lets you configure applications for high availability (HA) and disaster recovery (DR) in Amazon Web Services (AWS) cloud.
provides the AWSIP agent and the Route53 agent to manage the network resources for cluster communication, failover, and failback. The agents monitor and manage the IP resources within cluster nodes in the AWS cloud or cluster nodes that are spread across on-premises and AWS. For more information on the agents, see the Cluster Server 7.3 Bundled Agents Reference Guide - Linux.
Note: |
Veritas recommends that you configure three coordination point servers (CP servers) in three different availability zones (AZs) to manage I/O fencing. |
Application data is data is stored on the Elastic Block Store (EBS) volumes that are attached to Elastic Compute Cloud (EC2) instances. In case of clusters with two or more nodes, the Flexible Storage Sharing (FSS) feature enables network sharing of the EBS volumes. Thus, application data can be shared between the cluster nodes. For more information on FSS, see the Storage Foundation Cluster File System High Availability 7.3 Administrator's Guide - Linux.
lets you configure replication between EC2 instances, which is further used to support various HA and DR scenarios for applications in AWS.
