Internet Information Server

• Scaling In and Out
• Tuning the Server
• Tuning the Application Layer
• Optimizing Scripting

6
Scale In and Out

• Can use more processors, memory, etc. with
  Windows 2000
• Use a tiered architecture
• Separates workloads
• Structure based on applications and services in
  use (I.e. static tier, application tier,
  database tier, and authentication tier)
• Network segmentation between tiers

7
Scaling Out

• DNS Round Robin
• Svr1, Srv2, Svr1.
• No Fault Tolerance
• Network Load Balancing (NLB)
• Round Robin
• Adjusts for Additions and Failures
• 3rd Party
• Cisco Local Director, etc

• Requires more memory
• Activate Process Accounting
• Consult Microsofts 25 ASP Tips to Improve
  Performance and Style

10
Stress Testing

• Use System Monitor to monitor and examine
  processor, memory, disk subsystem, and network
  subsystem
• HTTP Monitoring Tool
