Nitro System Innovation
summary
AWS describes end-to-end co‑design of Nitro silicon and EC2 software that moves I/O and hypervisor logic onto Nitro cards, freeing host CPUs and enabling 200 gigabits networking while doing encryption in hardware. Designs iterate with expensive chip turns (months and millions of dollars) mitigated by large‑scale emulation and formal verification. Features shown include Amazon SSD with Nitro ownership, SRD reliability protocol and EFA RDMA support, triple‑socket Graviton layouts for efficiency, and an audited no operator access model verified by NCC Group.
