In the backend of a Web application I have to communicate with the public Ethereum Blockchain.

On local development machine, I run ganache as testrpc and connect with such a line of code:

web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));

I've also found out that I can develop against RinkeByRinkeby testnet with:

web3 = new Web3(new Web3.providers.HttpProvider("https://rinkeby.infura.io/$thisistheapikey"));

But how can I communicate with the REAL public Blockchain? Do I need to run geth on the Web server and connect to its instance? Or is there any public network available that could be used? (if we can trust it)?
