> Searched but found nothing, proxies(cluster) are just for one central point, for instance for different available zones, to gather metric data delegating Zabbix Server, however on the Zabbix server side, only one instance of Zabbix server(failover or primary-backup mode) I’m afraid it’s not enough for all of them to serve API requests or trigger alerts. So is it possible to have an active-active cluster of Zabbix server, any potential risks/problems exist, just for one purpose - one or more Zabbix Server down then nothing effected but only the performance.

I found a thread from 2012:
https://www.zabbix.com/forum/showthread.php?t=25349

"Large" installations in that thread are over 5k hosts, and I get the 
impression that people are hitting the upper limit of Zabbix (or rather, 
the database) with that number. Of course, that's 5 years old so 
software and hardware have evolved. But millions of hosts? I doubt it...
