AWS Lambda SnapStart now supports functions packaged as container images
AWS Lambda has extended its SnapStart capability to support functions packaged as container images, significantly reducing their startup times from several seconds to sub-second. This opt-in feature helps developers build more responsive and scalable applications by taking a snapshot of the initialized execution environment. It is particularly beneficial for latency-sensitive workloads like ML inference and interactive APIs. SnapStart for container images is now available in most commercial AWS Regions.

- SnapStart support for Lambda container images
AWS Lambda SnapStart, which previously supported only managed runtimes, now extends its capability to functions packaged as container images. This allows for a dramatic reduction in startup times, as Lambda takes a snapshot of the initialized execution environment during deployment and resumes from it on invocation.
