What are Firecracker microVMs and why E2B chose them?
What is a MicroVM?
A microVM (micro virtual machine) is a lightweight virtual machine designed to provide the security and isolation of traditional VMs while maintaining the resource efficiency and rapid startup times of containers². MicroVMs achieve this through a minimalist approach that includes only essential components needed to run applications, eliminating unnecessary OS services and drivers.
Unlike traditional VMs, which typically require ~131 MB of memory overhead and boot in seconds, microVMs are optimized for minimal resource usage with only 3-5 MB of memory overhead per instance and can boot in ≤125 ms (pre-configured) to ~160-180 ms end-to-end². MicroVMs leverage KVM-based hardware virtualization to provide hardware-enforced isolation, preventing malicious code from compromising the host system while maintaining the speed and resource efficiency of containers.
E2B's Firecracker implementation
E2B uses Firecracker microVMs instead of traditional containers. Firecracker is AWS's purpose-built Virtual Machine Monitor (VMM) written in Rust with approximately 50,000 lines of code compared to QEMU's 1.4 million lines².
Firecracker introduces MicroVMs as a minimalist virtual machine abstraction that combines the security isolation of traditional VMs with the speed and resource efficiency of containers². Key design principles include:
- RESTful API control: Each MicroVM is configured and controlled via a RESTful API over a UNIX socket, enabling asynchronous setup and fast "start" calls²
- Minimal device emulation: Scoped to essentials—virtio block and network, serial console, and minimal keyboard controller—trading flexibility for dramatically reduced Trusted Computing Base²
- Built-in rate limiting: Token-bucket rate limiters on disk and network I/O enforce bandwidth and IOPS caps per MicroVM, ensuring noisy-neighbor containment²
Architecture and Thread Model

Each Firecracker process encapsulates one microVM and runs three types of threads³:
- API thread: Handles Firecracker's REST API server and control plane
- VMM thread: Manages the machine model and device emulation
- vCPU threads: Execute guest code via KVM (one thread per virtual CPU)
Security and Isolation
Firecracker implements multi-layered security³:
- Hardware-level isolation with KVM-based virtualization and separate kernels per sandbox²
- Jailer process: In production, runs Firecracker in a secure sandbox with dropped privileges, cgroups, and namespaces³
- Thread-specific seccomp filters: Limit system calls per thread type for enhanced security³
- Minimal attack surface through limited device emulation (VirtIO block/network, serial console)²
Performance and Resource Management
- Memory overhead: ~3-5 MB per MicroVM, regardless of guest memory size (versus ~131 MB for QEMU)²
- Boot latency: Cold-start to guest init in ≤125 ms (pre-configured) and ~160-180 ms end-to-end (including API calls), roughly 2× faster than QEMU²
- Creation throughput: Up to 150 MicroVMs per second per host without contention²
- Rate limiting: Built-in token bucket algorithm for I/O operations to ensure fair resource usage³
- Production scale: Supports millions of simultaneous workloads and processes trillions of serverless invocations per month in AWS Lambda and Fargate²
- Persistent state management across code executions with up to 24-hour session duration¹
Serverless Specialization and Production Readiness
Firecracker's design reflects specialization for serverless workloads, enabling massive simplification²:
- Focused scope: Drops legacy device support, VM migration, BIOS, and PCI emulation to focus on the 80% of use-cases that power functions and containers²
- Memory safety: Rust's memory safety combined with minimal VMM features reduces attack surface compared to monolithic hypervisors²
- Economic efficiency: Fast startup and low overhead enable high levels of oversubscription and soft resource allocation, delivering multi-tenant serverless benefits without compromising isolation²
- Production validation: Seamless AWS Lambda migration from containers to Firecracker showed no customer-visible regressions, demonstrating production readiness²
Technical comparison
The following comparison is based on the official Firecracker research²:
| Dimension | Linux Containers | QEMU/KVM Virtualization | Firecracker MicroVMs |
|---|---|---|---|
| Security | Depends on kernel syscalls and namespaces; tradeoffs between compatibility and syscall filtering | Full guest kernel, hardware-enforced isolation, large TCB (QEMU+KVM) | Hardware-enforced isolation via KVM, minimal Rust VMM (≈50 KLOC), seccomp-bpf jailer |
| Resource Overhead | Negligible per container; shared kernel footprint | ~131 MB per VM; seconds-scale boot | ~3–5 MB per MicroVM; < 150 ms boot |
| Boot Time | Milliseconds (container start) | Seconds (VM) | 125–180 ms |
| Feature Scope | Full Linux API surface | Broad device and BIOS emulation | Minimal device set (virtio block, net, serial) |
| Multi-Tenancy | Soft isolation, noisy-neighbor risk | Strong isolation, high overhead | Strong isolation, low overhead |
Why E2B chose Firecracker
E2B's architectural decision to adopt Firecracker microVMs was driven by specific technical requirements for AI code execution platforms:
Security and isolation requirements
E2B requires strong isolation for executing untrusted AI-generated code. Firecracker provides hardware-level isolation via KVM-based virtualization, ensuring each sandbox operates with its own kernel and preventing cross-tenant attacks. Unlike container-based solutions that share the host kernel, Firecracker's minimalist design reduces the attack surface by excluding unnecessary devices and guest functionality.
Performance requirements
AI development workflows require rapid environment provisioning to maintain developer productivity. Firecracker's ≤125 millisecond boot times enable near-instantaneous sandbox creation, while the <5 MiB memory overhead per microVM allows for high-density deployments essential for multi-tenant platforms.
Resource efficiency
E2B's cloud infrastructure requires efficient resource utilization for cost-effective scaling. Firecracker's built-in rate limiters for network and storage resources enable optimized sharing across thousands of concurrent microVMs, while the minimal resource footprint allows high-density deployment on single hosts⁶.
Persistent state management
AI agents require stateful development environments that maintain installed packages, file systems, and project state across sessions. Firecracker's VM-based architecture provides native filesystem persistence without requiring complex external state management systems, supporting E2B's up to 24-hour session duration.
Technical challenges
Achieving fast cold starts with full VM isolation
The cold start problem represents a fundamental challenge for AI code execution platforms: the latency between a user request and when code can actually execute. Traditional solutions force a choice between security (slow VM startup) or speed (fast but vulnerable containers).
- Containers: Fast startup (~50-200ms) but shared kernel vulnerabilities
- Traditional VMs: Strong isolation but slow startup (seconds) and high memory overhead (~131MB)
- Required solution: VM-level security with container-like performance
By leveraging Firecracker's microVM technology, E2B achieves <200ms sandbox initialization and "effectively eliminate cold starts" for AI applications, providing immediate responsiveness while maintaining VM-level security isolation required for untrusted code execution.
Further optimizations:
- Pre-warmed infrastructure: E2B maintains ready microVM pools to reduce allocation latency
- Hardware isolation with minimal overhead: Firecracker's ~5 MiB memory footprint enables high-density deployments
- Session persistence: Up to 24-hour session duration eliminates repeated cold starts for ongoing workflows
Template-based environment provisioning and VM pooling
E2B implements a sophisticated template-based resource management system that enables efficient resource reuse through pre-built, snapshotted environments that can be rapidly instantiated multiple times.
Template creation and snapshotting
Template build process
Templates are created using the e2b template build command, which builds sandbox templates from Dockerfiles and converts them to microVM snapshots. The system uses an e2b.toml configuration file to store template metadata including resource specifications with configurable CPU and memory settings. Docker images serve as build artifacts during template creation but are converted to Firecracker microVM snapshots for runtime execution.
Template lifecycle process
The template creation process involves several key steps that optimize resource utilization:
graph TD
A[Dockerfile Input] --> B[Docker Image Build]
B --> C[Convert to MicroVM]
C --> D[Dependency Installation]
D --> E[Start Command Execution]
E --> F[Environment Readiness Check]
F --> G[VM State Snapshotting]
G --> H[Template Ready for Use]
B1[Standard Docker build<br/>process] --> B
C1[Convert Docker image<br/>to Firecracker microVM] --> C
E1[Pre-initialize services<br/>Seed databases] --> E
F1[Verify all services<br/>running correctly] --> F
G1[Serialize complete VM state<br/>Save as reusable snapshot] --> G
This process transforms a standard Dockerfile into a pre-configured, snapshotted microVM that can be instantly restored without rebuilding. The final output is a Firecracker microVM snapshot, not a container image.
Snapshotting technology
This snapshotting approach captures the complete running state, including all processes and filesystem changes, allowing for near-instantaneous restoration and eliminating the need to rebuild environments from scratch for each sandbox.
Node-based orchestration and resource management
Cluster resource tracking
E2B manages resources through a cluster of nodes, where each node monitors:
- CPU allocation: Total CPU cores allocated across running sandboxes
- Memory tracking: Real-time memory usage across all instances
- Sandbox capacity: Current running instances and sandboxes being started
Local template caching
Each cluster node maintains locally cached templates - pre-built environments stored locally for immediate sandbox creation, reducing startup latency by eliminating the need to fetch and prepare VM images from remote storage.
Node state management
The platform employs a node-based orchestration system for managing sandboxes across a distributed cluster. Each node tracks critical metrics including allocated CPU cores, allocated memory, sandbox count, and operational status:
graph TB
subgraph "Node Orchestration System"
subgraph "Node States"
Ready[Ready<br/>Available for workloads]
Draining[Draining<br/>Completing existing work]
Connecting[Connecting<br/>Joining cluster]
Unhealthy[Unhealthy<br/>Removed from rotation]
end
subgraph "Node Metrics Tracking"
AllocCPU[Allocated CPU Cores]
AllocMem[Allocated Memory]
SandboxCount[Running Sandboxes]
StartingCount[Starting Sandboxes]
end
subgraph "Load Distribution"
Scheduler[Workload Scheduler]
CapacityPlanner[Capacity Planner]
LoadBalancer[Load Balancer]
end
Ready --> Scheduler
Draining --> Scheduler
Connecting --> Scheduler
Unhealthy --> Scheduler
AllocCPU --> CapacityPlanner
AllocMem --> CapacityPlanner
SandboxCount --> LoadBalancer
StartingCount --> LoadBalancer
end
Nodes can be in various states (ready, draining, connecting, or unhealthy), providing the orchestration system with granular control over resource allocation and workload distribution.
Resource allocation specifications
The system uses predefined resource specifications with minimum requirements of 1 CPU core and 128MB memory. Sandbox creation requests specify template ID and resource parameters, allowing the orchestrator to schedule VMs on appropriate nodes based on available capacity.
Advanced resource optimization
Start command pre-initialization
Templates support start commands that pre-initialize services and applications, reducing runtime startup overhead. This feature allows running servers or seeded databases to be ready immediately when spawning sandboxes, eliminating wait times during runtime.
Pause and resume functionality
The system supports pause and resume functionality, allowing VMs to be temporarily suspended while preserving state, effectively extending the pre-warmed pool concept to running instances.
Template management operations
E2B provides comprehensive template management through CLI commands:
- Template listing: View all templates with their resource allocations
- Template publishing: Share templates across teams for resource standardization
- Template deletion: Clean up unused templates to free resources
This template-based architecture represents a sophisticated approach to environment reuse that significantly reduces resource overhead compared to traditional container-per-request models, enabling sub-second sandbox startup times while maintaining full isolation between instances.
Security and isolation models
E2B implements a multi-layered security and isolation model that combines Firecracker microVM isolation, dual authentication mechanisms, and secure communication protocols to provide safe execution environments for AI agents.
Authentication and access control
Dual authentication model
E2B uses a dual authentication architecture where API keys authenticate with the main API while access tokens secure communication with individual sandbox environments:
graph TB
subgraph "E2B Security Architecture"
Client[AI Agent/Client] --> API[Main API Server]
API --> |API Key Auth| Lifecycle[Sandbox Lifecycle]
API --> |Generate| Token[Access Token]
Token --> |Secure Auth| Sandbox1[Sandbox Environment 1]

subgraph "Sandbox Security"

Sandbox2 --> EnvD2[Environment Daemon]
EnvD1 --> MicroVM1[Firecracker MicroVM]
EnvD2 --> MicroVM2[Firecracker MicroVM]
end
subgraph "Communication Protocols"
REST[REST API<br/>Lifecycle Management]
GRPC[gRPC Protocol<br/>Real-time Operations]
end
API --> REST
Token --> GRPC
end
Optional Secure Mode
The system supports an optional secure mode that requires access token authentication for all sandbox operations. When enabled, this mode generates per-sandbox access tokens that must be included in all subsequent requests.
MicroVM-based isolation
Each sandbox runs as an isolated Firecracker microVM with its own environment daemon (envd) that provides secure access to filesystem, process, and terminal operations. The sandboxes are built from Docker images that are converted to microVM snapshots through customizable templates, providing VM-level security boundaries while maintaining rapid startup capabilities.
Secure communication architecture
Dual protocol design
The platform uses dual protocols for different types of operations:
- REST API: Sandbox lifecycle management (create, kill, timeout) with API key authentication
- gRPC Protocol: Real-time operations (filesystem, commands, terminals) with access token authentication
All gRPC communications include authentication headers when access tokens are available, ensuring secure communication channels between clients and sandbox environments.
Network security
All communications use HTTPS/TLS encryption for data in transit, with the system automatically switching between HTTP (debug mode) and HTTPS (production) based on configuration.
File access security
Signature-based access control
E2B implements signature-based file access control for enhanced security. In secure mode, file upload and download operations require cryptographic signatures that include the file path, operation type, user, and access token.
Time-limited access
The signature system supports time-limited access with configurable expiration times, providing fine-grained control over file access permissions. Without proper signatures in secure mode, file access requests are rejected with authentication errors.
Runtime environment isolation
Multi-layer isolation architecture
E2B implements defense-in-depth isolation through multiple security boundaries, from hardware to application level:

Security boundary analysis:
- Layer 1 (Hardware): KVM-based virtualization with CPU-level isolation (Intel VT-x/AMD-V)
- Layer 2 (Hypervisor): Firecracker VMM with minimal attack surface (~50,000 vs 1.4M lines)
- Layer 3 (Guest OS): Separate Linux instances with isolated filesystems per microVM
- Layer 4 (Application): Environment daemon access control and process isolation
Firecracker microVM isolation
Each sandbox operates within its own isolated Firecracker microVM with hardware-level security boundaries and controlled access to system resources. The environment daemon runs on a dedicated port (49983) within each microVM and manages all interactions within the sandbox.
VM snapshotting technology
E2B leverages VM snapshotting technology that allows the entire VM state (filesystem + running processes) to be serialized and restored in ~150ms. This enables rapid instantiation of pre-configured environments while maintaining complete isolation between sandboxes.
Lifecycle management
Sandboxes have timeout-based lifecycle management where microVMs are automatically terminated after a specified duration, providing resource cleanup and preventing long-running processes from consuming system resources indefinitely.
Infrastructure and scaling patterns
E2B's infrastructure design enables scalable AI code execution by building upon the technical foundations described earlier. The platform's scaling strategy leverages its Firecracker microVM architecture, template-based provisioning, and node orchestration to support diverse workload patterns¹¹.
