HashiCorp has released a new feature in Nomad Enterprise 0.12 called Multi-Cluster Deployment, which enables the deployment of applications across multiple clouds and datacenters with a single unified monitoring and control plane. This feature allows organizations to deploy applications seamlessly to federated Nomad clusters with configurable rollout and rollback strategies, achieving high availability, built-in flexibility, no setup needed, and fully supported by HashiCorp. The new feature simplifies the process of deploying multi-cluster applications without requiring additional namespaces, topology, or configuration changes. It also provides a more coordinated approach to rolling out deployments across regions, allowing for automatic blocking and unblocking of regions as needed. Additionally, the feature includes support for failure handling, including the option to allow a region to fail all remaining regions or only mark itself as failed.
