Is there a Lobby system?

Yeah! FlexMatch with backfill will work for that case. Here's how the flow would work for players using a matchmaking configuration with backfill:

1. First player joins matchmaking and that ticket creates a game session with 4 open slots - this game session acts as the lobby for other players to join
2. Another player joins matchmaking - they get matched with player 1 and joins the match in the backfilled spot
3. Game server updates FlexMatch with updated game status
4. Repeat 2-3 until the game session is full
5. Start the match in your game!

Hi Bhav,

Can you tell me what lobby features you are looking for specifically? Currently, GameLift offers FlexMatch as a matchmaking system that could be used to implement lobbies using backfill to find other players: https://docs.aws.amazon.com/gamelift/latest/flexmatchguide/match-backfill.html

Hi Alan, A lobby area would act as a waiting room for players who are waiting for a match or have been matched but are waiting for the team they are part of to be filled. For example, I wish to play as a member of team X and X requires 5 players before they can all join and play the join.

Does that make sense?
