Replication and High Availability Cloud Scenarios › Overview

Overview

Effective with this release, you can replicate and provide application high availability in the cloud. The Full System Data Replication/High Availability to EC2 feature is an extension to the existing full system scenario type where CA ARCserve RHA enables replication and high availability of an entire Windows system into a VM running on Microsoft Hyper-V, Citrix Xen, or VMware ESX Hypervisor. The Full System Data Replication/High Availability to EC2 feature extends the list of supported virtual environments by adding support for Amazon EC2.

To create a full system HA or replication scenario with an EC2 replica, ensure the following prerequisites are met:

• You must have an account with Amazon Web Services (AWS).
• You must have a configured VPC (Amazon Virtual Private Cloud) and have created the VPN connection between the on-premises network (where the master servers reside) and the VPC.

  Note: More information about Amazon VPC is described on the Amazon website.

  

After these requirements are met, you replicate and provide application high availability by performing these steps and using these features:

• Use the CA ARCserve RHA Replication to Cloud option in the Scenario Creation Wizard.
  • Register the AWS account and credentials in CA ARCserve RHA
  • Retrieve the VPC ID associated to the account
  • Decide the EC2 instance and launch it
  • Remotely deploy the CA ARCserve RHA Engine
  • Use CA ARCserve RHA as usual
• New CA ARCserve RHA interface tab for cloud management (Cloud View).
  • Shows list of managed AWS accounts, instances, snapshots, EBS volumes, elastic IPs, security groups and so on.
