AWS Lambda introduces MicroVMs to replace traditional container-based execution environments, offering enhanced isolation and performance for serverless workloads. This architectural shift allows for faster cold starts and stronger security boundaries by leveraging lightweight virtual machines instead of shared containers.
Background
AWS Lambda has historically used container-based sandboxing for function isolation, which can lead to slower cold starts and potential tenant noise. The move to MicroVMs represents a significant evolution in serverless infrastructure design.
