EC2 안 Firecracker VM으로 브라우저를 1초 미만에 시작하기

Browser Use Cloud achieves sub-second browser startup by deploying individual Firecracker VMs per session on EC2, reducing costs by 66% while solving critical autoscaling limitations that previously caused 45-minute production outages. Their custom control plane replaces CloudWatch monitoring with real-time fleet management, demonstrating how nested virtualization and fine-grained orchestration unlock performance and cost benefits for ephemeral workloads at scale.
