[MENTION=394][EPIC] Josh.Markiewicz[/MENTION] Thank you very much Josh! I really appreciate the response 
I am using GameSparks as our backend platform. The current status of my project is I am able to login using user credentials and ping (connecting to data centers message…) my AWS instance (using TCP only. For some reason UDP is returning timeout error). After that player goes to main menu, choose their character and initiate matchmaking service (using GameSparks). I am able to spawn a new instance upon receiving the first player and save that information to the first player in the lobby but this is not a good procedure because the instance itself takes few minutes to spin up. But still, I am able to get the IP of the new instance and connect to that after it is up and running.
So I am very interested in learning this procedure you said here:
Can you please give a little more detailed explanation on how to do this?
