server - Tomcat manual load balancing: multiple domains or single one -


i hope questione doesn't sound trivial.

we develop web application in saas style deployed tomcat instance. in same virtual machine installed both db server app , tomcat. db in multitenant configuration, same schema replicated each our our customers, preserve data integrity.

we thinking of splitting configuration installing virtual machine divide number of customers between 2 machine instead of one, reducing problems half of our customers in case 1 of machine out maintenance , better distribute resources; sort of manual load balancing.

the problem if should buy domain new server , new customers (we insert new customers in new server) should type www.myapp2.com instead of old www.myapp.com , sounds ugly.

i took time sketch simple graph:

enter image description here

maybe can resolved server responding @ www.myapp.com manage login data , redirect user 1 of 2 servers.

or maybe messing , should investigate in proper load balancing solution proxy(not manual).

what best approach in modern industry?

thanks
