AWS has announced support for microVM snapshots in AWS Lambda, allowing functions to start from pre-initialized Firecracker microVM snapshots instead of creating new execution environments from scratch.
The feature helps reduce cold-start latency, particularly for applications with lengthy initialization processes, while preserving the security and isolation benefits of Firecracker-based execution. By restoring a saved microVM state, Lambda can make compute resources available more quickly and deliver more consistent performance for latency-sensitive workloads.
AWS says the enhancement improves the developer experience for serverless applications and supports faster scaling while maintaining the operational simplicity of AWS Lambda.
