Azure Key Vault Managed HSM (Hardware Security Module) is a fully managed cloud service that offers FIPS 140-2 Level 3 validated HSM to protect against physical access or modification of the HSM. Managed HSM Pools provide highly available and zone resilient clusters to protect against hardware failure. Managed HSM instances are partitions on a shared HSM within a single tenant security FIPS certified boundary. Note that managed HSM pools are not available in all regions, for example Australia East is expected in Q4 2021.
