title: "Distributed high availability"
---

Distributed high-availability clusters are powered by [EDB Postgres Distributed](/pgd/latest/). They use multi-master logical replication to deliver more advanced cluster management compared to a physical replication-based system. Distributed high-availability clusters let you deploy a cluster across multiple regions or a single region. For use cases where high availability across regions is a major concern, a cluster deployment with distributed high availability enabled can provide:

- Two data groups with a witness group in a third region
- Three data groups

This configuration provides a true active-active solution as each data group is configured to accept writes.

To guard against cloud service provider failures, you can designate a witness node on a different cloud service provider than the data groups. This configuration can enable a three-region configuration even if a single cloud provider only offers two regions in the jurisdiction you are allowed to deploy your cluster in.

You can also change the cloud service provider of the witness node to be one of the other two cloud service providers.

Cross-cloud service provider witness nodes are available with AWS, Azure, and Google Cloud using your own cloud account and BigAnimal's cloud account. This option is enabled by default and applies to both multi-region configurations available with PGD. For witness nodes you only pay for the used infrastructure, which is reflected in the pricing estimate.
