How Do You Distribute Traffic to Web Servers without a Load Balancer?

Problem scenario
You want to direct traffic to web servers (e.g., duplicative, stateless web servers). You want to do it without a load balancer (as they can become a bottleneck). What technologies could you use?

Possible Solution #1
Use Round Robin DNS. This DNS system can send traffic to a list of web servers. See more on

Possible Solution #2
Use Anycast.

In anycast, a collection of servers share the same IP address and send data from a source computer to the server that is topographically the closest.

Anycast is one-to-one routing mechanism (unlike a broadcast system).

[W]ith Anycast there are multiple possible destinations and the network itself picks the route that is most preferential.
