1.3. Going Global

• Design your wide area network (WAN) architecture—Chapter 7.

• Follow three cardinal rules: scale, scale, and scale.

• Standardize server times on Greenwich Mean Time (GMT) to maximize log analysis capabilities.

• Make sure that your helpdesk really is 24/7. Look at ways to leverage SAs in other time zones—Chapter 13.

• Architect services to take account of long-distance links—usually lower bandwidth and less reliable—Chapter 5.

• Qualify applications for use over high-latency links—Section 5.1.2.

• Ensure that your security and permissions structures are still adequate under global operations.
