The design you propose is stateful, and if you read the chapter closely, you can see we spend a lot of effort to make things stateless.

The main thing I wanted to respond to in this thread about a single bad server destroying your yearly SLO is described in the first paragraph in the section on load balancing at the virtual IP address.

Sorry I couldn't find a clear rationale in the link. Why does Google prefer a stateless load balancer? Is it infeasible to maintain state at that scale?

Sorry, I didn't read the document that closely. It was a bit too long.

Overall, virtual IPs are still an interesting solution.
