Could you build this?
No Building multi-tenant, ultra-low-cost, high-density secure Linux sandboxes with instant waking, metering, and port forwarding requires deep virtualization and hypervisor infrastructure.
What it would actually take: The stack relies on microVM technologies like Firecracker or container isolators like gVisor/Kata Containers, custom Linux kernel configurations, and a distributed orchestration control plane in Go/Rust. The hard engineering problems are sub-second cold starts, secure memory deduplication, safe tenant network isolation, real-time minute-level resource metering, and snapshotting active state to disk for pause/resume.

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
