your solution do not specify if running two instances will utilize two copies of the blockchain or use the same ? Also, will this procedure run two wallets simultaneously or only one instance can run at any given moment ? Thanks

How should I use it with json-rpc? There is no wallet_name parameter in send not list_transactions. So is it possible to run 2 wallets concurrently? So I send coins from one wallet and receive it in another but having just one blockchain and not doing service restart or wallet unload/load between?

0.17 (and I think 0.16) has support for multiple wallets in one bitcoind. Even runtime adding/removing/switching wallets. You can manage those using RPC commands. Multiple bitcoind instances can not share the same blockchain files. No experience with this, so can't comment on best practices.

Thanks @Jannes! Following your answer, I researched a bit and wrote an official answer to that question.

# Using multiple wallets on one "bitcoind" process

### Follow this steps:

1. Run the bitcoind process.
2. Create a wallet for each of the clients using:

`bitcoin-cli.exe createwallet`

3. When you want to perform any action on any wallet simply use:

`bitcoin-cli.exe -rpcwallet=`

4. Use `""` for  in order to refer to the default wallet, created by the bitcoind.
