Nginx provides a fast and lightweight solution that enables Global Traffic Management. GTM or GSLB is a technique used to direct browsers to faster local copies of the same web content, by using the source IP to identify the geographical location of the user. Detailed installation and setup instructions are available in issue 6 of o3 magazine, a free open source / business digital magazine. The magazine is showcasing the solution, as it is hosted on a Content Delivery Network using the very same solution. Using F5 or another vendor, would have cost the magazine approximately US$250,000, instead of two weekends to configure and test the solution."
