Standard container runtimes like runc share the host kernel, providing process-level isolation that is sufficient for many workloads but inadequate for multi-tenant environments, untrusted code execution, or compliance-driven architectures. This guide compares three runtime isolation approaches: Sysbox for inner workloads, Firecracker for micro-virtual machines, and gVisor for application kernel sandboxing.</p>
