bitcoin exchange server distribution

[Whynot8282]

Do bitcoin exchanges distribute their servers so that attacks can only harm part of distributed servers?

Yes popular exchanges do use off the shelf technology and content delivery networks. In any case, complete resistance
to ddos attack is difficult to guarantee. For this reason, and the subsequent lost access to funds in case an exchange is targeted,
we do not hold significant funds on any exchange without a very good reason.

is the tech hard to apply? I heard, first of all, it needs more servers. Does it mean, in AWS, do I need to have more than one EC2?

you seem to be going to open bitcoin exchange service yourself. I think its better contact network engineer who is experienced with this things.

Thanks for your reply.

Well is the shelf technology hard to achieve?

An exchange consists of mysql, bitcoind etc, and they are connected each other to run the exchange.

Could you please tell me how it works? The concept means MYSQL is installed in A server and Bitcoind is in B server. How to get them connected eachother?
