2.2. Red Hat Storage Server for Public Cloud

Red Hat Storage Server for Public Cloud packages glusterFS as an Amazon Machine Image (AMI) for deploying scalable NAS in the AWS public cloud. This powerful storage server provides a highly available, scalable, virtualized, and centrally managed pool of storage for Amazon users. The Red Hat Server for Public Cloud provides highly available storage within AWS. Synchronous N-way replication across AWS Availability Zones provides high availability within an AWS Region. Asynchronous Geo-replication provides continuous data replication to ensure high availability across AWS regions. The glusterFS global namespace capability aggregates disk and memory resources into a unified storage volume that is abstracted from the physical hardware.
Red Hat Storage Server for Public Cloud is the only high availability (HA) storage solution available for AWS. It simplifies the task of managing unstructured file data whether you have few terabytes of storage or multiple petabytes. This unique HA solution is enabled by the synchronous file replication capability built into the glusterFS.
