Previously, container fleets in Amazon GameLift used fixed CPU allocations that limited runtime performance or dense container packing. The new burstability feature allows containers to consume additional idle CPU resources on host instances during demand spikes, such as complex physics or AI calculations in gameplay.

This opt-in feature improves resource utilization while maintaining responsiveness for bursty game workloads. It is configurable per container group and available in all supported AWS Regions except China. The update comes at no extra cost, enabling developers to optimize server performance without sacrificing deployment density.
