AWS and Azure Multi-AZ for environments and Data Lakes
By default, Cloudera provisions Data Lake, FreeIPA, and Data Hubs in a single AWS or
Azure availability zone (AZ). You can choose to deploy them across multiple availability
zones (multi-AZ). It is possible to enable it for all the components or a few
components.
You can choose to deploy your Cloudera environment (FreeIPA and Data Lake) and
Data Hubs across multiple subnets and availability zones, where you can deploy each of
these components across three or more availability zones to provide high availability
and fault tolerance. The following diagram illustrates this scenario where each of the
components (FreeIPA, Data Lake, and Data Hubs) are deployed across multiple subnets and
multiple availability zones (eu-central-1a, eu-central-1b, and
eu-central-1c):
