Date: 2026-03-30 Purpose: Understand the scaling architecture so we know what we're building
Every production Firecracker platform (E2B, Fly.io, AWS Lambda) uses the same 3-component pattern:

Date: 2026-03-30 Context: Evaluating a bootstrapped SaaS opportunity — open-source Firecracker sandbox platform with managed cloud offering. Research conducted across competitive landscape, technical feasibility, market sizing, and business viability.
This document contains everything needed to build a Firecracker-based microVM platform with sub-20ms snapshot restore cold starts on bare metal servers. It is a technical reference for implementation — no product strategy, no brainstorming. Every claim is sourced from published papers, official documentation, or verified open source code.
The goal: replicate KraftCloud's core capability — stateful scale-to-zero with millisecond-class restore times — using open source components on commodity hardware.
