Phoenix DRaaS workflow

With Phoenix DRaaS, Amazon Machine Image (AMI) copies are created based on the virtual machine backup and maintained in the AWS account. At the time of disaster, you can launch EC2 instance from the AMIs, in-turn spinning up to production in minutes. Phoenix updates AMI copies with the latest virtual machine backup as per the defined schedule. The following diagram depicts the Phoenix DRaaS workflow:

Phoenix DRaaS components

When a disaster strikes the VMware environment, the following Phoenix DRaaS components work coherently to failover virtual machines, in-turn spinning up to production in minutes. 

  • Customer datacenter: Consists of a VMware setup registered with Phoenix for backup. The setup comprises a vCenter server or a standalone ESXi server. You can configure virtual machines on the VMware setup for backup by associating backup policies and retention policies with the virtual machines. Based on the backup schedules defined in the backup policy, data is backed up regularly to the Phoenix Cloud in AWS.
  • Customer AWS account: The account in AWS that acts as a secondary site for Phoenix DRaaS.
  • Phoenix AWS proxy: An EC2 instance in your AWS account that runs a Phoenix service. The Phoenix AWS proxy replicates data from the Phoenix storage to the AWS account and creates an AMI copy at a frequency specified in the disaster recovery (DR) plan.
  • Disaster recovery plan: The DR plan encompasses virtual machines configured for disaster recovery, the AWS account used for disaster recovery, the AMI update frequency, and the network, security, and instance-related failover settings, such as VPC, subnet, security group, IP addresses, and instance type. Preconfigure these settings in the DR plan for a single-click failover in the event of a disaster. On failover, based on the latest AMI and failover settings, an EC2 instance is launched in the AWS account.
