Maximizing Availability with Multi-region Namespaces

We are introducing Multi-region Namespaces (formerly known as Global Namespaces), now available in Public Preview.

Customers rely on Temporal to power their most critical workloads. While Temporal Cloud offers 99.99% availability for all Namespaces, a Multi-region Namespace offers a contractual service level agreement (SLA) of 99.99% guarantee against service errors.

This is achieved through an “active-standby” setup managed by Temporal. Workflows are replicated by Temporal Cloud to a standby region as defined by the user. If there is an outage or an incident in the active region, the namespace is seamlessly “failed over” to the standby region, thus minimizing any disruption.

For workflows in the critical path of revenue or user experience, Multi-region Namespaces offer customers a guarantee and peace of mind, with no additional effort required. Temporal Cloud has automated the process of replication, workflow migration, and failover – allowing customers to rest easy.

Here is a highlight of the benefits offered by Multi-region Namespaces

  • Reduce risk & minimize operational disruption: Ensure that your workloads remain available, even during unexpected outages. Seamless failover shifts workflow executions to a standby region during outages, without the need for any manual synchronization
  • No manual deployment, configuration or code changes needed: Temporal Cloud simplifies the deployment process with push-button operations. This eliminates the need for any changes on your end

A fun fact is that we have been dogfooding our own replication technology in Temporal Cloud for over a year, so it has been battle-tested and is ready to offer high-availability and reliability to our customers!
