Akamai’s Global Traffic Manager, or GTM for short, is technology that allows a user to configure traffic to be sent to more than one data center, or at least more than one origin URL. For an Akamai primer, go here<\/a>.<\/p>\n

In our case, we used it to facilitate A-B testing. <\/p>\n

We could have accomplished the same thing with any smart load balancer than handles DNS load balancing, such as the F5 GTM.<\/p>\n

We configured Akamai’s GTM to point 50% of our traffic to origin address A, and 50% to origin address B. We then configured our internal F5 LTM to direct requests for origin address A to our servers that hosted code base A, and requests to origin address B to servers that hosted code base B.<\/p>\n

As noted, we could have run the GTM piece in our F5 GTM. Technically, we could have done the entire thing in the LTM. If the user didn’t have a cookie, we would randomly distribute the initial request to one of two servers. The software then sets a cookie, and subsequent requests are persisted based on either:<\/p>\n

1) an existing mapping of that session to a backend server if the session has not expired
\n2) or to one of the two pools based on the cookie the last time the user visited<\/p>\n

However, as soon as we would like to span data centers, we are back to needing a GTM in some form or fashion.<\/p>\n

We configured the Akamai GTM by clicking through the screens shown below.<\/p>\n
