I have multiple nginx machines running and proxy LB through a round  
robin  
DNS mechanism.

I do rate limiting as follows

limit\_req\_zone $binary\_remote\_addr zone=pw:30m rate=20r/m;

```
    location / {

                limit_req zone=pw burst=5 nodelay;

```

But this is per machine. Can this data be shared between the load  
balancers  
so that rate limiting is global and I can scale out.

Correction:

I have multiple nginx machines running proxy and LB’s through a round  
robin  
DNS mechanism.

There is no good solution. Simpliest one is to just use  
per-frontend limits.
