Utilizing CLB can be a great solution. The key is to clearly understand the use cases for this configuration. CLB works best when all servers to be load balanced reside in the Cloud. If dedicated servers need to be load balanced, or Cloud and Dedicated are to be load balanced together, you should deploy RackConnect with an F5 load balancer. The firewall used with RackConnect serves to further isolate and protect the
customers dedicated servers.
Also note that when using CLB with RackConnect, all internet traffic comes and goes through the Cloud, and the customer will pay for all outbound bandwidth at the standard CLB rate. This bandwidth is not included in the “included” bandwidth that comes with each dedicated server.
