AWS Fargate excels as a serverless container deployment platform but lacks the persistent workspace capabilities AI agents need — Fargate’s ECS Exec has 20-minute session timeouts, ephemeral storage constraints, and no true terminal persistence, while agents need durable runtime environments that can mutate the machine, inspect what changed, start and stop processes, and attach to terminals. Freestyle VMs offer session preservation, environment forking, SSH access, and integrated service routing that align with how agents actually operate.
