Exchange 2000 Webstore Strategies

Three factors determine how an application is configured on the server and whether a new server is required: security, risk and availability. The worksheet in Figure 2 provides a good start in identifying each variable.

Figure 2: Application worksheet

Connectivity Requirements (This determines if a MAPI store is required)

• Does the proposed application require:
  
• Outlook 97 or Outlook 98 Access?
  
• Offline Access?
  

WAN Impact (This will determine if replication traffic and remote traffic be analyzed)

• Are the users (mostly) centralized to a single data center? Specify.
  
• Are the users (somewhat) equally divided among the data centers (Global Access)
  
• What is the projected daily traffic for the application? (Better phrasing required)
  
• What is the expected population for the first six months?
  
  • Less than 500 users
    
  • 500-1000 users
    
  • 1,000-10,000 users
    
  • More than 10,000 users
    

Application Requirements

• Does this application require:
  
  • Custom Sinks or agents?
    
  • Integration with Chat?
    
  • Integration with Conferencing? (Exchange conferencing server)
    
  • Integration with other applications (Databases or systems)
    
  • Additional security above and beyond the Secure ID and Kerberos
    
    • Extreme Physical Security
      
      • Cannot be located in Data Center
        
      • Cannot be on same machine as other databases
        
      • Administered by department
        
      • Cannot be accessed by Internal system
        
    • Specialized Departmental Management tools or access

Schema Requirements

• Does this application require:
  
  • Active Directory Schema update or expansion?
    
  • Web store Schema sharing?
    
  • Extreme protection from schema inheritance?
    

Recoverability

• What is the required uptime for the application (affects the price of the app)
  

A. 99.999

B. High Availability with a 4 Hour recovery window

C. High Availability with a 8 Hour recovery window

D. High Availability with no guarantees

Management and Monitoring (NetIQ and Provisioning server may offer some relief)

• Does this application have any specific monitoring requirements?
