extensible Design Integrated with.NET ManageableManageable Built in Request Tracing

4. 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

8. 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

9. IIS 7 Extensibility

10. .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

13. IIS 7.NET Integration

14. Management Tools 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 detailshttp://iis.net GUI Command Line Script Managed Code IIS Manager appcmd WMI (root\WebAdministration) Microsoft.Web.Administration

15. Coding: Microsoft.Web.Administration 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); } } New APIs enable developers to write tools to deploy, manage, and troubleshoot ASP.NET and IIS

16. IIS 7 Management

17. 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

18. Failed Request Tracing

19. 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

20. Web Service Activation

21. 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
