Nexus - Temporal Cloud feature guide

SUPPORT, STABILITY, and DEPENDENCY INFO

Temporal Nexus is available in Public Preview. Learn why you should use Nexus in the evaluation guide.

Temporal Nexus allows you to connect Temporal Applications across (and within) isolated Namespaces. This provides all the benefits of Durable Execution across team and application boundaries with improved modularity, security, debugging, and fault isolation. Nexus supports cross-team, cross-domain, cross-namespace, and multi-region use cases.

Nexus Overview

Temporal Cloud support is built on top of the core Nexus experience and adds a global Nexus Registry within an Account, enhanced security, and multi-region connectivity.

RELATED

Global Nexus Registry​

The Nexus Registry in Temporal Cloud is scoped to an Account. Workers in any Namespace can host Nexus Services for others to use within an Account.

Built-in access controls​

Temporal Cloud has built-in Endpoint access controls to restrict which callers can use a Nexus Endpoint.

Audit logging​

Temporal Cloud supports audit log streaming for Nexus Registry actions to create, update, or delete Endpoints.

Multi-region connectivity​

Nexus requests in Temporal Cloud are routed across Namespaces using a global mTLS-secured Envoy mesh. Built-in Nexus Machinery provides reliable at-least-once execution and Workflow policy can deduplicate requests for exactly-once execution, even across multi-region boundaries.
