Former AWS EKS engineer Justin Garrison reveals that AWS Fargate does not actually use Firecracker microVMs for container isolation, despite marketing materials suggesting otherwise. The article argues AWS deliberately allowed this misconception to persist, leveraging Firecracker's reputation while relying on different underlying technology. The piece also touches on political and organizational factors that prevented correction of this narrative at scale.
