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.
