You'd need at least a load balanced pair of servers serving results to your application. In theory, if you have enough RAM, you could run them on the same machine, although you'd lose some redundancy that way. I guess another way is to borrow and temporarily cut over to another system and then cut back, but I'd really recommend having two full time systems if you want to preserve uptime overall.
