:::tip SUPPORT, STABILITY, and DEPENDENCY INFO

Temporal Nexus is now Generally Available. Learn why you should use Nexus in the evaluation guide.

:::

Temporal Cloud builds on the core Nexus experience with:

• Global Nexus Registry - Scoped to your entire Account across all Namespaces. Workers in any Namespace can host Nexus Services for others to use.
• Built-in access controls - Restrict which caller Namespaces can use a Nexus Endpoint at runtime.
• Audit logging - Stream Nexus Registry actions (create, update, delete Endpoints) to your audit log integration.
• Multi-region connectivity - Nexus requests route across Namespaces within and across AWS and GCP using a global mTLS-secured Envoy mesh. Compatible with Multi-region Namespaces as Endpoint targets.
• Terraform support - Manage Nexus Endpoints with the Temporal Cloud Terraform provider.
