PlayFab
Microsoft's managed platform covers player data, content configuration, economy, experiments, matchmaking, servers, and events.
Why use it
Use PlayFab to avoid rebuilding risky online infrastructure and scale from development mode into production.
Where it fits
Use analytics, feedback, player support, and updates to fix issues and decide what to improve after launch.
What to check
Production billing spans multiple usage meters; secrets, economy writes, and authoritative logic must stay off the client.
