> Temporal Cloud adds global Nexus Registry, built-in access controls, audit logging, and multi-region connectivity on top of core Nexus.

Temporal Cloud builds on the [core Nexus experience](/nexus) with:

- **Global [Nexus Registry](/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](/nexus/registry#configure-runtime-access-controls)** - Restrict which caller Namespaces can use a Nexus Endpoint at runtime.
- **[Audit logging](/cloud/audit-logs)** - 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 Namespaces that have [High Availability](/cloud/high-availability) as Endpoint targets.
- **[Terraform support](/cloud/terraform-provider#manage-temporal-cloud-nexus-endpoints-with-terraform)** - Manage Nexus Endpoints with the Temporal Cloud Terraform provider.
