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