## AI overview

This guide explains identity fragmentation across cloud accounts, data centers, and colocated infrastructure. It describes siloed identity systems, credential sprawl, and differing access models, and presents approaches including hardware roots of trust, short-lived certificates, shared certificate authorities, SPIFFE workload identities, reverse tunnels, and protocol-level enforcement.
