Firecracker is an open-source virtualization technology developed by AWS for deploying secure micro-VMs (microVMs) that offer strong isolation with minimal overhead. Designed for serverless workloads (e.g., AWS Lambda, Fargate), it combines VM-level security with container-like performance and startup speed.
Features
- Creates lightweight microVMs with KVM-based hardware isolation
- Extremely fast startup and low memory footprint for serverless tasks
- Minimalist design reduces attack surface and resource usage
- Useful for multi-tenant, secure compute platforms
- Integrates with container orchestration tools like Kubernetes
- Written in Rust/Python for performance and reliability
