Temporal Nexus, now generally available, is a robust tool designed to connect Temporal Applications across isolated Namespaces, offering benefits such as improved modularity, security, debugging, and fault isolation with Durable Execution. It allows seamless inter-service communication with built-in observability and multi-region connectivity in Temporal Cloud across AWS and GCP, supporting companies like Netflix and Miro in building and managing complex workflows. Nexus simplifies the integration process by allowing teams to own their own Namespaces while facilitating cross-namespace calls without sharing excessive data, thus reducing the burden of managing security and failure scenarios. The platform supports Nexus Services through the Go SDK and Java SDK and enhances reliability with execution guarantees, while also providing enhanced capabilities in Temporal Cloud, such as policy enforcement and multi-cloud connectivity. The Nexus roadmap focuses on expanding connectivity, improving developer experience across different languages, and enhancing visibility and control for shared services.
