Hello everyone. I've recently experienced a great deal of growth with my website. I am getting quite a bit of traffic and generally doing quite well. My major worry now is what would happen to my business if my webserver either crashed or received too much traffic to handle in a graceful manner.
What options are available to spread the traffic of a single website across multiple webservers? What about across multiple webservers at different ISPs? How do the big players handle this? How would you do it?
