AWS Elastic Disaster Recovery vs Xen Orchestra

AWS Elastic Disaster Recovery recovers on-premises and cloud applications on AWS to reduce downtime and data loss. Recovery instances can launch within minutes from the latest server state or an earlier point in time. Afterward, replicated data can return to the primary site for failback, and non-disruptive recovery and failback drills can run while replication continues. Sources include physical infrastructure, VMware vSphere, Microsoft Hyper-V, and other cloud providers. Supported workloads run on supported Windows and Linux versions, including Oracle, MySQL, SQL Server, and SAP. Recovery targets include EC2 instances in another Availability Zone or AWS Region. Point-in-time recovery can provide an operational copy from before a security incident. Replication uses TLS 1.2 in transit and can use Amazon EBS encryption at rest, with VPN, Direct Connect, or VPC peering for private connectivity. The service supports up to 300 servers in one staging account and up to 3,000 in one target account using multiple staging accounts. Pricing is $0.03 per month, billed $0.028 per source server per hour; additional AWS resource charges apply.
