This section covers enabling Global Writes on an Atlas cluster.
You can enable Global Writes in Atlas when you deploy an
M30or greater sharded cluster.
After you deploy the cluster, you can't convert a Global Cluster to a standard sharded cluster.
Due to sharding requirements, you can't load sample data onto a Global Cluster.
If this is the first dedicated paid cluster for the selected region or regions and you plan on creating one or more VPC peering connections, review VPC Peering Connections before continuing.

Each cloud provider has a selection of global regions to which Atlas can deploy a zone. The choice of cloud provider may support or constrict your ability to deploy a zone to specific geographic locations. The configuration options available and the cost for running the cluster may also vary depending on cloud provider selection.
Atlas provides three options for configuring your Global Cluster zones:
Configure Global Writes Zones Using a Template
Configure a Global Writes Single Region Zone
Configure a Global Writes Multi Region Zone
Select the appropriate tab based on how you would like to configure your Global Cluster zones.
To use Global Clusters, you must select a cluster tier
M30 or larger.
The selected tier dictates the memory, storage, vCPUs, and IOPS specification for each data-bearing server in the cluster.
This is the cluster name as it appears in Atlas. You can't change the cluster name once Atlas deploys the cluster.
Cluster names can't exceed 64 characters in length.
Atlas truncates the cluster name to 23 characters in its internal interactions. In practice, this means:
Cluster names shorter than 23 characters can't end with hyphen or dash (
Cluster names 23 characters or longer can't use a hyphen or dash (
-) as its 23rd character.
The first 23 characters in a cluster name must be unique within a project.
Don't include sensitive information in your cluster name.
