Transcript

  • 1. Chapter 15: Networking Services Design Optimization
    • Essential Networking Services Optimization
    • Data Protection and Optimization
    • Advanced Design Optimization
  • 2. Optimizing Designs for Applications
    • Identify which networking services the applications require.
    • Select the best placement for servers running networking services.
    • Select optimal specifications of the networking services.
  • 3. Identifying Required Networking Services
  • 4. Selecting the Best Server Placement
    • Determine placement of servers running networking services.
    • Choose from the following options:
      • Place on the same server.
      • Place on the same network segment.
      • Place on an adjacent network segment.
  • 5. Selecting the Optimal Networking Services Configuration
    • Base the configuration on organizational requirements and constraints.
    • Consider that some requirements and constraints may conflict.
    • Resolve conflicts by
      • Prioritizing the requirements
      • Tailoring the design to achieve the highest priority
      • Prioritizing the remaining requirements
  • 6. Optimizing Designs to Reduce the Number of Servers
    • Lowers deployment cost
    • Lowers long-term costs
    • Allows you to combine services on one server
      • Services use unique Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) port numbers.
      • Security requirements allow combined services.
      • Availability requirements allow combined services.
      • System resources support multiple networking services with acceptable performance.
  • 7. Identifying Security Requirements and Constraints
    • Consider security requirements when optimizing servers accessed by
      • Authorized users only
      • Unauthorized users only
      • A combination of authorized and unauthorized users
  • 8. Selecting Security Optimization Methods
    • Methods must not compromise security requirements.
    • Place services on the same segment/server as applications.
    • Combine networking services on one server.
    • Isolate networking services on separate servers.
  • 9. Optimizing by Using Windows Clusters
    • Optimize by combining services on clusters to improve availability and performance.
    • Choose from the two cluster types:
      • Network Load Balancing clusters
      • Server clusters
  • 10. Network Load Balancing Clusters
    • Two or more combined Microsoft Windows 2000 servers that
      • Provide load balancing and fault tolerance
      • Offer an alternative to round robin DNS
      • Can use the “share nothing” model
  • 11. Server Clusters
    • Two or more combined Windows 2000 servers that
      • Share common disk resources
      • Can be configured for fault tolerance and load balancing
      • Provide automatic failover
      • Minimize recovery time
  • 12. Optimizing the Windows 2000 Configuration
    • Include only signed device drivers.
    • Run only reliable services or applications.
    • Run only the required services or applications.
    • Avoid combining networking services that compete for resources.
  • 13. Optimizing to Reduce Network Traffic
    • Reduce network traffic to improve performance.
    • Combine networking services on the same computer.
    • Place servers running networking services on the same or adjacent network segment.
  • 14. Chapter Summary
    • Evaluate the requirements and constraints to plan design optimization.
    • Prioritize requirements to avoid conflicts.
    • Use Windows Clustering to improve availability and performance.
      • Network Load Balancing clusters
      • Server clusters
    • Include reliable and certified software components.
