How to organize ddos protection?

Good afternoon.
The site only during the development phase and we would like to protect yourself from possible ddos attacks.
Know about CloudFlare, but I saw info, that RCN is blocking their IP. How true this is and whether or not to connect?
How to protect from ddos to my server front, nginx, backend API node.js
Heard about IPtables, they do their job?
What are the options? As do giants like VK, Google, Yandex?
