There is one thing in common with all .COMs and their computing environments. This common item is UPTIME. In this type of scenario 99.997% up time is a cause for concern. Each minute that they are down, they are losing a potential customer to a competitor that might never come back to their site. The end-user in this case are all the cellular phone users across the USA who are using their WAP browsers to access this customer's website. So the problem for them is how to build an infrastructure that can withstand hardware failures, hackers etc. and still be up all of the time.

This virtual farm is created with a pair of F5's BigIp Load Balancers. To the customer, they browse the virtual IP address of the farm and the Load Balancer distributes the load among the pool of web servers. Each Server will have two redundant power supplies. Multiple Network Interfaces are bound together in case of hardware failure. This allows their customer traffic to be balanced among multiple facilities and protects against the failure of any one facility.
