AWS announced the Nitro Isolation Engine, the first formally verified cloud hypervisor, using Isabelle/HOL to mathematically guarantee isolation correctness and security. The verification consists of a quarter-million-line formal proof that executes in 30 minutes on standard hardware. This advancement applies rigorous mathematical verification to critical cloud infrastructure protecting customer data.
