Amazon DocumentDB now supports Global Clusters in the AWS GovCloud (US-East and US-West) Regions. The AWS GovCloud (US) Regions are isolated AWS Regions designed to host sensitive data and regulated workloads in the cloud, assisting customers who have United States federal, state, or local government compliance requirements. Global Clusters in the AWS GovCloud Regions provide disaster recovery from region-wide outages and enable low-latency global reads by allowing reads from an Amazon DocumentDB cluster in the nearest AWS GovCloud Region.ENnbsp;

Global Clusters uses fast, storage-based replication across regions with latencies typically less than one second, using dedicated infrastructure with no impact to your workload’s performance. In the unlikely event of a regional degradation, one of the secondary regions can be promoted to full read/write capabilities, typically in less than one minute.ENnbsp;Each secondary region can have up-to 16 replica instances.

Global clusters is available starting DocumentDB v4.0. You can create a new Global Cluster or add regions to existing clusters with just a few clicks on the Amazon DocumentDB Management Console or download the latest AWS SDK or CLI.ENnbsp;
