3.4. High Availability and Flexibility

Synchronous n-way file replication ensures high data availability and local recovery. Asynchronous geo-replication ensures resilience across data centers and regions. Both synchronous n-way and geo-replication asynchronous data replication are supported in the private cloud, data center, public cloud, and hybrid cloud environments. Within the AWS cloud, Red Hat Gluster Storage supports n-way synchronous replication across Availability Zones and asynchronous geo-replication across AWS Regions. In fact, Red Hat Gluster Storage is the only way to ensure high availability for NAS storage within the AWS infrastructure.
