F5 BigIP Load Balancing

Every GoGrid account includes FREE hardware F5 load balancing. It takes less than 5 minutes to setup F5 load balancing and the process is completely automated. Three Virtual IP (VIP) addresses are included and additional VIPs can be purchased for $19.99/month per VIP. A VIP is the IP address the F5 load balancer uses to direct traffic to servers.

F5 Load balancing can be used to spread internet traffic across two or more servers. In the event a server crashes, the load balancer will redirect all traffic to the remaining online servers preventing application downtime. If your web application sees a drastic increase in internet traffic adding additional servers to the load balancer is simple and ensures your servers will not crash due to an overload of incoming HTTP requests.

The following load balancing algorithms and persistence settings are supported:

Round Robin
Sticky Session
SSL Least Connect
Source address
