i have a DNS server running on ubuntu 14.04 - bind9 , because the server is hosted on t2 micro amazon free tier i don't think it can handle all requests that it will get , over 10000+ clients will use my DNS server ..
so i was thinking of some sort of Load-Balancing like running another instance and setup a round-robin or something on the main DNS to load-balance requests between him and the second instance ..
how to do that ?! ( i guess you get the idea of what i want to do any solution will work )
