Bob Carver MCSE+I,MCT Senior Instructor ARIS Corporation How to set up a reliable web server using Internet Information Server 5.0 and Windows 2000

Session Prerequisites  This session assumes that you understand the fundamentals of:  Basic knowledge of Internet Information Server  This is a level 200 session

What You Will Learn Today  Configuration options for process management in IIS 5.0 and when to use them  How to configure your web server to recover automatically  How to use logging and application accounting to tune your web server for optimum reliability

How Apps Crash IIS 4.0 Web Service Failure!!!! In Process (INETINFO) Application Out of Process Application 1 Out of Process Application 2

Demonstration Running Applications In And Out Of Process In IIS 4.0

Enhancements and New Process Management Options in IIS 5.0  Out of process no longer a big performance penalty  Only one good reason to run apps in process  A new option, pooled out of process allows IIS 5.0 to scale

Pooled out of Process Application 2 In Process (INETINFO ) Application 1 Application 3 Application Out of Process Application 1 Application Out of Process Application 2 Pooled Out Of Process Pooled out of Process Application 1 Application 2 Application 3 Web Service Still Working!!!

 In process  Out of process  Pooled out of process Demonstration: Configuring Process Management in IIS 5.0

Memory Consumption

Performance

Defaults, Tips, and Tricks  Quiz  When should an app run in process?  How does IIS 5.0 handle applications by default?  The default gives you the best protection/performance/scalability tradeoff  Run mission critical apps out of process isolated to insulate them from other apps

Questions?

What Options Do You Have If The Web Server Crashes?  Issues with IIS 4.0  Stopping all services in INETINFO not intuitive  No consistent way to force a shutdown remotely  Graceful shutdown takes too long  Killing IIS not obvious to admins (not in GUI, have to use Resource Kit)  IIS doesn’t recover automatically from crashes

New Restart Options In IIS 5.0  Reliable Restart: IIS automatically recovers  Restarts IIS if INETINFO crashes  Graceful shutdown is faster in all cases  Graceful shutdown is tried first, then kill!  Multiple configuration Options  MMC (GUI) support for novice admins  Command line support for experts, scheduled restarts etc.  Secure remote restart

Demonstration How To Configure Reliable Restart In IIS 5.0

Defaults, Tips, and Tricks  Defaults to automatic restart  Run nothing in process  Run most applications in pool  If your application is mission critical, run it out of process  Add IISRESET to scripts executed by monitoring software

Questions?

How To Make IIS 5.0 Work Smarter and More Reliably For You  Logging in IIS 5.0  How to turn it on  What to log  Where to find the logs  What to look at

Demonstration How To Enable IIS Logging, And Retrieve The Data

Optimizing Your Web Server  Application Accounting: A New Option  Thread Gating: Giving threads to the applications that need them  Process Throttling: CPU Quotas to keep applications from hogging resources

Thread Gating  Takes idle threads from an application that isn’t using them and gives them to an app that needs them.  Done automatically by IIS based on a variety of factors

Process Throttling  Keeps CGI and Out Of Process apps from hogging resources  Helpful on multi-site servers  Three phases  100 % Log Event  150% Reduce Thread Priority  200% Stop all Out of Process Apps  Enabled at the Web Site level  In Process and Pools not affected

Demonstration How To Optimize IIS 5.0 For Reliability Using Application Accounting

Defaults, Tips, and Tricks  Turn on process accounting logs  Remember the limitations of Process Throttling  Enabled at Site level  Only Out of Process can be throttled  %CPU usage over time can be tricky  Review logs regularly – find problems before impact you

Questions?

Scenarios  Small Business  Remote admin requires less support staff  Reliable restart means less after-hours support  Medium Business  Process pools provide better scalability with less hardware  Reliable restart may reduce the need for WLBS  Large Business  Thread Gating and Process Throttling enables faster and safer multi-site hosting  Process Accounting helps you find problematic applications

Case Studies Lessons learned from the real world  They will be coming!  Microsoft working with many large clients, and have many lessons learned.  Case studies will be coming, look for them on

Other Resources  IIS Resource Kit  Web Stress Application (Homer)  NT Resource Kit  Kill  TList  Windows Load Balancing Server  NT Enterprise  Windows 2000 Advanced Server  Windows 2000 Data Center

Y2K Status & Strategy  Windows NT 4 Service Pack 5 (8/12/99)  English: 3 Known Y2K issues (NNTP, BIOS Update, and Outlook Express)  Non-English: Same issues as above  All versions compliant pending software updates  See: duct/product.asp  Windows 2000 Advanced Server  See the above site after release
